Zany Chain - Summary: It's like win, lose or draw. They pick a card and read the clue. There are three ideas on the card and they choose one to draw with a metail chain (like a long necklace) on the table.
Playfoam - Oh, my gracious. This is the coolest stuff ever. The students were so excited to work with it. The best I can describe it, is if playdoh and a rice krispie treat had a baby, it would be this stuff. It doesn't stick to the table. If you seal it in a bag it stays good for over a year. It's pricey, but worth the splurge.
Magna Doodle - Available at a yard sale near you
Block Buddies - Like tangrams, but for younger kids. Making picture mosaics to match a picture card
Drawering - This year I had four ipads available as a station. I limited them to this app, no selfies, etc. I think the novelty worked, because they didn't fool around at all. They get very zen and relaxed with this. It's like a spirograph without the little circle, wheels where your pen pops out of the space every 3 minutes.
Rubik's Race - Match the pattern by sliding the tiles. Square Up is another version, which I prefer because they each get a separate board and don't have to be seated across from one another. It allows for solo play and includes two shakers.
Scratch Art Anything - I've had them do trees, mittens, bookmarks. Anything to use up the scraps or colors no one wants.
Many of these items would also be good year round in an art center for early finishers.
