Relevance to life<br />2. Formulas<br /><br />I have always been more drawn to algebra and those types of math problems. I have never been a big fan of geometry (Yes, I know! You get it! I don't really like geometry!) But if you really break down geometry, you do indeed get the two things I like about math. Relevance and formulas. You can try to argue against it, but geometry is very relevant in our everyday lives. You want to know how much will fit into a container? Guess what you are doing geometry! My husband and I are going to buying some river rock to finish off some landscaping in our yard. Yup, you guessed it geometry. No, you say, that is measuring, that is not triangles and trapezoids. Wrong again. Measuring goes hand in hand with shapes and you got it, geometry!<br /><br />Measuring can be easy if you just learn a few equivalences. For example how nice is it if you are cooking and you want to make another half batch of something, knowing how much you need to add can really save you a lot of time and waste.<br /><br />Here are some examples of some equivalences:<br /><br />1 yard = 3 feet<br />1 mile = 1,760 yards = 5,280 feet<br />1 sq foot = 144 square inches<br />1 pint = 2 cups<br />1 quart = 2 pints<br />1 gallon = 4 quarts<br />1 pound = 16 ounces<br /><br />Here is a little video on measurement.<br /><br /><div class="separator" style="clear: both; text-align: center;"><object class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://0.gvt0.com/vi/DQPQ_q59xyw/0.jpg" height="266" width="320"><param name="movie" value="http://www.youtube.com/v/DQPQ_q59xyw&fs=1&source=uds" /><param name="bgcolor" value="#FFFFFF" /><embed width="320" height="266" src="http://www.youtube.com/v/DQPQ_q59xyw&fs=1&source=uds" type="application/x-shockwave-flash"></embed></object></div><div class="separator" style="clear: both; text-align: center;"><object class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://0.gvt0.com/vi/DQPQ_q59xyw/0.jpg" height="266" width="320"><param name="movie" value="http://www.youtube.com/v/DQPQ_q59xyw&fs=1&source=uds" /><param name="bgcolor" value="#FFFFFF" /><embed width="320" height="266" src="http://www.youtube.com/v/DQPQ_q59xyw&fs=1&source=uds" type="application/x-shockwave-flash"></embed></object></div>Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-20265240029548043842011-07-25T03:50:00.000-07:002011-07-25T03:53:23.512-07:001510 Week 6What is a rational number?<br /><br />I look at the above question and I think, "It's a..um...it's a number that is.....you know....rational. That makes sense." The definition according to the book "Mathematics for Elementary School Teachers" is "the quotient of a pair of integers (a/b, b is not equal to 0) that can be represented by a fraction or a decimal."<br /><br />Like most math definitions, I think it sounds a bit more complicated than it really is. So I took to Google. What is a rational number? One site stated that it is any number that can be written as a simple fraction. Well that makes sense. I found this video on youtube that really helps clarify this.<br /><br /><div class="separator" style="clear: both; text-align: center;"><object class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://3.gvt0.com/vi/pIRb7F7tKEM/0.jpg" height="266" width="320"><param name="movie" value="http://www.youtube.com/v/pIRb7F7tKEM&fs=1&source=uds" /><param name="bgcolor" value="#FFFFFF" /><embed width="320" height="266" src="http://www.youtube.com/v/pIRb7F7tKEM&fs=1&source=uds" type="application/x-shockwave-flash"></embed></object></div><br />Another real life math example...I love it! <br /><br />So I do find this area of math pretty easy to understand. Understanding the meaning behind the math really helps solidify it is my mind. I guess that is the "Why?" Ok, so moving on to adding or subtracting rational numbers, like a decimal. It seems so "elementary" but I sometimes forget the basics behind the "easy" math because of the convenience of calculators. My current job is a banker. I work with numbers all day long. I NEVER use a piece of paper and pencil to figure out a deposit or interest, or a payment etc. I use the computer or a calculator. Can I do it without, sure. But, I don't want to make a mistake or take too long. Let's test my skills. Honest, no calculator.