 Math Letter I just got done learning all about Module 1 in my math class! I have learned so many cool and important things in this Module. One of the many things I’ve learned about is bar graphs and line graphs, and when to use them. Did you know you use a bar graph when you need to display different categories? Also, you use a line graph to display information over an amount of time. Learning about graph was one of my favorite things about this module because I caught on quickly and it was easy for me to learn. Another thing I learn in this Module is, how to make a frequency chart. I loved using the frequency charts because it helped me a lot with my probability. It was always fun using this chart. For example, say I had a wheel and the colors on this wheel were blue,red, and green. Now say I spin this wheel 20 times and come out with the results, 5 for red. 10 for blue, and 5 for green. I would make tallys on my chart and then after I was done. I would have a section on my chart labeled frequency, in that section, I would write down the number of tallys and the number of times I did it. Such as this: 5/20 Guess what else I learned! I learned about one of my favorite things, PROBABILITY! I worked a lot on this part of Module 1, and it was my favorite part. Some of the things I learned in this part was how to determine the experimental and theoretical probability. Which isn't as hard as it seems. You see, for theoretical probability all you have to do is list the number of the item you put in the bag and how many things are in the bag. For example, I put in 10 cards in a bag, I put in 3 red cards so I would write it like this : 3/10. For experimental probability it's very similar. I'll explain it through example. Say I have the same bag with the same 10 cards. Inside that bag there are 3 red cards and 7 black cards. I make a frequency chart and pull cards out of the bag 20 times. I pull out a black card 15 times, so the experimental probability would be 15/20. Also, I learned about Algebra. One of the things we learned in this part is how to identify the rule of a sequence of numbers or patterns. For example, If the pattern is 1,4,9 the rule would be T=N2. I got this by looking at the term number and then the pattern. The last thing we learn about was the order of operations, other wise known as PEMDAS or Please Excuse My Dear Aunt Sally. The order of operations consists of parentheses, exponents, multiplication, division, addition and subtraction. You go in order except for multiplication, division, addition, and subtraction. For those you go from left to right. Order of Operations was probably the easiest for me to learn because I love getting to the bottom of math problems.
