Grace Lin adds to her math concept series with four new board books featuring three diverse preschoolers. In Who Jumps More?, about measurement, Olivia (Black) and Mei (Asian) take turns jumping in the snow like a rabbit (Olivia) and a reindeer (Mei), each covering the same distance in hops of different sizes. Where Are the Eggs?A Beautiful House for Birds, using different colors of paint to create a pattern that goes from simple to more complex. And in Our Favorite Apples, Manny (Latine) goes apple-picking with Olivia and Mei, and the three decide to sort their harvest by color. The brief volumes conclude with more about the skills that the featured concept in each book develops, and suggested “Try This” activities. (Ages 3–5)

Caldecott Honor winner Grace Lin celebrates math for every kid, everywhere!

Olivia and Mei jump in the snow all the way to the tall tree. Mei takes a few big leaps like a deer. Olivia makes lots of smaller hops like a bunny. Each jumps “more” in a different way. A playful exploration of measurement, proportion, and friendship.

Storytelling Math celebrates children using math in their daily adventures as they play, build, and discover the world around them. Joyful stories and hands-on activities make it easy for kids and their grown-ups to explore everyday math together.