<br /><br /> 56.45<br /><u>+82.67</u><br /> 139.12 <br /><br />YES! I can do it. I know where to carry the decimal because there are only 2 places. Now let's try a little harder one and see how I do.<br /><br /> 45.88769<br /><u>+ 23.882</u><br /> 69.76969<br /><br />Got it! Whew. I will be honest, I was a little nervous because the decimals are not the same and I promised to use only my mad skills. All I did was added 2 zeros to the end to get my answer.<br /><br /> 45.88769<br /><u>+23.88200</u><br /><br />I have to say, throughout this experience of recording my thoughts and what I have learned during his math course, I still get a smile when I get the answer right. Even if it is "easy". Come on, let's celebrate the right answer!<br /><br />Another area I feel like I feel I should celebrate my understanding is adding and subtracting fractions and mixed fractions. Another "Duh." section, you say? . But, come on! How many really remember how to do it. I will tell you, I took my Praxis test (pretest for elementary teachers) and failed the math portion. Yup. I told myself no kidding you failed! When was the last time I added fractions?! Or did simple geometry on my own?! Too long. Well, I am retaking it now! You see what I have learned.....<br /><br />3/4 + 2/3 = 17/12 or 1 5/12<br /><br />(Little smile). I will leave you with this song by Tom Lehrer.<br /><br /><div class="separator" style="clear: both; text-align: center;"><object class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://3.gvt0.com/vi/NfqSTfTwJE8/0.jpg" height="266" width="320"><param name="movie" value="http://www.youtube.com/v/NfqSTfTwJE8&fs=1&source=uds" /><param name="bgcolor" value="#FFFFFF" /><embed width="320" height="266" src="http://www.youtube.com/v/NfqSTfTwJE8&fs=1&source=uds" type="application/x-shockwave-flash"></embed></object></div>Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-91014604928405313552011-07-12T20:20:00.000-07:002011-07-24T20:08:20.690-07:001512 Week 5Geometry, Geometry and more Geometry. Sigh.<br /><br />Let's face it, I am not excited about geometry. Instead of talking about geometry this week, I am going to talk about staying excited as a teacher. Even when I don't really like the subject.<br /><br />So......how do you make it fun? I think hands on is a great way to make it fun. So have the students draw geometric shapes like triangles, sort shapes and draw reflections. A favorite website of mine is Enchanted Learning <a href="http://www.enchantedlearning.com/math/geometry/shapes/">http://www.enchantedlearning.com/math/geometry/shapes/</a> this site gives worksheets on many different subjects. I just love it.<br /><br />Games are another way to make geometry fun. Brain pop is a great resource for games and interactive quizzes that help the class work together as a team. <a href="http://www.brainpop.com/math/geometryandmeasurement/">http://www.brainpop.com/math/geometryandmeasurement/</a><br /><br />I also think making it relevant to students will help to make it more fun. Use colors and music and draw in the excitement. And be a little silly. It is okay!Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-77025313170121233572011-07-12T05:20:00.000-07:002011-07-24T20:15:32.584-07:001510 Week 5Homework is not the answer!<br /><br />Okay, so there is definitely real value in doing homework. As the old saying goes, practice makes perfect, right? Well, I was reading the blog called "Let's Play Math" authored by Denise. As I read the posts, one follower stated that with the use of new techniques and strategies in math, the parents are the ones learning the homework while trying to help their children with their homework. Denise responded with yes, and that is why at a young age, she is not a fan of homework. <br /><br />I thought that was very interesting. I thought about earlier discussions we had with learning new math strategies and how parents and teachers are so used to learning one way, it can be a challenge to "get on board" with new the new ways. The new ways of learning math should be taught and mastered in the classroom. I do think the biggest challenge with this is time. But time cannot be a barrier to better or at the very least different ways of understanding things like algebra.