In this interactive Proemthean board activity students click on a box of their choice. Each box leads to another page that holds a collection of hidden items from the category. They will pull items from a box. Each box has a price tag on it. The teacher will decide what denomination bills to use to pay. There are Part-Whole models color-coded green and red to use for problem solving.
The items the kids get to purchase are from a SUPER COOL brainiac games site called Mindware. Check it out!
