Easy to make and easy to play!  Grab 2–$1 decks of Go-Fish cards from Dollar General.   Use a sharpee to write on them.  We used phonograms, but I could see this done with state abbreviations or periodic chart element abbreviations.  Although the original game had 4 matches to a set, we did ours with 2 so we could get more information in.  Play just like you would Go-Fish but ask for the card by letter sound(s) or name of state etc.  They’ll be begging to play.
