Diapers

Most of your students probably think a car or college is the first big expense their parents could help them with, but as it turns out these kids have been costing their parents for their whole lives. Have they ever considered how much diapers cost on average? The activities of building tables, creating algebraic equations, and analyzing graphs, is followed with a number of questions that require kids to interpret their results and write about their findings for the algebraic equations they create. An answer sheet is available for a nominal fee on the website (See the additional materials.)
