In this interactive, students add and subtract plays on a football field to practice working with negative and positive integers on the number line. Each set of randomized drives consists of seven to nine plays and ends with a touchdown. Plays are represented with equations. When students place the football at the correct point for each play, the answer to the corresponding equation is automatically filled in. The accompanying activity suggests ways that teachers can integrate the interactive into the classroom setting. This resource is part of the Math at the Core: Middle School Collection.
