ISBN 0590972847 - This series attempts to make math fun, and for the target audience (ages 6-8 in this case), maybe they'll succeed.
Jeff wants to be the best - at almost anything! His friends are better at baseball, sledding, leaf raking... and he's determined to come up with something he can win. When he decides to make the biggest snowman ever, he and Maria each make one and then measure them to see whose is bigger.
I'm all for anything that even tries to make math more fun for kids, so the 5 stars is more for that than for the content, which is just okay. The illustrations are bright and colorful and the activities pages at the back of the book are full of fun stuff that all relates to using math. Not bad at all - for a book about math!
