# GCF and LCM Project, Day 2

Lesson 6 of 10

## Objective: SWBAT find the GCF and LCM of numbers.

*40 minutes*

#### Introduction

*5 min*

I will remind students of the expectations I have of them:

1. Work together

2. Respect each other

3. Stay on task

On day 1 of the project, students should have completed the problem individually and discussed their work and answers with their group. The focus of today is for groups to agree on a method and work to display on the chart paper. Then they will work together to complete the poster.

I will remind students that all of their work should be on the poster, but they shouldn't include their final answers. Since this is the last day to complete the project, I will frequently give students time checks.
