Illuminations: Shopping Mall Math

# Shopping Mall Math

Students participate in activities in which they develop number sense in and around the shopping mall. The first lesson in this unit is appropriate for grades 3 - 5, and the second lesson is appropriate for grades 6 - 8. Both grade-level activities deal with size and space, estimation, measurement, and applications involving percent.  This unit was adapted from an article entitled "Mathematics at the Mall," written by Francis Fennell, which appeared in Teaching Children Mathematics, January, 1998, vol.4, no.5,  pp. 268 - 274.
