Some on asked for more 2's and 3's arts and crafts. In archive II I gave some ideas I have used with young kids using crayons, markers and paint.
Crafts are to create a specific item, like a placemat or vase or some such.
Arts are expressing ideas and exploring the mediums. 2's and 3's are still getting things together with hand eye coordination, and large and small muscle control. The open endedness of arts is more child friendly than the product orientedness of crafts. Paint on a lamp shade instead of paper. Laminate a picture between clear contact paper to make a place mat.
