This WebQuest is designed to give students the opportunity to apply their addition, subtraction, multiplication, and division skills in an authentic learning situation. I would suggest that students have experience adding and subtracting money, and a basic understanding of how to multiply by a percentage (though the directions do show examples).
I created this WebQuests with 4th graders in mind, but I believe that it can be easily modified to work for students Grades 3-6. In this WebQuest, students will work in groups of five to use a menu to order food, record their choices and add up the cost, multiply to find the tax and tip, divide the cost among the members of the group, and subtract to determine the correct change. I would allow for two class periods to complete this WebQuest, or it could be used as a center in math rotations. The timing and teacher involvement may need to be altered to better suit various grade levels.
