This fun Fact Family Home will help children understand the concept of "fact family" (2 additions and 2 subtractions that use the same three numbers) as taught in grade 1. An example: Numbers 2, 3 and 5 make the following: 2+3=5, 3+2=5, 5-3=2, 5-2=3. 
Perfect for helping those little minds grasp concepts by using various senses and movement of pieces (also great for fine motor skills). Comes with 5 of each number and the fact family home.
