Wet noodle is so fun. Watch this demo! Tape a cup full of water to the top of a pool noodle. I'd tape a "hold here" on the noodle. The kids race to pass it up and down the line without spilling the water.
Giant Connect Four! Use a yellow shower curtain, red and black paper plates, velcro on the back of the plates and in the corresponding spots of the yellow background, and hangs up with tape when residents want to play!
