8th grade · Functions
Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
3 interactive, auto-graded activities for 8th grade students practising 8.F.A.1. Mini Labs put the standard to work in a real scenario; Skill Practice builds fluency on the standard alone. Every one is randomized per student, so each learner gets their own numbers.
Analyze real physics experiments using linear functions in this interactive worksheet. Students graph given functions for robot motion, battery drain, and battery charging, then interpret slopes and intercepts in context. Aligned to CCSS 8.F.A.1, this activity builds strong intuition for functions through meaningful graphs and real-world data.
Analyze real-world warehouse operations by graphing given linear functions in this interactive worksheet. Students create tables, plot ordered pairs, and interpret slopes and y-intercepts for orders processed, inventory remaining, and fuel usage. Aligned to CCSS 8.F.A.1, this activity builds strong graphing and function interpretation skills through a realistic e-commerce storyline.
Labs run 2 to 4 class periods and connect several standards into one project.
Curbside is an interactive Grade 8 math lab where students run a food truck and use real math to decide if it makes money. Across 7 auto-graded worksheets they build revenue, cost, break-even, and profit, compare competitors, and weigh a marketing curve. A hands-on way to make expressions, equations, and functions feel real. Common Core aligned (8.EE, 8.F).
