The Chute  

The chute is a special/fun posting box which is designed for posting cards with something on each side. You post it with one side facing up, and it pops out of the bottom showing the other side. You could use this for phonology work for example, having picture cards with the initial sound written on the back. The pupil says the initial sound for the picture, posts the card and checks if they were right from the card when it comes out the bottom.
