What a great way to think about subtraction! This online game has an escaping convict, flashing search lights, and a police siren that sounds when you’ve answered the problem correctly. The game teaches children to find the difference when subtracting by using a numberline. Figure out the distance the convict goes from his jail cell by answering the subtraction problem. In steps you move from the subtrahend, the number being subtracted, to the next 10, then move in 10s, and on the target number. Write your answer, check it, and catch the criminal.
