Give examples of ratios as multiplicative comparisons of two quantities describing the same attribute.
The Texas Essential Knowledge and Skills (TEKS) for Mathematics outcome 6.4(C) (Proportionality) for Grade 6 says: “Give examples of ratios as multiplicative comparisons of two quantities describing the same attribute.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Texas Essential Knowledge and Skills (TEKS) for Mathematics.
Mix It, Pace It: Ratio, Rate and Percent Grades 6–7
Why doesn't the big batch of paint match? Who walks fastest? Is the bigger pack or the bigger percent off really the better deal? Does twice the time mean twice the distance? Four lessons where students mix, walk, shop and graph their way to ratios, unit rates, percents and proportional relationships.
- Why doesn't the big batch match? 50–60 min
Teams mix a green paint from 2 spoons of blue and 3 of yellow, then try to make a bigger batch that matches. Adding 2 more spoons of each gives a different green; doubling both gives a perfect match. Students explain ratios, equivalent ratios and ratio tables, and part-to-part and part-to-whole ratios.