<br /><br />One of the strategies young students are using to learning about addition, subtraction and multiplication is by using bar diagrams. I think bar diagrams give a clear understanding of numbers and relationships. The blogger, Denise, gives a nice explanation of what a bar diagram is. She says imagine legos lines up. You have the whole part and the parts that make up the whole. <br /><br />There is a website that is used for practice of this technique and helps make learning fun by using an interactive game. The link is<a href="http://www.thinkingblocks.com/ThinkingBlocks_AS/TB_AS_Main.html"> http://www.thinkingblocks.com/ThinkingBlocks_AS/TB_AS_Main.html</a><br /><br />Denise also references a book called Mr Poppers Penguins. This book uses word problems and the bar diagram to solve them. Here is a sample: Mr Popper had 78 fish. The penguins ate 40 of them. How many fish did Mr Popper have left? The problems start out easy and get harder. I think by having a clear understanding of the relationship between numbers helps to make the harder problems using multiplication and division easier.<br /><br />Here is a humorous math clip showing different understandings. <br /><div class="separator" style="clear: both; text-align: center;"><object class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://0.gvt0.com/vi/vU5LoCLGMdQ/0.jpg" height="266" width="320"><param name="movie" value="http://www.youtube.com/v/vU5LoCLGMdQ&fs=1&source=uds" /><param name="bgcolor" value="#FFFFFF" /><embed width="320" height="266" src="http://www.youtube.com/v/vU5LoCLGMdQ&fs=1&source=uds" type="application/x-shockwave-flash"></embed></object></div>Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-47031474498357541532011-07-05T22:27:00.000-07:002011-07-24T20:33:04.813-07:001510 Week 4Finally a topic I like! Factoring. Sorry! Love it! Yes, at times it can be a bit tedious, but I really like it. I am not sure if I really like it because I like it, or if I like it because I actually get it. It might be a little of both. This was a subject that took a lot of notebook paper and well, determination. I had to do a lot of figuring things out. <br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-rBBj_TlTt9Q/ThPtNTfd7MI/AAAAAAAAABA/NPgb5zWV1wo/s1600/math-cartoon1.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="228" src="http://3.bp.blogspot.com/-rBBj_TlTt9Q/ThPtNTfd7MI/AAAAAAAAABA/NPgb5zWV1wo/s320/math-cartoon1.gif" width="320" /></a></div><br />The think that really helped me through this area was the "rules". If you want to see if a number is divisible by 2, just follow the rule. Does 7 go into 65734 evenly? Follow the rules. Here is an example:<br /><br />56743<br /><br />Is it divisible by 2? Well, you could start some long division or grab your calculator. OR ask yourself this question. Is the last digit even? Nope. Well, guess what? The rule says if it does not end in an even number it is not divisible by 2. Go ahead, try it.....<br /><br />Here is another one....Is it divisible by 3? Add it up! 5+6+7+4+3=25. 3 does not go into 25 evenly. So no it is not divisible by 3.<br /><br />Last one, is it divisible by 6? Well, if it not divisible by 2 AND 3, then it is not divisible by 6.<br /><br />Come on......it's too easy and I like it.<br /><br />Here is a little song from youtube. <br /><div class="separator" style="clear: both; text-align: center;"><object class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://3.gvt0.com/vi/K1N4zZndqMs/0.jpg" height="266" width="320"><param name="movie" value="http://www.youtube.com/v/K1N4zZndqMs&fs=1&source=uds" /><param name="bgcolor" value="#FFFFFF" /><embed width="320" height="266" src="http://www.youtube.com/v/K1N4zZndqMs&fs=1&source=uds" type="application/x-shockwave-flash"></embed></object></div>Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-30280695951056745002011-07-05T21:42:00.000-07:002011-07-24T20:13:12.754-07:001512 Week 4G-E-O-M-E-T-R-Y<br /><br />When I think about geometry, I don't instantly think about angles, lines and shapes. I think about middle school. No, not teaching it, but living it. Awkwardly, racing down the the hall from a locker that was way too far away only to realize I was hustling for mmmaaath. No, worse. I was hustling for Geometry. So, I read the cover of my book again to make sure I was still in elementary math, I nodded my head and reminded myself, "Oh that's right, these kids learn way more than I did in elementary math. So, I dug in. The topics weren't too bad and I actually got a flood of memories back, lines, dots, angles and the Pythagorean theorem....yeah...I can do this!