Week of October 10-14

This week, the 3rd graders continued to explore ways to find irregular area. We learned a method that involves decomposing a figure into rectangles, finding the area of each one using the length times width formula, and adding the areas together to find the total square units. We also learned to count whole and partial squares and add them together.

In 4th grade, we solidified our understanding of the difference between theoretical and experimental probability. We now know that theoretical probability is the number of favorable outcomes over the number of possible outcomes. It is not dependent on the number of trials. For example, on a dice, p(1)= 1/6 because there is one favorable outcome out of 6 possible outcomes. Experimental probability is the number of times an event occurs over the total number of trials. According to the Law of Large Numbers, the more trials we do, the closer experimental probability will get to theoretical probability. 4d also explored systematic ways to find all possible outcomes of a situation.

The 5th graders continued to learn new functions to create images and to combine images. Ask your child to show you how to use overlay to make a picture! 5d started to learn how to define functions in order to be more efficient. I am so impressed with how quickly the students are picking up on all of this new info. We have lots of future programmers on our hands!
