Dice spelling games. Could use for sight words too. Put small numbers that match the dice pips, next to sight words on the wall. Use two di for larger numbers.

Milk jug igloo! I made one of these before, and it lasted months in a room of preschoolers. We decorated it for different themes (cave, beach hut, etc.). My advice would be to be ready with a lot of hot glue, to make sure jugs are washed out well and totally dry, and to glue on the tops (children will love to stuff toys, tissues, and who knows what else into them otherwise!)
