See how many addition and subtraction problems you can get right. God for finding missing numbers in sums
Okta challenges you to a duel! That crazy octopus wants to play you in a game where the first person to choose cards with a specified sum wins. You can choose how many cards, what types of numbers, and Okta's level of strategy.
See how many shots you can make in the time limit! A missing addend/subtrahend/factor arcade basketball game.
Alien Addition is a math game that helps students with learning addition using an alien invasion theme. Invading spaceships with addition problems move down from the top of the screen toward a laser cannon on a platform at the bottom.
Glowla has created this weird machine just for you to play with! Here's the deal: The machine will show you a bunch of numbers. You need to type in an estimate of what those numbers would add up to.
This is a match 3 game with a mathematical twist. Your goal is complete each level by changing all gray tiles to yellow. Each balloon has a statement in it about rounding numbers. Determine if the statement is true or false.
