Christmas Subtracting - Learn Math for Kids with Monster Trucks and Lizzy the Dog

'Tis the season...to learn about math. Your kids will love learning about subtracting with the help of Lizzy the Dog and our awesome monster truck. We'll help Santa and his elves "subtract" blocks of ice from the road so they can make enough toys in time for Christmas. We'll also learn about numbers up to twenty as well as the number zero.
