Grade 8 Functions Complete Unit | 12 Lessons | 8.F

A complete 14-day unit for Grade 8 Functions, grounded in the Class Roller Coaster Design scenario. Every lesson connects to the same authentic context, so students see how 8.F skills work together instead of as disconnected topics.

Every lesson connects to the class designing a roller coaster track - identifying that each distance has exactly one height (function definition), using the vertical line test on track shapes, evaluating height at specific distances using function notation, comparing two coaster designs, distinguishing linear (straight ramps) from nonlinear (curved drops), building linear functions from track data, and describing each section qualitatively (climbing, plateau, falling, climbing again). Students see how 8.F skills come together to plan a real engineering project. The 12th lesson and summative performance task bring it all together.
