Hasta Las Rodillas / 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, a New York Times best-selling author/illustrator, won the Caldecott Honor for A Big Mooncake for Little Star, the Newbery Honor for Where the Mountain Meets the Moon, and the Theodor Geisel Honor for Ling and Ting: Not Exactly the Same. Her middle grade novel, When the Sea Turned to Silver, was a National Book Award finalist. Grace is a commentator for New England Public Radio, a reviewer for the New York Times, and a video essayist for PBS NewsHour. You can hear her speak about diversity and children's literature in her popular TEDx talk "The Windows and Mirrors of Your Child's Bookshelf."
