A Valentine Dice Game
Here is a great "candy-free" valentine that Lyndsey has created over at Mamma's Tots.
Each Valentine has 50 circles on the main heart. Children roll the die and fill in the circles. When all of the circles are filled, the child wins! The die is attached to the Valentine with tape, and what could be more fun to play with than a die!
