Deborah Arron Leslie
Debbie Leslie is a senior curriculum developer, early childhood specialist, and Director of Science Companion Projects at the University of Chicago's Center for Elementary Mathematics and Science Education (CEMSE). She provides professional development, coaching, and consultation to support the implementation of Everyday Mathematics and inquirybased science curricula in the University of Chicago charter schools, the Chicago Public Schools, and elsewhere.
Ms. Leslie is also the Early Childhood Team Leader for the elementary component of UCSMP. In this capacity, she led the author team that developed the new version of PreKindergarten Everyday Mathematics and the team that worked on the 3rd edition revisions for Kindergarten Everyday Mathematics. Leslie is also one of the authors of Science Companion, an inquirybased elementary school science curriculum.
At CEMSE, Leslie works on several projects that draw on her background in science and her interest in highquality professional development in the areas of math, science, and early childhood education. Leslie taught PreKindergarten, Kindergarten, and First Grade for 10 years in Connecticut and in the Chicago area. She has also done work for the Bush Center for Child Development and Social Policy at Yale University, the Field Museum, and the Rochelle Lee Fund in Chicago, Illinois, and has done presentations, consulting, and professional development for several other educational organizations. She holds a Bachelor's Degree in Molecular Biochemistry and Biophysics from Yale University and a Master's Degree in Teaching from the University of Chicago.

Jean Bell
Jean Bell is one of the founding authors of Everyday Mathematics and part of the Author panel that has responsibility for general oversight of the Publishing Agreement for Everyday Mathematics and the Center Agreement that established the Center for Mathematics and Science Education (CEMSE) at the University of Chicago.
Early in her career Jean Bell was a microbiologist in the California State Public Health Laboratories and in the laboratory of Dr. Marc Beem at the University of Chicago. In a career change after some years of fulltime parenting Bell began teaching preschool children and then with an MST degree from the University of Chicago became a primary school teacher.
In the early 1980's Bell did interviewbased research on the mathematics capabilities of young children that showed very clearly that these capabilities had been seriously underestimated. This led her to work with other founding authors within the University of Chicago School Mathematics Project (UCSMP) on development of the grades K6 Everyday Mathematics curriculum.
On completion of the First Edition of Everyday Mathematics she returned to her science roots, founding with others the Chicago Science Group to develop the K5 Science Companion curriculum. That curriculum, distributed by Pearson Scott Foresman, seeks to be inquiry based, relatively easy to implement, firmly rooted in "reform" oriented national standards, and easily integrated with such programs as Everyday Mathematics.

Max Bell
Max Bell is Professor Emeritus, Department of Education and the Physical Sciences Division at the University of Chicago and is affiliated with the University of Chicago Center for Mathematics and Science Education (CEMSE). He is one of the founding authors of Everyday Mathematics, and part of the Author panel that has responsibility for general oversight of the Publishing Agreement for Everyday Mathematics and of the Center Agreement that established CEMSE.
Bell shifted in 1960 from teaching high school students to teaching teachers in the thennew MAT program at the University of Chicago. (He had earlier been in an influential NSF funded Academic Year Institute for mathematics teachers conducted by the UC mathematics department.) He spent a decade as MAT Mathematics Coordinator while also working with UC people, SMSG, and other organizations on reformoriented secondary school mathematics materials. But as it became very clear that many children (and nearly all Chicago inner city children) entered secondary school with little understanding of mathematics, Bell shifted his attention to elementary school mathematics instruction and teacher preparation.
Bell's widely reprinted 1973 article ("What does 'everyman' really need from school mathematics?") set an ambitious content agenda that anticipated the 1989 NCTM "Standards." Structured interviews of several hundred five to nine year old children clearly showed that their mathematics learning capabilities were much greater than had been supposed. At the same time, textbook analyses and interviews with teachers revealed an essentially vacuous primary school mathematics curriculum. With those foundations established by 1985, Bell joined with others in the University of Chicago School Mathematics Project (UCSMP) in research, development, field testing, and widespread dissemination of the Everyday Mathematics curriculum for grades K6.
Bell continues his interest in improvement of elementary school science and mathematics teaching, now focused on maximizing the potential for "educative curricula" (from which teachers learn as they teach) to attack well known problems of scale in helping inservice teachers better understand and teach science and mathematics. Also, Bell and CEMSE colleagues are just beginning conceptualization and specifications for a coherent "web based curriculum" for any individual who for any reason wishes to learn mathematics, from basic counting and arithmetic through data analysis, algebra, or geometry.