<br /><br />HOLD THE PHONE.<br /><br />Preschoolers and kindergarteners learn geometry. Huh? Why? Well a found a really short video that shows you exactly why. This video is from youtube and is actually from Sesame Street. Yes, Sesame Street teaches geometry!<br /><br /><br /><div class="separator" style="clear: both; text-align: center;"><object class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://3.gvt0.com/vi/-9467zZV0Lc/0.jpg" height="266" width="320"><param name="movie" value="http://www.youtube.com/v/-9467zZV0Lc&fs=1&source=uds" /><param name="bgcolor" value="#FFFFFF" /><embed width="320" height="266" src="http://www.youtube.com/v/-9467zZV0Lc&fs=1&source=uds" type="application/x-shockwave-flash"></embed></object></div><br /><br />This little demonstration shows that geometry is indeed relevant and also everywhere! If I think about making a pizza and making sure I cut it correctly to give enough pieces and even pieces. That is geometry. I bought a house a few years back and needed a really tall ladder to be able to paint an area on my vaulted ceiling, all the ladders I was choosing were coming up short. Maybe a little geometry would have helped me to figure out the right size to make sure I could safely reach all the spots I needed to reach. Another area I see geometry used in in art. Oh yes, art. If you think about sketching what is the first thing you do? You start with lines and shapes.<br /><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-YUlOJSldz7U/ThPnYBaw3SI/AAAAAAAAAA8/FtmGo5OfY6w/s1600/drawing-portaits-faces-side.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="318" src="http://1.bp.blogspot.com/-YUlOJSldz7U/ThPnYBaw3SI/AAAAAAAAAA8/FtmGo5OfY6w/s320/drawing-portaits-faces-side.jpg" width="320" /></a></div><br />These are just small examples of everyday life. I have to say, since I have mentioned this before. I am a formula lover. I like to know what to use when. Geometry is full of formulas. So I guess geometry isn't so scary after all. And more importantly it is very important for even young children to learn.Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-69186680350669404352011-06-27T20:47:00.000-07:002011-07-24T20:33:40.457-07:001512 Week 3I am leaving this week a bit frustrated. I find probabilities to be rather confusing. It leads me to ask one question. Do elementary students really do these problems? I am thinking it must be geared more towards middle school. Then again maybe I am just trying to make myself feel better for not getting it.<br /><br />Now, don't get my wrong. I get the importance of probabilities. I think they are an everyday tool, I just think in my head there must be an easier way. I think this is part of my problem though. There isn't a formula you "always" use. It is based on the question. Does it or doesn't it? Regardless, I need more practice and probably should have put in some extra time to try to gain a better understanding of it. And for the students that get this: KUDOS to you! <br /><br />Since I do like formulas, I am going to focus on one. The definition of odds.<br /><br />Odds in favor: A = <u> P(A) </u><br /> 1- P(A)<br /><br />Odds against: A = <u>1- P(A)</u><br /> P(A)<br /><br /><br />These formulas are easy to use and if only they applied to most probability questions, we would be in business. <br /><br />I found this video on youtube that is called the Monty Hall Problem and discusses the probability of opening a door to win a car and what your strategy should be. It gives the mathematical reasoning behind the choice. It's interesting.<br /><div class="separator" style="clear: both; text-align: center;"><object class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://0.gvt0.com/vi/mhlc7peGlGg/0.jpg" height="266" width="320"><param name="movie" value="http://www.youtube.com/v/mhlc7peGlGg&fs=1&source=uds" /><param name="bgcolor" value="#FFFFFF" /><embed width="320" height="266" src="http://www.youtube.com/v/mhlc7peGlGg&fs=1&source=uds" type="application/x-shockwave-flash"></embed></object></div>Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-91633768670221688202011-06-22T15:21:00.000-07:002011-07-24T20:15:45.026-07:001510 Week 3I am consumed with estimations! I feel like I really gained a lot from this last chapter. I always had a good idea of how to estimate something, but it was neat to see so many different ways to figure out a problem. I was always taught the traditional algorithm way of adding numbers and subtracting, like 8 + 10. Put it in the flowing format and solve right to left.