When working with integers, I always have a group of students who catch on quickly and need a challenge. This is a great extension activity for students who understand adding and subtracting with integers and are ready to explore it with fractions. I included a number line so students can model movement on the number line. Based on your class, this could serve as a homework assignment, in class activity or extension. You could also use this as an interactive notebook page!
I uploaded this as a Word document so you can make changes to better fit the needs of your students.
