Chapter Summary

Summary

In these concepts we used proportional reasoning when we interpreted map scales, when we determined better buys, and when we used coupons for percent discounts. We thought about equality and inequality when we learned about the distributive property. We saw variables as unknowns when we modeled systems of equations. We also saw variables as varying quantities when we completed tables for functions and applied area and perimeter formulas to solve problems. In all of the concepts, we practiced interpreting representations of mathematical relationships when we looked at circle and arrow grid diagrams, weight scales, discount coupons and maps.
