This is a cool Math learning and practice app for children for learning single digit subtraction. A Magic Tortoise gives different problems and guides the child. It points out mistakes (like wrong subtraction etc.), monitors child’s progress and increases the complexity of problems as child becomes better. It also teaches the child subtraction, elaborating step by step by counting sticks in an animated way when child can’t solve the problem. The child can touch the Report Card icon to see the progress.
