Showing Results for arrays

Use this exercise to teach your students concrete strategies to multiply two-digit factors: base ten arrays, area models, and partial products.

Three Ways to Multiply

Multiplication is essentially repeated addition, or growing numbers by doubling, tripling, quadrupling, and so on. This unit presents mental models and strategies that help students learn and review the concept of multiplication. Students explore multiplication using arrays, partial products, doubling methods and the standard algorithm to solve numerical and word problems. Students will multiply whole numbers and simple decimals by base ten exponents (i.e. .3 x 103).
