Subtracting Integers

When I Googled videos about subtracting integers, every one had a teacher lecturing how to do it.  We decided to create four videos that would allow for students to see real subtraction problems of integers.  They needed to determine the "take away" problem and how it changes to an addition of the opposite.  We consider it a small case of problem based learning!

See the vidoes!

Our students using the videos for discussion of subtraction of integers!
