These extra large dice are loads of fun indoors or out. Play any dice game with them, use them to choose chores, buy a pair to teach addition. The possibilities are endless. A favorite around our yard is the giant step game, where each child rolls their own dice and takes that number of steps, trying to get from one side of the yard to the other. These dice are make of unfinished wood with woodburned markings. Never treated with chemicals or toxins, they measure 3.5" square. The price is for a single die, so you can buy just the amount you need. Order up some fun for your family!
