We play word mat in our dementia facility, we have a old piece of curtain and on the backing its divided up into squares each with 1 letter from the alphabet then we ask a resident to throw a quoits hoop or bean bag on to the mat and then what ever letter it lands on they have to come up with as many words as they can with that letter or sometimes I just give them a letter to use.
