        Thinkport | Proportional Relationships and Slope: Part 1

        Generate unit rates, ratio tables, and graphs in order to determine which baker wins a cupcake bakeoff in this interactive from MPT. In the accompanying classroom activity, students use the interactive and then solve a similar real-life problem. They share their strategies with the class and then conclude by considering ways that unit rates can facilitate comparing rates. To get the most from the lesson, students should be comfortable graphing points in the first quadrant of the coordinate plane and converting between fractions and decimals. For a longer self-paced student tutorial using this media, see "Unit Rates and Slope" on Thinkport from Maryland Public Television.
