Dear Mom and Dad,
We just finished Module 1 in our mathematics textbook. There were a lot of worksheets and problems to solve.
First, we learned how to make frequency tables. Just tally the amount of times something happened in one column, and then write the number of tallies in another. To make a frequency graph, just make a sideways bar graph. We did several pages in the book where we had to answer questions based on a graph. We also learned when to use a line graph and when to use a bar graph. You use a line graph to show changes over time and you use a bar graph when you are putting things into categories. We even took a take home quiz where we had to answer several questions using a graph we found in the news paper.
Next, we moved onto probability. I worked on a project where I picked Gummy Bears out of a bag, then made a table to show experimental and theoretical probability. Experimental probability is what happened in the experiment. The theoretical probability is what was supposed to happen in the experiment. We also did experiments with spinners and dice to show probability.
After probability, we studied number patterns. Our teacher showed us all kinds of cool number tricks that seemed unreal. We used algebra to show how the tricks worked. We also used algebra to show the relation from term to term number in a table, so we could find the nth figure. Once I got the hang of it, the problems were very simple to solve.
Then, we studied order of operations. Our math teacher played us a funny rap about PEMDAS. P for parentheses, E for exponents, M for multiplication, D for division, A for addition and S for subtraction, you can call it PEMDAS! It was awesome. We did some worksheets. To go with that, we learned how to calculate exponents. At the end of the Module, we had a big test.
