The object of the game is to fill up your game board with cards. They turn the cards over face down and take turns turning them over. If they are able to name the letter/sound/number/etc., they may keep their card. If they can't, it goes back in their pile. If they draw a Vroom, Vroom! card, they may remove a card from the other player's board. I love this game because you can differentiate for each child. You can have one group working on letters/sounds/numbers, while the other group is working on sight words or CVC words. Sight words and CVC words are available in the transportation activity pack in my store.