Diana Barrie
Diana Barrie received her BFA and MFA from the Art Institute of Chicago. She taught photography and filmmaking at the University of Northern Iowa and the University of Wisconsin at Milwaukee.
After working in the reprographics industry in New York City and Chicago, she came to UCSMP in 1990, where she has performed various duties, including creating technical illustrations for all grade levels of Everyday Mathematics. She has also created illustrations for Science Companion and the Center for Urban School Improvement's STEP Literacy Assessments.

Jim Flanders
Jim Flanders is a researcher at the Center for Elementary Mathematics and Science Education (CEMSE) at the University of Chicago where his focus is on integrating technology into the mathematics curriculum. He is a contributing author of several University of Chicago School Mathematics Project (UCSMP) books including Everyday Mathematics, Transition Mathematics, Algebra, Advanced Algebra, and Functions, Statistics and Trigonometry.
Prior to joining CEMSE he was a member of the Chicago Science Group helping develop the field testing of the Science Companion and evaluating software for elementary school mathematics. He also wrote calculator software for the CorePlus Mathematics Project, and was a consultant to the Everyday Learning Corporation and the Louisiana Systemic Initiative Project.

Max Bell
Max Bell is Professor Emeritus, Department of Education and the Physical Sciences Division at the University of Chicago and is affiliated with the University of Chicago Center for Mathematics and Science Education (CEMSE). He is one of the founding authors of Everyday Mathematics (EM), and part of the Author panel that has responsibility for general oversight of the Publishing Agreement for Everyday Mathematics and of the Center Agreement that established CEMSE.
Bell shifted in 1960 from teaching high school students to teaching teachers in the thennew MAT program at the University of Chicago. (He had earlier been in an influential NSF funded Academic Year Institute for mathematics teachers conducted by the UC mathematics department.) He spent a decade as MAT Mathematics Coordinator while also working with UC people, SMSG, and other organizations on reformoriented secondary school mathematics materials. But as it became very clear that many children (and nearly all Chicago inner city children) entered secondary school with little understanding of mathematics, Bell shifted his attention to elementary school mathematics instruction and teacher preparation.
Bell's widely reprinted 1973 article ("What does 'everyman' really need from school mathematics?") set an ambitious content agenda that anticipated the 1989 NCTM "Standards." Structured interviews of several hundred five to nine year old children clearly showed that their mathematics learning capabilities were much greater than had been supposed. At the same time, textbook analyses and interviews with teachers revealed an essentially vacuous primary school mathematics curriculum. With those foundations established by 1985, Bell joined with others in the University of Chicago School Mathematics Project (UCSMP) in research, development, field testing, and widespread dissemination of the Everyday Mathematics curriculum for grades K6.
Bell continues his interest in improvement of elementary school science and mathematics teaching, now focused on maximizing the potential for "educative curricula" (from which teachers learn as they teach) to attack well known problems of scale in helping inservice teachers better understand and teach science and mathematics. Also, Bell and CEMSE colleagues are just beginning conceptualization and specifications for a coherent "web based curriculum" for any individual who for any reason wishes to learn mathematics, from basic counting and arithmetic through data analysis, algebra, or geometry.

Jean Bell
Jean Bell is one of the founding authors of Everyday Mathematics and part of the Author panel that has responsibility for general oversight of the Publishing Agreement for Everyday Mathematics and the Center Agreement that established the Center for Mathematics and Science Education (CEMSE) at the University of Chicago.
Early in her career Jean Bell was a microbiologist in the California State Public Health Laboratories and in the laboratory of Dr. Marc Beem at the University of Chicago. In a career change after some years of fulltime parenting Bell began teaching preschool children and then with an MST degree from the University of Chicago became a primary school teacher.
In the early 1980's Bell did interviewbased research on the mathematics capabilities of young children that showed very clearly that these capabilities had been seriously underestimated. This led her to work with other founding authors within the University of Chicago School Mathematics Project (UCSMP) on development of the grades K6 Everyday Mathematics curriculum.
On completion of the First Edition of Everyday Mathematics she returned to her science roots, founding with others the Chicago Science Group to develop the K5 Science Companion curriculum. That curriculum, distributed by Pearson Scott Foresman, seeks to be inquiry based, relatively easy to implement, firmly rooted in "reform" oriented national standards, and easily integrated with such programs as Everyday Mathematics.

