Subtracting Integers

Students investigate how to subtract integers using a number line. On the last slide students can practice with an infinite number of questions. It was based on the description of subtraction with a number line on pg 12 of the Integers Gap Closing resource. Note that you could just as easily do this activity without technology. However, in this version, the last slide will randomly generate a bunch of questions for kids to practice with.
