Kathy Richardson is known for her deep understanding of how children develop mathematical understanding. This continuum has been described in her assessment program, Assessing Math Concepts, and her curriculum, Developing Number Concepts. Now Richardson and co-author Sue Dolphin have developed a resource for incorporating number talks that supports these core ideas about the development of number concepts into your daily routine. Divided into Instructional Ranges (beginning with Recognizing Small Groups and extending to Addition and Subtraction of Two-Digit Numbers), each range includes 18–20 number talk activities to share with students. Teachers will learn how to use models, questions, and experiences to support children's mathematical development. These 5–15 minute daily routines are a powerful tool to help students develop computational fluency.

Number Talks in the Pre-Kindergarten Classroom

This book is a collection of 15 open-ended mathematics questions for kindergarten, first- and second-grade children. The questions deal with animals, birthdays, mittens, and other topics that capture the interest of young children. The problems are open ended because they have multiple solutions and/or multiple approaches to reach one solution. Children's literature serves as a springboard for many of the lessons. Each lesson contains an overview, materials list, description, student responses and assessment discussion, and references.

Posing Open Ended Questions in the Primary Math Classroom

A must-have book for everyone wanting to know how young children develop and understanding of number concepts. Kathy Richardson has identified the predictable stages, or Critical Learning Phases, children go through as they develop the mathematical understanding that is essential to building a solid foundation of numerical reasoning. This important resource will help all math educators and parents of young children understand how children make sense of numbers and what mathematics they are ready to learn at each phase of development.
