Students solve problems involving tax, tips and discounts. In this algebra lesson, students convert between percents and decimals. They calculate commission using conversion from percents and fractions.

Second graders rotate through various centers designed to practice consumer math skills. They complete a task card at stations simulating consumer transactions that would take place at toy store, grocery store, restaurant or school store.

Fourth graders use their computation skills and a menu from a local restaurant to plan a lunch with a cost of $5.00 or less.

Students explore the concept of estimating by watching a video, and discussing the strategies for estimation. They estimate the costs for various menu items, then calculate the exact amount spent.
