Math Letter Dear mom and dad, I am writing this letter to tell you what we have done in math class. We have studied a lot of subjects in module 1 and I want to tell you about them. We have studied bar graphs, line graphs, number tricks, patterns and sequences, exponents, probability, and order of operations. I will explain three subjects that we learned and hopefully you will understand them. When we were studying exponents we found the area of a cube, the volume of a cube and square roots. We also studied exponential form and standard form. Exponential form is when a multiplication problem is just simplified. If the problem is 5x5x5x5 you could simplify it by doing 5 to the 4th power which is a 5 with a little four right after it. Standard form for the problem above would be 5x5x5x5 and exponential form would be 5 to the 4th power. The little number is the amount of time the first number appears in the problem. When we were studying Probability in class we put a name in a bag and we picked them out one by one and we had to find the probability of what the chance a girl will be pick a chance that a boy will be pick and other chances. We also put three different colored cubes in a bag and we had to decide how many of each color is in the bag based on probability. We did computer simulations about the probability of picking rolling or flipping a certain outcome. We played games that had to do with probability and we created our own game. There are two types of probability and they are theoretical probability and experimental probability. Theoretical probability is what should happen and experimental probability is what does happen. We also learned the order of operations. If is the order you should go in when you have a problem that is complicated. I remember it by using a mnemonic device that is PEMDAS. It stands for Parentheses, exponents, multiplication and division, then addition and subtraction. That is how I remember the order of operations. When we were studying the order of operations Mrs. Harte (our math teacher) showed us a really funny song. That is what we did in math class. These are some things that we have learned in math class. We have learned a lot of new things and have done a lot of fun projects. I hope you like my letter. Sincerely, Your daughter
