Review the goal “Find the missing number” in Grades 1–3 math (ages 6–9). Its questions are additions with a missing number, like □ + 2 = 5.
This review game covers a math goal for the first three years of elementary school: “Find the missing number”. Its questions are additions with a missing number, like □ + 2 = 5.
Each round has 8 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 6 to 9. Play it again for different questions.
Try your number in the equation: if 3 + 2 really makes 5, you are right.
