Invest in individual whiteboards this saves on paper. Need a dry erase marker, a black sock (used as an eraser), and a whiteboard. They store these items in a large stretchable book cover (I got mine at Target for about .80 each during the back to school sale) that is placed on the back of their chair.
Nail Aprons for individual desk storage. Amazing idea. Ask HD for a teacher discount... Also, see if paper can fit in them. Might keep students from having to get up all the time. Keep pens, ruler, etc. in the pouch for easy access.
Once baked, salt dough can last for years, making these Easter egg ornaments a wwonderfully cheap way of decorating for Easter. With a bit of clear varnish, they can even be hung outside! Amy Christie explains how to make them. Why not get the kids to help you decorate them, for personal, memory-filled decorations that you can bring out year after year?
