BrainBox First Numbers is designed to give pre-school children a head start.
Each sturdy double-sided card shows different quantities or numerals on one side. The back shows just one of each image, or the image with the numeral missing, with the question, "How many?" or "What number?"

The object of the game is to look at and talk about a card, then turn it over and try to remember how many of each image was shown, or which numerals were on the images. If the numbers are given correctly, the card is kept, and the person with the most number of cards after 5 or 10 minutes is the winner.
