Who Has More? is a wonderful resource for parents, caregivers, and educators who want to start introducing their kids to mathematical ways of thinking.

Lani and Rabbert were so thirsty after playing outside one hot summer afternoon. They ran into the house to get the biggest drink they could find. But which cup holds more? With vivid illustrations, young readers can follow Lani and Rabbert as they observe, explore, and experiment and, along the way, become aware of the everyday math around them.

This book was inspired by the Measure Up math curriculum project, a project of the Curriculum Research & Development Group (CRDG) at the University of Hawaiʻi at Mānoa. Measure Up promotes an innovative approach to early grades mathematics that uses familiar quantities that children encounter in their everyday lives. We hope this book serves as an inspiration for you and your child to broaden your view of math.
