Students are asked to decide which would be the best deal and the worst deal on candy. They can also create their own mixed bags. This activity has unit pricing, philosophy of candy collecting, and Excel if you would like to use technology.
Consider starting out the activity three act style: Show kids the pictures, ask them what questions they have. Settle on “Which bag is the best deal?” Have them make a prediction. Provide them with the activity sheet that has the costs and quantities. Have them work, maybe five minutes of independent think time, so they can generate their own ideas, then five or ten minutes in small groups. Students can find the best deals either using unit rate cost, number of candies for a dollar, or by scaling up to equivalent dollar amounts (ratio table).
