About this game

One group in two parts

One group in 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

When the groceries come in, some apples go in the bowl and the rest stay in the bag. One group in two parts tells that kind of story. Sami has 6 carrots, puts 4 in a box and the rest in a bag: how many are in the bag? The picture shows all six. Your Pre-K child taps the answer from four numbers. Each story is read aloud, a round has five, and every answer is checked with a sentence such as 6 is 4 and 2.

Six as four and two is the whole idea. A number can be split into parts and put back together, which children later meet as number bonds. Seeing 9 as 4 and 5 is what makes 4 plus 5 easy one day. The hint is physical: cover 4 carrots with your fingers, then count the others.

Now and then 4 gets tapped, the number heard in the story. It is right there in the choices. Ask, "Is that the box or the bag?" Then point to the effort: "You kept the box and the bag apart."
