The items you will need for this game are right under your noses! I used things around my house and made the price tags out of notecards. If you don't have notecards, paper would work just the same. Oh, almost forgot, you need money, how can I forget that! So I have play money, again if you don't have play money, you can use real money or you can do a google search for printable play money.
I would love to hear how you practice counting money with your kiddos, let me know in the comments!
