Week of October 17-21

This week, we continued to work on finding the area of irregular shapes. We watched THIS video on how to cut off pieces of irregular shapes and reattach them to form a regular shape like a rectangle. Then we can use the formula for finding area (a = l x w) to calculate the area of an irregular figure. For more practice on this concept, try some of the activities in THIS slideshow.

In 4th grade, we learned systematic ways to find all possible combinations or outcomes of a situation. We made tree diagrams, systematic lists, and used multiplication to find the number of total combinations. Can you figure out this challenging problem?

Four different coins are tossed one at a time. How many different combinations of heads and tails are possible? List them. (Hint: use a tree diagram). Check out THIS video if you need help.

The 5th graders learned how to define values and functions in their programming language. We talked about how defining values and functions allows us to write code that is more efficient. We also learned how to use variables when defining functions (like if we want to make green triangles of different sizes or to make circles of different colors). Ask your child to show you what he/she can do in wescheme!
