This lesson extends students’ understanding of ratios to include thinking about the relationship of part to whole in a real-life situation and the percent equivalence. Rather than teaching students a quick algorithm for finding the percent of a number, this approach allows students to visualize the percent as representing an equivalent ratio.SWBAT construct and interpret a double number line model for solving percent problems involving finding the whole or a part of the percent.
