CCTM 2014: Beyond Rise over Run: Activities to invent and connect slope's five faces

Slope has five—count 'em, five—faces. Students shouldn’t focus on just one or two, and in this session, neither will we! Instead, we'll explore realistic and meaningful activities and a learning progression designed to help students invent and make connections between all of slope’s five faces. 
(This is a shortened version of the session I facilitated at NCTM 2014.)