<br /> 10<br /><u>+ 8</u><br /> 18<br /><br />But breaking up the numbers like the break apart method where you take a problem like 4 x 28 and break it up into the place values, so take 4 x 20 = 80 and 4 x 8 = 32 then add 80 + 32 = 112.<br /><br />I think this technique is great for not only solving problems in your head, but also for getting a clear understanding of place values and the role they have in math. Here is a video I found on youtube that gives a few examples of multiplying in your head.<br /><br /><div class="separator" style="clear: both; text-align: center;"><object class="BLOGGER-youtube-video" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" data-thumbnail-src="http://2.gvt0.com/vi/dD5ZMoY7HtY/0.jpg" height="266" width="320"><param name="movie" value="http://www.youtube.com/v/dD5ZMoY7HtY&fs=1&source=uds" /><param name="bgcolor" value="#FFFFFF" /><embed width="320" height="266" src="http://www.youtube.com/v/dD5ZMoY7HtY&fs=1&source=uds" type="application/x-shockwave-flash"></embed></object></div><div class="dco"><div class="dco_c" style="padding: 0.6em;"><div class="drt" id="z_o">Doing math problems in my head has never been a strong suit for me. I can do simple math of course, but when it comes to figuring out larger numbers, I am a pencil and paper person or calculator). In the classrooms I observed last year, I spent a lot of time in an advanced math class of fourth graders. I was taken back on how quickly they could compute the problems, many times in their heads.<br />Chapter 3 explained to me how that was done. It seems silly to me that I wasn't taught this way because it not only makes it easier to figure out, but it really explains the "meat and potatoes" behind place values (which is so important). An example of a mental computation is the " Choosing Compatable Numbers Technique". It never dawned on me as a student to try and make the problem simpler and that is what this technique does. Here is an example:<br />(5x6) (30x2) so 5x30 is easy to figure out 150, and 150 x2 is 300, take 300x6 and you get 1800.<br />Another technique that is easy to use is the "Equal Additions Technique". In this technique you change the numbers to make them easier to solve. Here is an example:<br />82-47=? To solve this, you would figure out what changes you can make o the numbers to make the subtraction easier. Well, subtracting by 10 is easy, so if I add 3 to each number (82 becomes 85 and 47 becomes 50) you can make the subtraction much easier. So the new problem becomes 85-50=35, so 82-47=35.<br />Using these techniques can help a student that struggles with math a bit easier and, like I said earlier, it helps to give an understanding to how these numbers work.</div></div></div>Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-15079913566390459742011-06-20T21:57:00.000-07:002011-07-24T20:34:35.589-07:001512 Week 2 postChapter 8 was a brain frying chapter. No, I mean that in a good way. I actually really took a lot away from this chapter. This chapter was on "Analyzing Data". It was a lot of, take this info and tell me a, b and c.<br /><br />The first part of the chapter went over the basics of graphs, like a dot plot, stem and leaf plot, histographs and the classic bar graph. One thing that I found interesting was the difference between a histograph and a bar graph. They look the same, L shaped with vertical columns. The histograph's are side by side and the bar graphs are spaced apart. Our textbook calls it "nonadjacent intervals". Does a graph have a positive, negative or zero correlation? That was pretty easy to recognize. This was not the part that made my brain hurt.....that was the next section.