This is how they are teaching in the schools I have been in. Great math hack for your kids! I wish I knew this in elementary school. I don't teach multiplication any more this is a great idea for those few facts kids just have a tough time memorizing.
An Apple For The Teacher: My Students are Kicking Their Math Facts & Learning Them Too! Fun and motivating way to help students learn their math facts! Could be done with addition/subtraction for younger kiddos.
