Objectives: To allow students a true to life experience with math.
Pre-assessment would involve a discussion about when you use percentages in “real” life and would involve a small quiz to check how much the students know.
Sample quiz questions: How much is 15% of 100? How much is 15% of 50? How did you get this figure?
Procedures:
1 MIN Introduce activity, divide students into wait-staff and customers. Allow customers to randomly pick coupons.
6 MIN Customers spend this time deciding on what to order and how to pay. They will be working in pairs so they will have to decide which coupons with be the most cost saving for their order. Their Essential Question: Should we pay separate or together?
During this time the wait-staff should be getting familiar with the calculators and discussing how to figure up sale tax. They too, will be working in pairs.
6 MIN Wait-staff will take the order and tally the prices, figuring in coupons and tax.
2 MIN Customers will double-check the ticket and figure for appropriate 15% tip.
2 MIN Wait-staff will double-check whether tip is adequate.
If in a regular classroom, there would be a “show and tell” from the customers as to how they figured out the best deal for their coupons showing the class their methods. Also wait-staff would have to show how they figure the sales tax and the coupon deductions.
Post assessment would be a written “showing of their work” after the discussion, explaining any new ways of doing percentages they may have learned.
