This is a task on the rate of change and slope triangles.
This is a Team Task on Slope Triangles and Stacked Boxes. The Team Task includes critical thinking and is scaffolded with color-coding. The students will take turns as Team Mathematician and determine the rise and run of the given two triangles on the task using a Stacked Boxes diagram. As the students measure they color-code the given diagrams to find the slope of the line.
*** My "Team Tasks" are created to be completed in Teams of four. Each student is a team member: Team Member (A), Team Member (B), Team Member (C), and Team Member (D). Each team member is required to participate regularly throughout the "Team Task" as Team Mathematician. My cooperative learning "Team Tasks" require the students to be actively involved throughout the entire "Team Task". The Role of "Team Mathematician" alternates throughout the "Team Task". My "Team Tasks" are designed to elicit mathematical discourse within the teams.
Included are blackline masters of the "Team Task", and blackline masters of the Stacked Boxes Diagram.
