Lesson Title	Interpreting and Factoring
Unit Title
NRS Level	Level 3
Length of Lesson	60 minutes

Lesson Purpose

To reinforce the concepts of multiplication and division through comparing and deconstructing mathematical products and their dividends/divisors and multiplicands/multipliers

Lesson Objectives

At the end of this lesson, students will be able to:

· Interpret a multiplication equation as a comparison.

· Find factor pairs for numbers to 100, and use understanding of factors to define prime and composite.

Student Target

“I can factor and compare numbers to model multiplication and division.”

CCR Focus Standards

Algebra and Functions - Level C

4.OA.1
Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 x 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.

Supporting Standards

4.OA.4
Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite.
