## Reflection: Developing a Conceptual Understanding How To Easily Find All Those Factor Pairs - Section 4: Assignment: Graph paper, arrays and factor pairs

Students really enjoyed using the Factorize website and using visual models to find their missing factor pairs. Solving factor pairs feels like a puzzle or a game. Students fluent in their multiplication facts could also get a very concrete understanding of how the array model supports understanding factor pairs. The standard is very precise about learning to list factor pairs to 100, but I am hoping they can be more fluent through this understanding of both divisibility and through arrays. As I instructed, I built upon concepts and then let them practice. The Factorize interactive website was a cool way of helping them see how to create the array and find the missing factor. They could then transfer this concept to paper independently. This video shows their homework success and is a sample of those first steps toward mastering the standard. After they practice more they will be able to extend and apply strategies to find factor pairs to 100.

Colorful fun understanding...leading them to mastery of the standard.

# How To Easily Find All Those Factor Pairs

Unit 4: Concepts of Multiplication
Lesson 2 of 12

## Big Idea: Students learn to list factor pairs through the use of a dynamic website that uses grid lines and a listing strategy. They will discover how to find the missing factor of those factor pairs ( basic facts) that they don't know through using arrays.
