hair gel + food coloring = great OT/sensory play (add in color and letter/sound recognition and spelling for older kids who still need the OT) Used this for my preschool class.they loved it.just make sure you tape them shut or they will pop them :)
Play Create Explore: Baby Oil Sensory Bags = baby oil, food colouring, a little bit of water, glitter, objects to find (smooth). Put in ziplock bag and duct tape for leaks and little fingers who would like to open it. ((or a heat seal bag))
DIY Sand and Rock Box by FSPDT. Gdjk -> made this with toilet rolls (aka tunnels) and moon sand instead of play sand. My son loved playing with it. The moon sand cleans up nicely indoors but play sand will be easier to play with when using the small cars.
Easy and fun.Velcro + popsicle sticks make for great quiet time or restaurant activity. Put velcro dots on the ends of popsicle sticks. Kids can make letters or shapes over and over again. I found velcro dots at my local dollar store.
Popsicle Stick Puzzles - An easy storage idea is a plastic baggy. These puzzles would be great to put in a diaper bag or purse to pull-out when you’re on-the-go and need a quiet activity! Could also add the little magnets to the back for fridge fun.
