• Lightbulb Students will be representing problems involving ratios and rates. They will use representations of scale factors, tables, graphs and proportions. It is important that when given a problem situation, students can create or determine each of these and use them as a way to “prove” their answers. Also, if given one of these representations, students should be able to create the other three. Getting used to using each of these representations will also help students compare and determine which is the most effective for them, or for the given scenario.
