This is a guided note template for teaching percent discount. This includes a "Do Now" or beginning of class activity (on proportions), an introduction where students make a prediction about which coupon is better $20 off or 20% off, and then notes teaching students how to create a proportion to calculate percent. Students are lead through a series of real life examples (product pictures and prices are featured) and asked to discern which coupon is better. Students end the lesson by practicing independently or with a partner, and then are asked to make a conclusion about when to use a 20% off coupon vs a $20 coupon. An exit ticket is included, along with challenge problems from the ACT, NY Regents exams, and Phillips Exetur Academy.
