## What is Two Stars Basic?

Two Stars is a highly explosive math game that helps you to train speed in addition. You have to combine number stars to make sums of 10.

"Make Ten" is a basic principle for addition within 100. For example: 8+7. How many more are needed to make 10? 2! If the 2 is taken from the 7, how many are left over? 5! So, 8+7 is 10+5, or 15. This principle is also used for addition of bigger numbers, such as 38+7. Two Stars lets you develop this key strategy in addition. It helps you to see parts that numbers consist of and to combine them, so addition becomes something you make easy and cool.

This version has 3 levels only.
