In our efforts to reform mathematics education, we've learned a tremendous amount about young students' strategies and the ways they construct knowledge, without fully understanding how to support such development over time. The Dutch do. So, funded by the NSF and Exxon, Mathematics in the City was begun, a collaborative inservice project that pooled the best thinking from both countries. In Young Mathematicians at Work, Catherine Fosnot and Maarten Dolk reveal what they learned after several years of intensive study in numerous urban classrooms.
The first in a threevolume set, Young Mathematicians at Work: Constructing Number Sense, Addition, and Subtraction (Grades PreK3), focuses on young children between the ages of four and eight as they construct a deep understanding of number and the operations of addition and subtraction. Rather than offer unrelated activities, Fosnot and Dolk provide a concerted, unified description of development, with a focus on big ideas, progressive strategies, and emerging models. Drawing from the work of the Dutch mathematician Hans Freudenthal, they define mathematics as "mathematizing"—the activity of structuring, modeling, and interpreting one's "lived world" mathematically. And they describe teachers who use rich problematic situations to promote inquiry, problem solving, and construction, and children who raise and pursue their own mathematical ideas.

In Young Mathematicians at Work: Constructing Multiplication and Division (Grades 35), the second book in the threevolume series, Fosnot and Dolk focus on how to develop an understanding of multiplication and division. Their book:
 describes and illustrates what it means to do and learn mathematics
 provides strategies to help teachers turn their classrooms into math workshops that encourage and reflect mathematizing
 examines several ways to engage and support children as they construct important strategies and big ideas related to multiplication
 takes a close look at the strategies and big ideas related to division
 defines modeling and provides examples of how learners construct modelswith a discussion of the importance of context
 discusses what it means to calculate using number sense and whether or not algorithms should still be the goal of computation instruction
 describes how to strengthen performance and portfolio assessment
 emphasizes teachers as learners by encouraging them to see themselves as mathematicians.

In Young Mathematicians at Work: Constructing Fractions, Decimals, and Percents (Grades 58), the third book in the threevolume series, Fosnot and Dolk focus on how children construct their knowledge of fractions, decimals, and percents. Their book:
 describes and illustrates what it means to do and learn mathematics.
 contrasts word problems with true problematic situations which support and enhance investigation and inquiry.
 provides strategies to help teachers turn their classrooms into math workshops.
 explores the cultural and historical development of fractions, decimals, and their equivalents and the ways in which children develop similar ideas and strategies.
 defines and gives examples of modeling, noting the importance of context.
 discusses calculation using number sense and the role of algorithms in computation instruction.
 describes how to strengthen performance and portfolio assessment.
 focuses on teachers as learners by encouraging them to see themselves as mathematicians.

In contrast to other books on math reform the Young Mathematicians at Work series provides a new look at the teaching of computation. It moves beyond the current debate about algorithms to argue for deep number sense and the development of a repertoire of strategies based on landmark numbers and operations.

In their Young Mathematicians at Work series, Catherine Twomey Fosnot and Maarten Dolk described Mathematics in the City, an innovative project where teachers helped young children construct a deep understanding of number and operations in a math workshop environment. Now they and two colleagues from the project have developed a 21stcentury approach that provides pre and inservice teachers with an interactive, videobased, digital context for inquiry into the teaching and learning of mathematics.
Designed for workshop leaders and college instructors, each Resource Package consists of three valuable components:
 A CDROM (developed by Maarten Dolk and Catherine Twomey Fosnot) that offers users a multimedia learning environment for professional development on topics ranging from instruction to assessment, and that stimulates action, reflection, and discussion with dynamic video clips, children's work samples, and interviews with students and teachers
 A Professional Development Overview Manual that provides general advice on teaching in a digital environment
 A Facilitator's Guide (developed by Antonia Cameron, Sherrin B. Hersch, Lynn Tarlow, Suzanne Werner, Bill Jacob, Carol Teig, and Catherine Twomey Fosnot) specific to the CDROM that includes suggestions for using the video clips; sample dialogue from fieldtested sites; facilitation tips; and more. System Requirements for CDROM
Through these resource packages users also are able to study teachers at work: designing rich contexts for problem solving; listening to, questioning, and interpreting students' thinking; drawing connections between mathematical ideas and strategies; and, ultimately, developing a vibrant mathematical community.
Addition and Subtraction Minilessons
In Addition and Subtraction Minilessons, clips of real teachers conducting effective minilessons in real classrooms show you how these short, focused sessions can build big mathematical thinking in young learners.
These video clips support and extend the teaching throughout Contexts for Learning Mathematics' Investigating Number Sense, Addition, and Subtraction (K3).

Taking Inventory: The Role of Context
In Taking Inventory, K1 students inventory materials in their classroom, along the way, developing number sense, counting strategies, and the big ideas underpinning place value. The Resource Package helps teachers examine children's numeric thinking; investigate their strategies; and analyze how they model their classroom mathematically.
These video clips show the teaching and investigations from Investigating Number Sense, Addition, and Subtraction's Organizing and Collecting: The Number System.

Exploring Ages: The Role of Context
In Exploring Ages, Grade 3, students explore addition and subtraction through the lens of ages, building new understandings and strategies and learning concepts like removal, missing addends, and constant difference as they solve problems that reflect their natural curiosity.
These video clips show the teaching and investigations from Investigating Number Sense, Addition, and Subtraction's Ages and Timelines: Subtraction on the Open Number Line.

Working with the Number Line: Mathematical Models
In Working with the Number Line, students construct a number line, initially as a model to represent a measurement situation, and then as a model to represent their computational strategies. Eventually, the students begin to use the model as a tool for thinking. The Resource Package helps teachers examine children's numeric thinking; investigate their strategies; and analyze how they model their world mathematically.
These video clips support and extend the model development throughout Contexts for Learning Mathematics' Investigating Number Sense, Addition, and Subtraction (K3).

Fostering Children's Mathematical Development: The Landscape of Learning
Fostering Children's Mathematical Development focuses on short video clips from interviews, routines, minilessons, games, and investigations. The clips provide opportunities for teachers to observe, analyze, and discuss critical moments in children's development, and then to build a landscape of the ideas, strategies, and models of early number, addition, and subtraction. The Resource Package helps teachers examine children's thinking; investigate their strategies; and analyze how they model their world mathematically.
These video clips support and extend the learning and strategy development throughout Contexts for Learning Mathematics' Investigating Number Sense, Addition, and Subtraction (K3).
