prefix and suffix spoons game

Play spoons to learn prefixes re-, pre-, and un- as well as suffixes -s/-es and -er. 

You play spoons by having 4 cards each and passing a card to the person on the left all at one (dealer or all say 'switch'). Switch cards every 5 seconds until someone matches all 4 cards in meanings (e.g. unpack, uncomfotrable, not;opposite, and unlock)--that persoon quietly takes a spoon and everyone else should grab a spoon, leaving one person without a spoon. The person without a spoon challenges the first person to explain their answer. If they can explain it, the one with no spoon write S, if they can't, they write S. Continue until someone has all the letters to spell 'spoon'.
