Students began this unit by reviewing what they have already learned about ratios. They knew how to write ratios to represent a given situation, and also knew how to write equivalent ratios. Using their knowledge of ratios, students were able to find unit rates to compare two prices to determine which was a better deal. They applied this understanding of unit rates to play a game of unit rate "go-fish," in which they asked their partners for the unit rates of the rates they had on their cards. Next, students learned different ways to solve proportions, applying the algebra they learned earlier in the year. They looked at how the different methods are similar, and discussed when each method would be best. Finally, students are applying their knowledge of proportions to similar figures. They are using proportions to determine the ratio of corresponding sides of similar shapes and using that ratio to find the value of missing lengths.
