7th grade · Ratios & Proportional Relationships
Explain what a point (*x*, *y*) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, *r*) where r is the unit rate.
3 interactive, auto-graded activities for 7th grade students practising 7.RP.A.2d. 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.
This is a sub-standard of 7.RP.A.2.
In this hands-on activity, students use equivalent ratios to scale down real-world park dimensions and see their design come to life in an automatically generated graph. As they convert measurements, complete ratio tables, and analyze the final layout, they build fluency in proportional reasoning and visual interpretation.
Students explore graphs of real-world proportional relationships—like taxi fares, printing costs, and song downloads—to interpret points and identify unit rates. With minimal reading and strong visuals, this activity builds deep understanding of coordinate graph meaning.
In this real-world math activity, students apply their understanding of ratios and fractions to convert Grandma’s recipe from kitchen units to standard grocery store units. Using a conversion chart and price list, they calculate the quantity and cost of each ingredient, determine the total expense for 25 cookies, and find the cost of one cookie.
