SWBAT find the GCF and LCM of numbers.

Big Idea

Students collaborate on a project.


5 minutes

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.
