Part Part Whole
Part Part Whole is an addition game. Your goal is to protect a planet called Sum Total from alien attack. The aliens are angry because their partners are missing. Each alien's spaceship has a numerical value. The value should always equal 100, but doesn't because of the missing partners. Your job is to restore each spaceship's value to 100.
You're armed with a cannon loaded with numbers. Add the numbers on the spaceships with the numbers on your cannon. When the total is 100, fire your cannon at the appropriate spaceship. If your cannon is ready to fire a 10, search for a spaceship with 90 on the front. Fire the 10 at the 90 to get 100 and remove the alien. If you make it past level 3, you work with fractions and decimals.
