Defining Factors and Factor Pairs
Property
Factors are numbers that are multiplied together to get a product.
If , then and are factors of .
The set is called a factor pair of .
In this Grade 4 enVision Mathematics lesson from Chapter 7, students learn how to find factor pairs of whole numbers by building and analyzing rectangular arrays. Using grids and multiplication, students discover all the ways a number can be decomposed into two whole-number factors, practicing with numbers like 12, 16, 36, and others. The lesson connects array models to factor pair notation, building foundational skills for understanding factors and multiples.
