Introduction: You have just won a $100 gift certificate to buy some toys! You must try to spend as much of it as you can without going over. Let's go shopping and have some fun!
Prior Knowledge: The learners should know how to add and subtract money with regrouping.
Grade Level: 2-4
Task: The learners will make a display consisting of drawings of some of the toys they chose, a few sentences explaining why they chose those toys, answers to the teacher-made questions, and complete their order form.

Process:
Learning Advice: This is best suited for a computer lab situation and as an individual activity.
Evaluation: Displays should be attractive and should show accurate calculations. Communication should be clear.
Extensions: This could be done in conjunction with Christmas. Students could conduct a survey of the most popular toys and graph the results.
Conclusion: The children will have learned how to fill out an order form and how to shop on a budget. They will also have reinforced their addition and subtraction skills as well as their communication skills.
