This review game covers a math goal for Pre-K and Kindergarten: “Understand that an amount stays the same when the objects are moved”. Its questions spread objects out without adding or taking any away: you say whether there are still as many.
Each round has 5 multiple-choice questions drawn at random. The instructions and answers are read aloud, and a bar shows how far along you are. After each answer, an explanation helps you understand. Hints are free, and you can go back.
The game is for children aged 4 to 6. Play it again for different questions.
