About this resource
A complete three-day mini-unit on ratios and unit rates using recipes, prices, and speeds. Students move from ratio language to ratio tables, double number lines, tape diagrams, unit rates, and recipe scaling, and finish with spot-the-mistake, word problems, and an exit ticket.
The Teacher Guide gives a daily flow, teaching language that emphasizes multiplicative reasoning (not adding the same number), common misconceptions, differentiation, and a rubric.
Builds the foundation for proportional reasoning in grade 7.
Why teachers use it
- Three days of lessons with consistent real-world contexts
- Uses tables, double number lines, tape diagrams, and equations
- Directly addresses additive-vs-multiplicative thinking errors
- Unit price comparison for consumer math
- Includes rubric, exit ticket, and full answer key
Questions
Which grade is this?
Grade 6 (CCSS 6.RP.A.1-3), and a useful review for grade 7.
Does it include percent?
No. Percent (6.RP.A.3c) and unit conversion (6.RP.A.3d) are good follow-up lessons.
Can students use calculators?
Optional. The numbers are chosen so the work can be done by hand.
