Lesson 4. Unit 2. Grade 6 Open Up Resources
This Instructional Activity is a part of the Lesson 4, Unit 2, Grade 6. In this activity, students mix different numbers of batches of a color recipe to obtain a certain shade of green. They observe how multiple batches of the same recipe produce the same shade of green as a single batch, which suggests that the ratios of blue to yellow for the two situations are equivalent. They also come up with a ratio that is not equivalent to produce a mixture that is a different shade of green.
