This lesson has everything you need to teach a "Thin Slicing" lesson on writing linear functions from a graph for 8th grade math. These progressively challenging task cards start students with simple proportional graphs and progress up to writing a linear function from line graphs where the y-intercept is not visible. 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 instructions on how I run a "Thin Slicing" lesson using Vertical Non-Permanent Surfaces (VNPS) in my own classroom.
• 13 Full-Size Task Cards on writing linear functions from a graph.
• Answers for all Task Cards.
• "Notes To My Future Forgetful Self" Student Notes Template.
• Student Notes answer key.
• "Check Your Understanding" student Exit Ticket.
• Exit Ticket answer key.

Once the thin slicing lesson is complete, students can use the provided notes template to record their thinking, as well as complete a "Check Your Understanding" exit ticket to give you and your students formative assessment feedback on how they are understanding the topic.