<br /><br />Like I explained in the beginning. The challenge of figuring it all out was a good thing. I have discovered that I am not an "abstract" math learner. I prefer to be told this is how you solve a problem, now follow along and do it. This may bring a further challenge to me as a teacher though because I need to be open to different ways of figuring things out. My husband for example, does a lot of math in his head. When I am working on problems, he peeks over and just blurts out the answer. I have to kindly remind him, "Hey dude, back off. I can't learn that way!" But maybe I should be asking him to show me how he does that. Maybe it would "click" with me and allow me to broaden my scope of teaching. Even if it doesn't "click" with me, it may be helpful and "click" with one of my students down the road.<br /><br />I do like formulas that you can just plug in your numbers. I, however, do not enjoy memorizing them. Something else I have to work on. I feel like I have a good understanding of "mean" - the average "median"- the middle and "range" - the distance between the smallest and largest numbers. Ah the variance. It is tedious work. But having the green box pop up "FANTASTIC!" is so rewarding. I made it and I look forward to the next.....<br /><br />PS Here is a link to enchanted learning with a sample of a worksheet that can be used to teach graphing to students using dinosaurs.<a href="http://www.enchantedlearning.com/subjects/dinosaurs/activities/graphs/gr2.shtml">Enchanted Learning</a>Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-84869874202402673792011-06-20T21:47:00.000-07:002011-07-24T20:37:01.094-07:001510 Week 2 postWhat a chapter, chapter 2 was. One word, YUCK! I spent much of this chapter wondering a few things. What is this "math" all about? Is it really for elementary kids? Why learn this?<br /><br />Ok, let me back up a bit. I realize my introduction may seem a bit negative. I think this intro is similar to many students when it comes to math. Math can be a confusing bustle of numbers, surrounded by formulas, rules and exceptions. It can be hard to keep it all straight. More importantly, if you can't find a link to life with math, then it seems like a drag. So, let's briefly recap what I learned.<br /><br />As I started with Chapter 2, I developed an understanding for sets. Ok, a set is just a grouping of something. I got that. One to one correspondence? Do they align up to another set equally? Sure, no problem. Subsets - come on. Is this group in that group. Zing. A proper subset, sure it's a subset of a given set, but one element is missing from the first set that is listed in the second set. That's a breeze. Unions, intercepts, uh, I can do symbols. A U and a upside down U, not so tough.<br /><br />Next, we got properties. Closure, Identity, Commutative and Associative. I don't recall this from school, but hey, I open to new things. Now, I am a bit of a definition freak. I like them. Give me a word and tell me what it means. Closure property - "For whole numbers a and b, a+b is a unique whole number." (Mathematics for Elementary Students, 2008) Ok, um let's move on to Cartesian product with A cross B. Ohhhh, like 6 x 6 = 36. Not so bad. Let's skip forward to Hindu and Egyptian numerical systems. Oh and let's not forget Mayan and Babylonian. Ok, as weird as this was, I actually felt like I got these down.<br /><br />These examples are just a snapshot of what I have learned. As I pull in the beginning of this post and ask my questions, WHAT? WHY? HOW? I think it is really important for students to understand these questions. As I went through the information, I found that when the book gave examples in "real life" I had a much better understanding of what the definition of a word was and how it does relate to everyday. It made it easier to learn and well, worth learning.<br /><br />Here is a link to a website called Yummy Math. It is designed by some math teachers to help make math relevant to everyday life. <a href="http://www.yummymath.com/algebra.php">Yummy Math</a>Jennynoreply@blogger.com0tag:blogger.com,1999:blog-3704299191811175674.post-23508017679568768202011-06-16T11:10:00.000-07:002011-07-24T20:08:47.695-07:00First timerSo this is my first blog. At first I was a little doubtful on creating a blog. I am not very computer literate and furthermore I don't really like math. But then I started to really think about what I could post on this blog and I am kind of excited. It is a great place for me to post what I have learned so I can share tricks and also have a quick reference to look back on. <br /><br />That's it...I am believer!Jennynoreply@blogger.com0
