Hi you could try play dough they like to roll it and just pull it apart you can get plastic cookie shapes. Blocks like Lego. Giant snakes and ladders they can roll the dice you would have to do the moving around. Musical instruments they can shake or tap on. Picture puzzles they can feel and put into certain holes. Colouring in just basic stencils. Singing old songs. Hope this helps. I've done the opposite gone from disability day centre to a high care nursing home.
One of the best sites I have ever come across that supports clients in a person-centred and meaningful way. The resources are so user-friendly and there is always something new to learn. Thank you!
