8th Grade: Meaning of Slope Activity

The 8th Grade worked on several iterations of a tricycle racing problem. They used clues from the problem to determine different lines. Using graphing skills and systems of equations, they found out who won.

I've taught that unit many times, and was impressed on how CPM Algebra Connections builds an understanding of rates of change before just throwing "slope is rise over run" at them. It takes some patience, particularly with students who have already been introduced to slope from previous teachers, but I thought it was worth it.

I agree. Patience, patience, patience. The RISE over RUN issue is huge. I ask my students what slope means and that is what they answer, even when I have never mentioned it!
