Significant Changes Due to the CCSSM introduction of ratio and rates in 6 th grade, the content of this unit has been combined into three investigation rather than 4. The internal motivation for change was a desire to more strongly connect to, and to more completely develop, the ideas and strategies initiated in CMP3 Stretching and Shrinking. In similar figures, internal ratios, such as length: width, and external ratios, such as side length X: corresponding side length Y, are constant. When students find a missing length in Stretching and Shrinking , they are solving a proportion; they may use a scale factor rather than set up a proportion, but the proportional reasoning is the same. By the end of CMP3 Stretching and Shrinking students will have a method of scaling a ratio up or down to find a missing quantity or by using equivalent ratios, which is an important strategy for solving any proportion. Learning to choose the scale factor efficiently, in similarity and other situations, is a refinement of this strategy.

The philosophy of the counseling program in the School District of the Chathams is that school counseling is an essential, integral part of the educational process. As student advocates, counselors recognize the uniqueness, dignity and personal worth of each individual.
They will see that rate tables are a variation on a scaling strategy, and that unit rates are particularly useful. A relationship in which you multiply one variable by a constant number to find the value of another variable. Investigation 2 has three problems with a focus on rates and the constant of proportionality. Balanced Literacy saling, Geometry.
