About this game

Understand adding one object to a group

Understand adding one object to a group: 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

The object that gets added never appears on screen. Understand adding one object to a group shows a Pre-K child a scattered handful of strawberries, ducks, lemons or balls, from two to seven of them. The instruction, read aloud, says one more is added, and your child taps the new total among four numbers without ever seeing it. Five groups make a round, and every answer is checked and explained: 6 and one more make 7.

Adding one is the bridge between counting and adding. The total is always the next number in the counting sequence, so nothing needs to be counted twice. The hint says it simply: count, then keep counting for the one we add. Picturing that object is the work.

Choosing 6, the number already on the screen, means the added strawberry stayed invisible. Every card offers that number. Put one real object beside the screen and ask, "And this one makes how many?" Then praise the step: "You said the next number."
