![]() Reinforce the 3’s multiplication facts with this set of task cards. In this case, they can think, “the double of 5 plus one more group of 5,” to make 15. ![]() For example, if students are faced with an equation like 5×3, they can still use this strategy since 3 is one of the factors. This means that the order of factors does not change the product. It’s also very important to reinforce the commutative property. ![]() Students can think of a 3’s equation as “the double plus one more group.”įor example, to solve the equation 3×4, think, “the double of 4 plus one more group of 4,” which equals 12.įor 3×9, think, “the double of 9 plus one more group of 9,” to make 27. The 3’s multiplication facts use students’ knowledge of the doubles addition facts. ![]()
