Print these on card stock, laminate and then put them up on a Bulletin board. Have students see how many words they can come up with out of just those letters! The words BOGGLE are also provided in the pdf, so that you can put it as the heading of your bulletin board!
*Note*: I like to print out 2 FULL sets and laminate them, so that more than 1 of the same letters can be up on the board at a time! I use mine on my chalkboard with magnets on the back!
