## Reflection: Modeling Adding and Subtracting Integers on a Number Line - Section 3: Combining Drives

As an introduction to this section, I showed a short clip of Tom Brady and the New England Patriots driving down the field.  I explained to students that when we add two numbers from the same team, they have two plays where they continue to drive down towards their end zone.

I had a student bring a football to class and we acted out problems.  I explained that unlike real football, we started at the 0 yard line at the beginning of each problem.  During the first Guided Practice problem, I picked a student to play the negative defense.  We acted out each problem in front of the number line.

During the second Guided Practice Problem, I picked two students to act it out and I asked for one student to do the “play by play”.  That student was responsible for talking through the two plays and explaining what happened, who had the ball, where they moved, and where the problem ended.  Students were expected to fill out their notes.  Students really enjoyed acted it out and playing commentator.

# Adding and Subtracting Integers on a Number Line

Unit 3: Integers and Rational Numbers
Lesson 5 of 17

## Big Idea: What happens when you add positive 5 and negative 3? What happens when you subtract positive 2 from negative 3? Students work with a number line and football to model adding and subtracting integers.
