How Many Seeds in a Pumpkin? by Margaret McNamara

How Many Seeds in a Pumpkin? by Margaret McNamara, illustrated by G. Brian Karas, Schwartz and Wade Books, 2007, ISBN 978-0-375-84014-2
PS: Charlie, the smallest child in his first grade class, is amazed to discover that of the three pumpkins his teacher brings to school, the smallest one has the most seeds.
Wait for Fall, grab 3 different-sized pumpkins, and let the math begin! Great for first graders, who are just beginning to count in different ways (by 2's, by 5's, by 10's). The story is entertaining enough, and the suspense (who can wait to see which pumpkin has the most seeds!) will keep students interested while they count away.
You may or may not want to actually clean out the pumpkins and count the seeds, as the teacher does in the book...
But don't let the other lesson slip by: Don't judge by appearances.
Pumpkin facts in the back will add to the learning experience. (Did you know that pumpkin is a fruit, not a vegetable?!)
