This store catalog activity can be used in a number of different ways. The students work together to create story catalogs that will attract customers to their store. The prices used can always be changed depending on the ability level and grade level of your students. This activity can be used to work on adding/subtracting money, estimating a cost based on an amount you have to spend, as well as practicing multiplication. After the students create their catalog they will also create an order form for other students to shop with. This is an easy activity to differentiate learning with.
