You’ll start by teaching students how to calculate unit price, followed by teaching them how to calculate discounts. Next, you’ll take them through fixed and variable costs. Then, students will use their new skills to find the better buy on an imaginary family road trip to the beach! They’ll have to find the better buy on car rentals, rest-stop snacks, and accommodations. Finally, they’ll reflect on considerations as they make a decision between individual tickets and a family pass at an amusement park.
