Multiplication strategy #3 – using 1s, 2s, and 5s. the decomposed array strategy leads right into the next strategy. for this strategy, the students use their known facts (usually 1s, 2s, and 5s) to solve unknown facts. here you can see that the 8 x 4 can be solved by decomposing the 8 into 5, 2 and 1 and solving (some students may do 5s and. This strategy builds on the strategy for multiplying by 2 and 4. students double the initial quantity. then, they double that quantity. finally, they double the resulting amount. for example, if you want to multiply 7 x 8, double 7 to get 14. then, double 14 to get 28. finally, you double 28 to get 56; therefore, 7 x 8 = 56. So that is one more strategy you can use. we also solve two word problems using estimation (instead of using long division, which could end up being more cumbersome). this is meant for 4th grade math and on up, as many math curricula never teach strategies for rounding and estimating, or how estimation can be used to solve word problems.

Introduction to multiplication strategies teaching slides introduce your students to different multiplication strategies such as arrays, equal groups, repeated addition and skip counting with this 34 page slide deck. Let's build a solid foundation of multiplication so we will be ready to multipy 1 and 2 digit numbers in fourth grade! in this unit, we will practice using equal groups, number lines, groups of objects, and array to multipy. to wrap things up, we will use the associative property, distributive property, and commutitive property to better understand multiplication.
