MA.4.AR.2.1

Export Print
Determine and explain whether an equation involving any of the four operations with whole numbers is true or false.

Examples

The equation 32÷8=32-8-8-8-8 can be determined to be false because the expression on the left side of the equal sign is not equivalent to the expression on the right side of the equal sign.

Clarifications

Clarification 1: Multiplication is limited to whole number factors within 12 and related division facts.
