Use a Cracker Barrel Menu to allow students to order, calculate tax and tip, as well as join a group to determine the groups total bill. The Cracker Barrel in my area gave me real menus to use for this project free of charge. If you don't have a restaurant in your area, the menu can be accessed online. This performance task allows students to practice adding, subtracting, and multiplying decimals in a real world setting. Every year, this is my students' favorite activity!
