About this game

Split a number into two parts

Split a number into two parts: a free Pre-K math game for ages 4-5. Each round draws 5 questions; instructions are read aloud and every answer is checked and explained.

How it plays and why it helps

Sharing strawberries with a friend is a math problem in disguise. Split a number into two parts makes it visible. A Pre-K child sees a scattered group, such as 9 carrots or 10 strawberries, and hears that we give 2 or 3 to a friend. The question, read aloud, asks how many are left. Your child taps one of four numbers. The bank's answers run from 4 to 8, a round has five questions, and every answer is checked.

Taking away is splitting a group into two parts: the part that leaves and the part that stays. Together, they rebuild the whole, which is why this sits next to adding in early math. The hint is a hands-on move: cover the ones we give away with your fingers, then count the others.

Nothing disappears on screen. The whole group, 9, is still there to tap, and it is one of the choices. Cover three with your hand and ask, "Which ones went to the friend?" Then name what worked: "Your hand hid the ones we gave away."
