In Math class my grade has just finished Module 1. It was a good unit with lots of learning and games. We went through some really fun things too. Some of my favorites were our probability unit, computing with exponents, and the order of operations unit.
Our probability unit was fun. We had games that we had played to help us solve probability. One game that we played was putting all of our names in a bag. Then, we pulled out the names one-by-one. The first and the last names got 10 Math points. I was second to last and so close. Every time we took a name out of the bag we would say the fraction out loud. Then when it was just another person and me, everyone stated the probability of who it would be. We also worked on experimental and theoretical probability. We did an experiment on it. I chose to do a project on dice. I would role two dice and take the smaller number away from the bigger one. I would use the sum for my tally. I showed what I thought would happen (theoretical) and what did happen (experimental.)
When we did computing with exponents I really learned a lot. It really cleared up my understanding of exponents. We did a lot of exponent work sheets. For example 5 to the second power is 5 times 5, which is 25. This unit really helped me practice and nail down the technique. We did drills so that we would know how to write in Standard and Exponential form. Standard form is when you take the exponent and and write in regular form (Example = 4 to the 2nd power is 16.) Exponential form is when you take a number sequence and write it as an exponent (Example = 3 x 3 x 3 x 3 is 3 to the fourth power.) This unit was good and very helpful.
The Order of Operations unit was my favorite unit. We learned the order of operation last year, so we reviewed it this year, and learned more advanced things. We learned how to do the order of operations in a fraction. We also earned how to do the order of operations wit exponents. In class we would do fun races in with larger problems. The factions were tricky at first, but once you got them down they became fun. The order of operations is Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. -Otherwise know is PEMDAS. We had a song about the order of operations and PEMDAS, it was really funny.
Overall this Module was good and brought on challenges and fun activities. I hope you enjoyed this letter covering Probability, Exponents, and the Order of Operations.
