This super-fast paced game requires students to ski through the gates that complete an equation, but to avoid those that make the equation incorrect. For example, if a student chooses x 8 to practice, he or she would ski through gates that show 2 and 16, but around gates that show 4 and 30. The game is customizable and allows players to choose the operation and the specific numbers.
