Each of the "Tricky Words" on a pretend dollar bill. Photocopy the pages on green copy paper and have each student cut out their set of "Money".
Print the page that says Word Wallet, fold in half the "hot dog" way and staple the sides. Now you have a wallet that will hold your money.
One of my first graders pointed out that we have a Word Wall in class with all of the Tricky Words, and the students have Word "Wall"ets. Pretty slick :)
I use these in lots of ways, just like flash cards. For some reason, having them in the form of money just adds to the excitement!
