Story Problems and Subtraction

The second and third grade students have been working so hard on learning how to understand and do two-digit subtraction, with and without regrouping.  When we finally had started to get a handle on it, we decided to make it really fun...we went shopping!!!  Well, pretend shopping with play money, but, boy, was it ever fun!  The boys and girls each went on a website (the boys went on Toys R Us and the girls chose Justice).  I gave them each an envelope of play money with $99 and they got to pick items to buy.  Each time they bought an item, they had to subtract to see how much money they had left and to see if they had enough to buy more.  What a great real life activity!  They finished the project by writing story problems for some of their purchases.
