A sensory bin is a simple toddler play activity: take a plastic tub, fill it with rice (or another filler), add scoops and containers to pour into (or other tools) and a few of your child’s small toys, and let your child play. The benefits for your child are: learning to use tools, using fine motor skills, and sensory exploration. The benefits for you are that your child will play independently for quite some time while you get other things done! (Expect some clean-up time when you’re done!)
