Here is a very simple idea for an advent calendar which the kids can put together themselves and enjoy during the Advent period.
You will need:
Cork pin board
Wrapped sweets (candy)
Paint the pin board however you like, but make sure you include the numbers 1-24.
Pin 24 sweets to the board, one on each number. Everyday you can take one away!
Pin board advent calendar - empty! It must be Christmas!
