Sharks and Fish

Before you move on, watch the videos posted below in order to learn how to add and subtract.

You are a shark, living in the ocean, searching for your next meal. You happen upon a school of 20 fish, but you cannot eat them all. You must solve a bunch of math questions to find out how many fish you are allowed to eat. Solve one problem at a time and when you have the answer to that problem that's how many fish you eat. Do this for every problem. When you are done bring your answer to the teacher to see if you were right.
