This mental math game help students practice subtracting numbers up to 10. Students can play the game several times because subtraction facts are never the same.

All the wrong answers must be corrected if students want to help the mouse through the math maze.

Students can measure how much time they need to complete the task, and they can see if their subtraction skills are improving.

By looking at the mouse position at the students' screens, the teacher gets an immediate insight into how well they subtract.
