In the fall of 2024, Citizen Math released updated versions of every lesson in our library, plus a few new ones! We know you may have already prepped an earlier version or planned a repeat of last year, so we're continuing to make these earlier versions available through Thursday December 5, 2024.
You can find the new lessons through the regular search, and we hope you love them as much as we do. You can read more about these updates in Our Community.

Are coupons always a good deal? Retailers like JCPenney use coupons to offer their shoppers great-looking deals, but there’s a catch: Before putting an item on sale, a store often first raises its price.
In this lesson, students reason with percents and proportions to evaluate enticing coupons and debate whether retailers should be allowed to raise the price of items in order to then put them on sale.
