Up to My Knees!

Now in Spanish bilingual editions--Caldecott Honor winner Grace Lin celebrates math for every kid in this board book series.

Mei explores measurement as she plants a sunflower seed and watches it grow. The plant starts off as tall as her toe, but soon it's up to her knees, then her waist, then her shoulders. How tall will it get?

The Storytelling Math series shows that all children can be mathematical thinkers. Each book includes ideas for exploring math at home with your children, developed in collaboration with math experts at STEM education nonprofit TERC Inc., under a grant from the Heising-Simons Foundation.Grace Lin is the author and illustrator of more than twenty books for children, including the Newbery Honor Book Where the Mountain Meets the Moon (Little, Brown), the Geisel Honor Book Ling and Ting: Not Exactly the Same! (Little, Brown), and The Ugly Vegetables. She is also the co-author and illustrator of Our Seasons. She lives in Florence, Massachusetts.
