Is your amateur skier ready to shred that mountain? It's not her athletic abilities, but her subtraction skills that will help guide her character down the slopes. For each single-digit subtraction problem correctly solved, her character will grab some air and get one step closer to the bottom. After a few times down the course she'll have memorized basic subtraction facts, and maybe even be first to cross the finish line!
