The focus of school mathematics is shifting from a dualistic mission—minimal mathematics for the majority, advanced mathematics for a few—to a singular focus on a common core . . . For all students.

NCTM Principles and Standards for School Mathematics
“All students must have access to the highest quality mathematics instructional programs. A society in which only a few have the mathematical knowledge needed to fill crucial economic, political, and scientific roles is not consistent with the values of a just democratic system or its economic needs.” (p. 5)
“Expectations must be raised.” (p. 13)

NCTM Principles and Standards for School Mathematics
“All students are expected to study mathematics each of the four years that they are enrolled in high school, whether they plan to pursue the further study of mathematics, to enter the workforce, or to pursue other postsecondary education.” (p. 288)
“Whatever the approach taken, all students learn the same core material while some, if they wish, can study additional mathematics consistent with their interests and career directions.” (p. 289)

Principles for School Mathematics
The six principles for school mathematics address overarching themes:
• Equity. Excellence in mathematics education requires equity—high expectations and strong support for all students.
• Curriculum. A curriculum is more than a collection of activities: it must be coherent, focused on important mathematics, and well articulated across the grades.
• Teaching. Effective mathematics teaching requires understanding what students know and need to learn and then challenging and supporting them to learn it well.
6
• Learning. Students must learn mathematics with understanding, actively building new knowledge from experience and prior knowledge.
• Assessment. Assessment should support the learning of important mathematics and furnish useful information to both teachers and students.
• Technology. Technology is essential in teaching and learning mathematics; it influences the mathematics that is taught and enhances students’ learning.

Design Principles
Three years of mathematical study revolving around a core curriculum should be required of all secondary school students. This curriculum should be differentiated by depth and breadth of treatment of common topics and by the nature of applications. All students should study a fourth-year of appropriate mathematics (NCTM, 1989).
Each part of the curriculum should be justified on its own merits (MSEB, 1990).
Mathematics is a vibrant and broadly useful subject to be explored and understood as an active science of patterns (Steen, 1990).
9
Design Principles
Computers and calculators have changed not only what mathematics is important, but also how mathematics should be taught (Zorn, 1987; Hembree & Dessart, 1992; Dunham & Dick, 1994).
Problems provide a rich context for developing student understanding of mathematics (Schoenfeld, 1988; Schoenfeld, 1992; Heibert, Carpenter, Fennema, Fuson, Human, Murray, Olivier & Wearne, 1996).
Deep understanding of mathematical ideas includes connections among related concepts and procedures, both within mathematics and to the real world (Skemp, 1987).
10
Design Principles
Social interaction (Cobb, 1995) and communication (Silver, 1996) play vital roles in the construction of mathematical ideas.
Classroom cultures of sense-making shape students understanding of the nature of mathematics as well as the ways in which they can use the mathematics they have learned (Resnick, 1987; Resnick, 1988; Lave, Smith, & Butler, 1988).

The Most Important Aspects of Teaching Core-Plus Mathematics
as Reported by Teachers
• Creating an atmosphere for risk-taking
• Listening to students
• Planning
• Being able to back off and let the students take responsibility for their learning
• Checking that students are making valid generalizations
• Seeing the big picture
• Closure
• Teachers must understand the content and the extent that mathematics is taught developmentally through cooperative groups and connectively through the strands.
36
Classroom Observations
• Atmosphere of cooperation—students are dividing responsibilities, mediating solutions, and explaining ideas to each other.
• Teachers are circulating among groups listening to, and guiding, student thinking.
• Students are active participants, willing to put forth considerable effort.
• Various approaches to solving problems are encouraged and accepted.
• Students look for patterns and ways to describe them clearly rather than just looking for procedures.
• Teachers believe that ALL students can learn mathematics because they have witnessed and experienced it.
37
• Learning is encouraged through students exchanging ideas, conjecturing, and explaining their reasoning.
• Peer questioning/challenging of thinking and reasoning becomes common place.
• Student confidence in thinking, reasoning, and problem-solving ability improves with time and experience.
• Quality of student written work is impressive.
• A variety of assessment tools, including interviews and observation, is used.
• When using Core-Plus Mathematics with heterogeneously grouped classes, teachers have indicated that they are unable, in many instances, to identify students who traditionally would have been assigned to a lower level class.
