BrainBox First Letters is designed to give pre-school children a head start. Each sturdy double- sided card shows three images with their initial letters on one side and just the images on the other, with the question, “What letter?”. The object of the game is to look at and talk about a card, then turn it over and try to remember the initial letter of each image. If the letters are named correctly, the card is kept, and the person with the most number of cards after 5 or 10 minutes is the winner.
