Math Letter Dearest Father,

This year in math, I've learned about graphing, probability and the order of operations in Module 1.We've learned how to interpret bar and line graphs, this helps when I'm recording data. I learned to use a bar graph when the data is separated into different categories and a line graph when you have one category of data that changes over time.

We also took information from frequency tables, which we also learned how to make. These tables are made with data that was already taken. The frequency table consist of three columns, one for the subject category, one for the for tallies and one for the frequency. After this we learned how to how to make frequency tables and bar and line graphs we moved on to using variables to solve number tricks.

We used algebra to solve these number tricks. This section in Module 1 was more complicated but it became easy after many worksheets. In Module 1 we also learned how to use sequences, word sentences, tables and graphs. We did many worksheets and math point pages on this subject. Modeling these graphs, sequences, tables and word sentences was not a challenge for me.

Next, we learned to find the nth term of a number sequence, this was some serious algebra. This was very interesting to learn because I havenâ€™t studied number sequences before. Next the powers flowered and we started using exponents in the next section of Module 1. Exponents are a short way of writing a multiplication problem. We wrote both standard and exponential forms in this Module.

When we finished exponents we started learning about probability. We did many experiments with flipping coins and picking little different colored squares out of a bag. I also did a project with my friend on probability. We found the experimental and theoretical probability. We picked jelly beans out of a bag, then we wrote about our results in a paragraph and table. I enjoyed this project because it was really active and I got to eat jelly beans! Our experiment was called Jelly Belly.

The last thing we learned in Module 1 is the order of operations. In Module 1, we learned an easy way to remember the order of operations: PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction). The order goes left to right in the PEMDAS order. I learned a lot of useful and handy information in Module 1.
Sincerley,
