I have laminated my A4 bird photos then either cut them into 1/3rds or 1/4. I demonstate to my Special Needs / Dementia residents how to put the puzzle back together. I then help them have a turn . Gradually they can try themselves. I often find they can be involved in reminiscing or 1:1 chats. Make sure the photos are large enough for the vision impaired residents. While this activity is happening I play my" NZ native bird song" CD, , the nurses are "crazy" for this CD!!
