Speed!

"Speed!" is a card game designed to teach children to multiply and how to multiply faster. There are eight decks of cards that come in a rainbow of colors. Each deck focuses on skip-counting by a different number (2-9). Once familiar with the numbers in a game, multiplication becomes simple. Two people play against each other to see who can get rid of all their cards first. There is no taking turns and is someone shouts "speed" when the played cards are the same their opponent must add the played cards to his/her stack.
