This paper examines mathematics curriculum standards for middle school students, focusing on the National Council of Teachers of Mathematics (NCTM) guidelines for grades six through eight and the K–12 Common Core State Standards (CCSS). It summarizes each of the ten NCTM standard areas—including numbers and operations, algebra, geometry, measurement, data analysis, problem solving, reasoning and proof, communication, connections, and representation—and describes what students in the middle grades are expected to know and be able to do. The paper also reviews research evidence supporting standards-based instruction and highlights findings from studies demonstrating that coherent, teacher-implemented standards-based curricula improve student achievement in mathematics.
In a preface to a discussion about curriculum and standards for middle school, the National Council of Teachers of Mathematics (NCTM, n.d.) notes that "the middle grades represent a significant turning point in students' lives," during which they "solidify conceptions about themselves as learners of mathematics." Students arrive at conclusions about their competence in mathematics, their attitudes, their interest, and their motivation. These conceptions will influence how they approach the study of mathematics in later years, which in turn will affect their later career and personal opportunities.
The NCTM standards guide curriculum development in ten areas: numbers and operations, algebra, geometry, measurement, data analysis and probability, problem solving, reasoning and proof, communications, connections, and representation. For each area, the standards specify what students are expected to know.
Likewise, the K–12 Common Core State Standards (CCSS) are designed to provide a framework on which curricula can be built to enable students to progress from kindergarten through high school graduation. The CCSS were developed by the National Governors Association and the Council of Chief State School Officers. Their efforts were voluntary; their goal is nationwide adoption and implementation, which they believe will better inform instruction and lead to higher student achievement through "strong shared expectations" and collaboration and shared resources among educators (Achieve, Inc., 2010).
At the present time, states set their own standards; there is no federal mandate. Many states use the NCTM standards in the creation of their own standards.
At all grade levels, this standard encompasses the understanding and representation of numbers, number systems, and relationships among numbers. In middle school, this includes the ability to work with fractions, decimals, and percentages. Students are also expected to develop an understanding of large numbers and be able to use exponential and scientific notation.
Algebra covers patterns, relations, and functions, including the appropriate notation. Math programs should also enable students to develop and use models and to analyze change in various contexts. Middle school students should be able to use tables and graphs and demonstrate a basic understanding of the concept of variables.
Geometry concerns two- and three-dimensional shapes. At the middle school level, students should be able to understand lengths, perimeters, areas, and volumes, and use these measurements in the development of geometric ideas and relationships.
These standards foster progression through an understanding of measurable attributes and the tools, techniques, and formulas that are used. Students in grades six through eight should be able to use metric and U.S. systems of measurement, use formulas to determine areas of geometric shapes, and solve problems involving scale factors, ratios, proportion, and derived measurements for attributes such as density and velocity.
In grades K–12, students build an understanding of how to formulate questions that can be answered by data collection. In grades six through eight, students should be able to design studies and collect data, which they then represent graphically using items such as histograms and box plots. They will also interpret data by finding ranges, means, and percentiles.
In the following areas, NCTM does not provide specific standards for middle school students. All standards are prefaced with the words "Instructional programs from prekindergarten through grade 12 should enable all students to —."
These standards support the development of students' abilities to apply and adapt appropriate strategies for problem solving. Students should be able to reflect on the process of problem solving itself.
Students should recognize that proofs are a fundamental aspect of mathematics. Within that understanding, they should develop the ability to select and use various types of mathematical reasoning.
This standard calls for students to communicate their mathematical thinking in a coherent and clear way to teachers, peers, and others. Students should be able to express their ideas with the correct use of mathematical language.
This standard requires that students be able to demonstrate the interconnectedness of mathematical ideas and recognize and apply mathematics in other contexts.
Students should be able to use representations to organize, record, and communicate mathematical ideas. This will enable them to model and interpret physical, social, and mathematical phenomena.
