For 10 flower friends, the grass is always greenerin the sky.Ten Fantasia-like flowers with adorable faces and leaf arms/hands love being together and basking in the sun, but they also can't help wanting to break free of their roots and fly when they see the fairies flitting about in the moonlight. One night, "Said the tiny blue one, / Fairy up in the sky, / you see, I'm a flower, / but I want to fly.' " While the fairy is puzzled at the flower's discontent, she grants its wish and transforms it into a butterfly. One by one the others join their mate in the sky as butterflies, each one's color reflecting its flower origin. At daybreak, though, the new butterflies regret the transformation, and the understanding fairy changes them back again: "But big and tall, / or short and small, / being ourselves / is best of all!" Really? There isn't even one flower that would really rather fly all the time? Throughout, McKellar emphasizes that there are always 10 in all, though some may be flowers and some butterflies at any given point. The endpapers reinforce ways to make 10 by showing 11 combinations, all in two rows of five, which may confuse children, rather than always keeping butterflies separate from flowers and allowing one row to be longer than the other. The bright colors, butterflies, flowers, and the fairy, who is a dark-skinned pixie with long black hair, seem calibrated to attract girly audiences.A deterministic message detracts from the math.

Ten flowers ask a local fairy to help them achieve their dreams of flight; the fairy complies, turning them into butterflies. Actor, author, and math advocate McKellar uses the flowers' story to touch on concepts of addition, subtraction, and regrouping: "2 butterflies flew as/ 8 flowers looked on./ There were still 10 of them-/ in the sky, on the lawn." Creating a cast of anthropomorphic flowers isn't easy, and Bricking goes in a glossy, commercial direction in her images, giving the flowers large doe eyes and expressive leaf "limbs." Although McKellar's verse can get herky-jerky or syrupy ("But big and tall,/ or short and small,/ being ourselves/ is best of all"), parents may find this backyard fantasy a useful way to jump-start their children's interest in math.
