There is a buzz in the air in room 302, as students excitedly soak up new knowledge. Whenever possible, I like to ensure that the lessons I teach have a real-life application; that my students will actually use these skills and knowledge in their lives, either now or later. So as we launch into our math unit on Financial Literacy, to support our Food Truck businesses in Who We Are, we begin with quick snapshot of the students' prior knowledge of percent by turning our classroom into a breakfast cafe.
Students are invited to sit in tables of 3-4 and each is given a menu (a real White Spot menu from a few years ago). They're instructed to order breakfast, including beverages, and dessert if desired, and record their order, and the prices, on an individual whiteboard. They then need to calculate their individual portion of the bill, the total bill for the table/group, and how much of a tip to leave based on 15% tipping. Those that find the 15% calculation easy, are challenged to calculate an 18% tip.
Students are then asked to pair/share with a partner other real-life applications of percent. Calculating tax, discounts, BOGO prices, and boxing week sales are some of their responses. No "when are we going to use this?" asked in today's math lesson!
