About Subtraction Race

Subtraction Race is a free practice game for kids who are building subtraction fluency. Each level adds a little more challenge: differences within 10 at first, then within 20, 50 and finally 100. Children answer subtraction questions to push their runner toward the finish line before time runs out.
