This review game covers a math goal for the first year of elementary school: “Two ten frames”. Its questions show two ten frames, one full and one partly filled: you say how many dots there are in all, from 11 to 20. Others ask you to type the missing number: 10 and 7 make 17; 17 is 10 and 7.
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 6 to 7. Play it again for different questions.
