Unit Title
NRS Level	Level 1; Level 2;
Length of Lesson	60 minutes

Lesson Purpose

To introduce numerical value comparison ahead of more complex activities so that students can identify similarities and differences in value

Lesson Objectives

At the end of this lesson, students will be able to explain the meaning of the equal sign by pairing equivalent expressions and constructing true number sentences.

Student Target

“I can compare number values to create number sentences.”

CCR Focus Standards

Number and Ratios - Level A

1.OA.6
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

Supporting Standards

1.OA.7
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
