Week of November 13-17

This week, some third graders learned about the difference between gross profits and net profits. They calculated the net profit of Pixar and Dreamworks movies by subtracting the budget from the gross profit. This will help us figure out which company is doing better financially. We also learned what it means to be "in the red." Soon, we will put all of this data together to decide which company to work for!

This student is calculating the net profit of recent movies.

In 4th grade, we revisited the question: what makes a game fair? We realized that in order for a game to be fair, each play must have the same theoretical probability of winning. Students were then given the challenge of creating their own carnival game based on chance that is slightly unfair (carnival owners have to make a profit)! They must be able to prove that the game is unfair by calculating the theoretical probability of winning and losing. I can't wait to see what everyone comes up with!

In 5th grade, we finally got some of our video game elements to move! We definied functions that take in the danger's and target's x-coordinate and either add or subtract 50 in order to move it left or right. Now, the problem is that they fly off the screen and don't come back! Our next challenge will be to keep them onscreen!
