About this game

Put two groups together and count them all

Put two groups together and count them all: 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

Some of the fish are in a basket nobody can see. That is the twist in Put two groups together and count them all. The screen shows a scattered group, say 5 fish, and the instruction, read aloud, adds the rest: there are 4 in the other basket. Your Pre-K child taps the total from four numbers. Totals run from 5 to 10, a round has five questions, and every answer is checked.

Hidden amounts are hard to add. That is the point. Fingers or a counting voice have to stand in for the hidden fish, which is the start of thinking about numbers rather than things. The hint shows the way: count the fish you can see, then keep counting with the other basket.

The number your child hears, 4, is also among the choices, and some children tap it straight away. Hold up four fingers for the basket and ask, "Where are the other fish?" Then name the strategy: "You counted on with your fingers."
