Comparing Linear Functions BTC Thin Slicing Group Activity | Grade 8 Math

This "Thin Slicing" activity on comparing linear functions gets your 8th grade students thinking about linear functions. These progressively challenging task cards start students with simple proportional relationships and progress up to writing a linear function from only two ordered pairs, graphs with differently scaled axes, and tables with minimal information. Students must work together to compare rates of change and initial values for multiple functions, including tables, graphs, equations, and scenarios.

Great as a review activity, or as an introduction to comparing linear functions after your students have learned slope-intercept form.

This lesson with printable task cards uses Building Thinking Classrooms strategies for teaching math created by Peter Liljedahl. If you have been looking to implement the Building Thinking Classrooms model of instruction, but don't know where to start, this is a great resource for you.

 This lesson includes the following materials:

• Complete lesson instructions for how I run this activity in my own classroom.
• 8 Full-Size Task Cards on comparing linear functions.
• Answers for all Task Cards.
