Teacher To Teacher: A Videotaping Project to Explore the Multiplication of Integers
My eighth-grade mathematics class was having some of the usual difficulties with beginning-algebra concepts. Because the students were becoming somewhat frustrated, I was looking for a way to present the multiplication of integers so that student could readily understand the concept. Relating this idea to the distance formula, which we had already tudied, would not only help put this idea into a more familiar context but also would review a formula that the students would often be using the next year in first-year algebra.
