Subtraction Game For Kids: How Many Under The Shell
Join Okta, a smiling octupus, in the fun online subtraction game for kids How Many Under The Shell.
After Okta hides some bubbles under a shell, he then either adds more bubbles or takes some away. Kids have to determine how many bubbles are still left under the shell.
This free subtraction game is a part of the website Illuminations, which hosts lots of great resources for teaching maths.
The octupus will teach children addition and subtraction.
