About This Sprint

If students haven’t memorized their doubles within 10 facts, they should know the following strategy before doing this Sprint: Show an equal amount of fingers on each hand to solve, e.g. To answer 10 - 5, open both hands before making a fist with one hand. 5 fingers remain standing, so 10 - 5 = 5.
