Third grade is the year of multiplication. Though it was most likely introduced to kids in second grade, third grade is when kids are tasked with mastering their times tables and developing a stronger understanding of this key operation. This guided lesson in understanding multiplication can help give third graders a leg up. For even more practice, consider downloading the recommended multiplication worksheets that accompany the lesson.
This year, second graders will be introduced to the concept of multiplication using repeated addition. For example, they will learn that 5+5+5+5+5 is the same thing as saying 5x5. This guided lesson will use manipulatives to teach kids about repeated addition and give them plenty of opportunities to practice addition within 100. Download and print the accompanying worksheets for even more addition practice.
There are many strategies that can be employed to multiply and divide larger numbers. Students will deepen their conceptual knowledge of multiplication and division, starting with visual models like arrays and diagrams.Then students will then move to more abstract calculation methods like partial products, the distributive property and standard algorithms.
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).
