Do you want to color the tractor? It’s easy! Solve the subtraction questions, drag the answers to the correct places, and the tractor will soon become colored. When the teacher wants to know how well the pupils subtract, all he/she has to do is check how much of the tractor each pupil has colored.

Missing numbers up to 20 swim in the water with fish. Can you find them all? You have to solve three sets of 12 problems, which are changed when the math game is reopened.
