Look at these bunnies! They make a number line from 0 to 10 to help you add. For example, in 1 + 3, find the bunny with the first number, 1. Then hop to the right, counting the number of bunnies you pass. Stop when you reach the second number, 3. Do you land on 4? Perfect! That's because 1 + 3 = 4. Now hop away and finish the activity!
