Create a real life math activity by having kids work out decimal math and percents problems in a "virtual restaurant" in your classroom. Print out or obtain to-go menus from a restaurant. Then, arrange your classroom like tables in a restaurant. (I actually acted like a maitre d' and "sat" students as they entered.) Provide students the task directions on one side, and the sales ticket and credit card slip on the back (in this file). Students determine the cost of their bill and the tip. Can repeat with different orders or restaurants.
