About this game

Count on to 10

Count on to 10: a free Kindergarten math game for ages 5-6. Each round draws 5 questions; instructions are read aloud and every answer is checked and explained.

How it plays and why it helps

Some children count a whole row again even when its number is printed right next to it. Count on to 10 is a Kindergarten game that gives them a reason not to. Two rows of boxes are shown. The top row's number is given, and the bottom row has one more object, carrots or dolphins, for example. Your child types how many are in the bottom row. Five pictures make a round, read aloud, and each answer is checked and explained: 3 and one more makes 4.

Counting on means starting from a known amount and counting only what is added. It is faster than counting all, and it is the first real strategy for addition. The hint says it plainly. Start from the number, then count the ones that stick out.

The two rows look nearly the same length, so the top row's number is a frequent answer. Cover the top row with your hand and ask, "What number is under my hand?" Then point at the extra one. Praise the move: "You started from the number."
