##### This Squeebles Addition & Subtraction app also includes:

The math monster is at it again, this time stealing all the cars and drivers that were to take part in the cart race. If their addition and subtraction facts are up to the challenge, young mathematicians can win the drivers' freedom and play in the big cart race.

##### App Overview

Squeebles Addition & Subtraction is another app in the Squeebles series of apps that encourage fluency in basic math operations. As with most of these apps, young mathematicians are rewarded for successful math practice. They earn badges that are needed to unlock the game. Here, they earn stars to trade in for Squeebles carts. Getting a certain number of total questions right earns your Squeebles' rescue. Once players earn a cart and a Squeeble to drive it, they can play in the cart race.

##### Instructional Ideas
• The difficulty levels can be used to help more beginning students feel successful and challenge advanced learners
• Have players save all their earned carts and Squeebles for a big addition & subtraction race day. Players can form small groups to compete with each other and then put up the best cart from their team to race against other teams.
