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.
(can use the same idea to show multiple ways of adding/subtracting) GREAT!-- multiplication unit to teach repeated addition, groups of, commutative property, and arrays. You could also replace one with a multiplication word problem and picture.
