In these number line games you're asked to make Rabbit jump about a number line so that he lands on the tasty vegetables and avoids the monsters. These activities show how adding and subtracting can be understood as moving along a number line in the same way that children in school use number lines to learn about addition, subtraction, multiplication and division. Rabbit reads out the addition and subtraction calculations that he carries out as he jumps backwards and forwards.

Rabbit Explore Activities
Click on the balloon sign on Rabbit's path to choose the Explore Activities. These are open ended activities where there are no preset goals and children should be encouraged to explore. They are designed to be played by children on their own, with another child or with a parent or mentor. In the explore activities you can create your own puzzles. You can move and change the vegetables, monsters and trampolines already placed on number line as well as adding more of your own.
Explore 1 (left balloon) gives feedback on:
• counting on and back in 2s, 3s, 4s, 5s and 10s
• odd and even numbers
• doubling
• simple inverse operations.
Explore 2 (right balloon) gives feedback on:
• counting on and back in 6s, 7s, 8s and 9s
• multiples of 2, 5 and 10
• inverse operations.
