igloo project:
one pre-painted-with-glittery-silver-paint paper plate with a line drawn down the center, two people per plate, scissors for both, cooperative work!
then letter-shape, word-shape writing:
don’t forget to cut a door shape if you want a way in!

Nice. Some of my co-workers made an igloo in their classroom w gallon milk cartons duct-taped together. It took up a huge corner of the classroom, big enough for multiple students to enter and stand up. Lots of milk cartons and duct tape.
