The integer timeline can be used as a project while or going after number sense (integers). It is targeted for sixth grade but can be modified to use with fifth or seventh graders. The project is complete with a description, checklist for students, a rubric, a premade timeline to help students who struggle creating their own, and an example timeline to show students.
