Numeracy: Building Integer Fluency provides five challenging, high interest games that build computational fluency with integers. Ranging from simple to complex, these games constitute an indispensable learning aid for grades 3 & up. In its most simple form, MAKE TEN, third graders can make a sum of positive 10 using 2 tiles. Games progressively add operations. In ALL-OPS, upper grade students combine three tiles to result in positive multiples of 10 using any combination of addition, subtraction, multiplication, division, squaring, or square roots. 1-4 players
