Objective
Students will estimate the size of one ounce. Students will use computation and
problem solving strategies to determine the unit cost of given items.
Overview of the Lesson
“How much is an ounce of cereal?” This is the question students explore as they
pass around small bags of cereal and try to discern which one weighs one ounce.
Students then use computation skills, problem solving and number sense to find
the cost of an ounce of cereal. Students compare the cost per ounce of a variety of
cereals and then speculate as to the reasons for the different prices. Students then
utilize similar strategies in determining the price per chip for bags of snacks and
make comparisons.
