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).

Mayday, mayday! Muggo's fleet is in trouble. Fifth graders must calculate the product of smaller arrays to help Muggo's ship get back on course. Great for visual learners, this array game shows students how to determine the product of two-digit multiplication problems by dividing the area of a grid into smaller arrays. Practicing these skills help kids move from concrete to abstract problem-solving in multiplication.
Architects on the ready! Practice finding the area while giving kids the opportunity to build a pool in this hands-on math game. Kids will love having control of the game and letting their imaginations run wild while creating a pool with a set area. Follow-up word problems help kids take their backyard design a step further while using multiplication to answer questions about area.
Every good scientist needs to learn how to work with decimals. Your fifth grader can level up from regular multiplication to multiplying decimal numbers in this challenging game that helps Penelope with a science experiment. Each time your child completes an equation correctly, Penelope's beakers will fill to the amount in the answer, providing a handy way to visualize decimal numbers.