Max Bell
Max Bell is Professor Emeritus, Department of Education and the Physical Sciences Division at the University of Chicago and is affiliated with the University of Chicago Center for Mathematics and Science Education (CEMSE). He is one of the founding authors of Everyday Mathematics (EM), and part of the Author panel that has responsibility for general oversight of the Publishing Agreement for Everyday Mathematics and of the Center Agreement that established CEMSE.
Bell shifted in 1960 from teaching high school students to teaching teachers in the thennew MAT program at the University of Chicago. (He had earlier been in an influential NSF funded Academic Year Institute for mathematics teachers conducted by the UC mathematics department.) He spent a decade as MAT Mathematics Coordinator while also working with UC people, SMSG, and other organizations on reformoriented secondary school mathematics materials. But as it became very clear that many children (and nearly all Chicago inner city children) entered secondary school with little understanding of mathematics, Bell shifted his attention to elementary school mathematics instruction and teacher preparation.
Bell's widely reprinted 1973 article ("What does 'everyman' really need from school mathematics?") set an ambitious content agenda that anticipated the 1989 NCTM "Standards." Structured interviews of several hundred five to nine year old children clearly showed that their mathematics learning capabilities were much greater than had been supposed. At the same time, textbook analyses and interviews with teachers revealed an essentially vacuous primary school mathematics curriculum. With those foundations established by 1985, Bell joined with others in the University of Chicago School Mathematics Project (UCSMP) in research, development, field testing, and widespread dissemination of the Everyday Mathematics curriculum for grades K6.
Bell continues his interest in improvement of elementary school science and mathematics teaching, now focused on maximizing the potential for "educative curricula" (from which teachers learn as they teach) to attack well known problems of scale in helping inservice teachers better understand and teach science and mathematics. Also, Bell and CEMSE colleagues are just beginning conceptualization and specifications for a coherent "web based curriculum" for any individual who for any reason wishes to learn mathematics, from basic counting and arithmetic through data analysis, algebra, or geometry.

Max Bell
Max Bell is Professor Emeritus, Department of Education and the Physical Sciences Division at the University of Chicago and is affiliated with the University of Chicago Center for Mathematics and Science Education (CEMSE). He is one of the founding authors of Everyday Mathematics (EM), and part of the Author panel that has responsibility for general oversight of the Publishing Agreement for Everyday Mathematics and of the Center Agreement that established CEMSE.
Bell shifted in 1960 from teaching high school students to teaching teachers in the thennew MAT program at the University of Chicago. (He had earlier been in an influential NSF funded Academic Year Institute for mathematics teachers conducted by the UC mathematics department.) He spent a decade as MAT Mathematics Coordinator while also working with UC people, SMSG, and other organizations on reformoriented secondary school mathematics materials. But as it became very clear that many children (and nearly all Chicago inner city children) entered secondary school with little understanding of mathematics, Bell shifted his attention to elementary school mathematics instruction and teacher preparation.
Bell's widely reprinted 1973 article ("What does 'everyman' really need from school mathematics?") set an ambitious content agenda that anticipated the 1989 NCTM "Standards." Structured interviews of several hundred five to nine year old children clearly showed that their mathematics learning capabilities were much greater than had been supposed. At the same time, textbook analyses and interviews with teachers revealed an essentially vacuous primary school mathematics curriculum. With those foundations established by 1985, Bell joined with others in the University of Chicago School Mathematics Project (UCSMP) in research, development, field testing, and widespread dissemination of the Everyday Mathematics curriculum for grades K6.
Bell continues his interest in improvement of elementary school science and mathematics teaching, now focused on maximizing the potential for "educative curricula" (from which teachers learn as they teach) to attack well known problems of scale in helping inservice teachers better understand and teach science and mathematics. Also, Bell and CEMSE colleagues are just beginning conceptualization and specifications for a coherent "web based curriculum" for any individual who for any reason wishes to learn mathematics, from basic counting and arithmetic through data analysis, algebra, or geometry.
