Letter to Mom
In math class we are learning about many useful things. In the beginning of the module, we learned mostly about graphs. We learned about how to graph data, construct graphs, and how and when to use a frequency table. We also learned what the difference is between the the two graphs and which one to use at the appropriate time. You use a bar graph when you are graphing data from a survey or pole and you use a line graph when you are graphing data over a specific time period.
We also learned how to make a model sequence with word sentences, tables, and graphs. This unit was mostly about turning sentences into tables and graphs. It was pretty easy.
After that we learned about using variables to solve number tricks. Using variables can make problems so much easier. We also learned how to predict the nth term in a number sequence (example: T=n+4-2 so the 15nth term is 17).Learning variables helped a lot with that.
Next we learned about computing with exponents. We had done this last year so it was the easiest for me and we spent the least time on it.
Then we learned about probability. We learned about experimental and theoretical probability and about estimating probability using 0 through 1 (example: 1/3). We did a project on this last week. I worked on it with my friend. My friend and I put 50 star burst’s in a bag. We put a certain amount of each color and recorded the theoretical probability. Then we picked out of the bag a certain amount of times and then we recorded the experimental probability.
The last thing we learned was the order of operations. In order to do this right all that you have to know is P.E.M.D.A.S. This stands for Parentheses Exponents Multiplication and Division Addition and Subtraction. We have been having a lot of fun in math class this year.
