Module 1 letter
Dear Mom and Dad,
I am writing this letter to tell you what we have done for work in math this module. We have learned about graphs and frequency tables to exponents and order of operations. It has been fun and frustrating but, I am learning fast.
The topics I am going to tell you about are frequency tables, probability, and exponents. The first one is frequency tables. Frequency tables are helpful when doing an experiment. The tables also show how many times the variable shows up. The table below is a frequency table:
Type of pet
The table shows that dogs are a more common type of pet than cats and fish.
The next topic is probability. The meaning of probability is a number or fraction ranging from 0 to 1 that tells how likely an event is to happen. There are two types of probability. The first being theoretical probability. The second is experimental probability. Theoretical probability is the outcome that should occur when doing the experiment. Experimental probability is the probability of an outcome from an experiment. The spinner below is an example:
Theoretical Probability: Experimental Probability:
Yellow: ½ Yellow: 1/2
Red: ¼ Red: 1/4
Blue: ¼ Blue: 1/4
The third and final thing I am telling you about is the order of operations. The order of the operations:
Some examples of order of operation problems are:
and many, many more
Now you have had a taste of all the hard but fun math we have done so far this year.
