Common household items can be used creatively with your child to teach him about his world. Try dry beans, raw rice, and macaroni for pouring instead of water. Include funnels, muffin tins, and measuring spoons and remember metal gives more feedback to your child. Hair curlers with prickles stick to a variety of textures along with hair. Many young children need encouragement to feel different textures.
Some textures are less offensive if put inside a zip-lock bag.
Try hiding their favorite food, such as raisins or grapes in Cool Whip or cereal. Clothespins are great for developing fine motor skills. They build finger strength for brailler use and writing activities. Make up a game with them by pinning them on clothes, paper, etc. and having your child take them off and put them in a bucket. It is a harder skill to pin them back on to an object, but some children will learn to do so.
