Put paper into a shredder if you have one. Otherwise, cut paper into long thin pieces. You can use a variety of paper. For instance, construction paper, printer paper, magazine sheets, scrap paper, or newspaper. Then put it all in a tub where he can play away. He will be transfixed with pulling the paper apart and feeling how it crumples together.
This is a simple activity that captivates little ones. It usually is the simple ones. Grab a tub and fill it with water. Grab different types and sizes of paper and stack it next to the tub. Example paper types: printer paper, scratch paper, notes, magazine pages, or construction paper. Watch as she dips, pushes, and soaks the paper in the water. After awhile of play, you can add a new element by giving her child friendly tongs, spoons, ladels, or cups to poke, scoop and play with the paper.
Go to the store and pick out different color and shaped pasta. There are spiral, shells, macaroni, or wheels to name a few kinds. Next, dump a bit of each kind in a baking dish or tub and let her explore all the different shapes! Watch so she does not put the pasta in her mouth.
