This lesson builds on students’ work with finding constant of proportionality in tables. In this task, students will determine the amount of data needed to download 100 songs from different internet service providers. By finding the constant of proportionality (MB per song), the students can calculate the how many MB are needed to download 100 songs. The mathematical concepts in this lesson build toward students’ future work with using the constant of proportionality to write equations and finding slope in 8th grade. Students will learn to identify the constant of proportionality in graphs by recognizing that in the point (1,r) r is the constant of proportionality and dividing the y-coordinate by the x-coordinate of a point Big Ideas: All equivalent ratios have the same quotient which is the constant of proportionality. Vocabulary: constant of proportionality, x-coordinate, y-coordinate, Special Materials: calculators
