Math Resources May 6, 2013 By Bekki Leave a Comment This content may contain affiliate links. Here are some of my favorite Math Resources. My Math Resources can be found here: These are triangular shaped flash cards. I love them because they contain complete fact families. One addition card may contain the numbers 12, 9, and 3. your child learns to associate all three of these numbers together making it a cinch to know 3+9=12, 9+3+12, 12-9=3, and 12-3=9 Math Dice! OK, my kids LOVE rolling the dice. Throw these together with Yahtzee and you have hours of math fact practice! Math drill sheets click here Great Math Games!
