About this game

Find what is missing

Find what is missing: 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

Ask a child how many more they need and you can often watch the fingers come out. Find what is missing turns that moment into a Pre-K game. Sami has 3 carrots and wants 7; Leo has 2 lemons and wants 6. The picture shows only what each child already has. Your child taps how many are still needed, from four numbers. A round has five stories, each one read aloud and checked.

The skill is a missing part: knowing a start and a goal, and finding the gap between them. The hint suggests counting the carrots, then going on with fingers up to 7. That is counting on, and the raised fingers hold the answer.

Counting on has one classic trap. Starting at 3, a child often says three again on the first finger, ends with five fingers up and taps 5, which is among the choices. Try it together, out loud. Ask, "Which number do you already have?" When the fingers come out right, say so: "You started after three. That was the trick."
