A page that has 25 squares to cut up, with contraction words on them. There is also a "header" that I use to have them sort their words under. I have the kids sort them everyday and then they play a different game with them. Such as: slap jack, (when the same contraction ending comes up whoever slaps it first gets it) memory, and bingo (they each turn one over and place it under the correct sort in the header). There is also cards that have the two words that make up the contraction as well.
