This sequence of three lessons explores ratios through the context of mixing paint. Students investigate how ratios express a multiplicative relationship between two measures and under what conditions the proportions remain constant when the numerical values of both quantities change. The lessons are outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points, suggested strategies and student resources. This sequence is part of the reSolve: Maths by Inquiry program.
