Determine and explain whether an equation involving multiplication or division is true or false.


Examples


Given the equation 27÷3=3×3 , it can be determined to be a true equation by dividing the numbers on the left side of the equal sign and multiplying the numbers on the right of the equal sign to see that both sides are equivalent to 9.

Clarifications


Clarification 1: Instruction extends the understanding of the meaning of the equal sign to multiplication and division.

Clarification 2: Problem types are limited to an equation with three or four terms. The product or quotient can be on either side of the equal sign. 

Clarification 3: Multiplication is limited to factors within 12 and related division facts.

Lesson Plan

Name Description
Arrays Show the Way to the Multiplication Chart

This is an introductory lesson to explore the use of arrays to solve multiplication problems. Students build arrays and save the arrays in a class Multiplication Chart. They learn to use arrays to find products and factors, and by placing them in the Multiplication Chart, they learn how to read the chart. They learn how to write equations to represent situations that are modeled with arrays. An overall theme is the organization of the multiplication chart and how it includes arrays within.
