Discrete mathematics is the branch of mathematics that deals with arrangements of distinct objects. It includes a wide variety of topics and techniques that arise in everyday life, such as how to find the best route from one city to another, where the objects are cities arranged on a map. It also includes how to count the number of different combinations of toppings for pizzas, how best to schedule a list of tasks to be done, and how computers store and retrieve arrangements of information on a screen. Discrete mathematics is the mathematics used by decision-makers in our society, from workers in government to those in health care, transportation, and telecommunications. Its various applications help students see the relevance of mathematics in the real world.

STANDARD 15 All students will develop an understanding of the conceptual building blocks of calculus and will use them to model and analyze natural phenomena.

Descriptive Statement

The conceptual building blocks of calculus are important for everyone to understand. How quantities such as world population change, how fast they change, and what will happen if they keep changing at the same rate are questions that can be discussed by elementary school students. Another important topic for all mathematics students is the concept of infinity - what happens as numbers get larger and larger and what happens as patterns are continued indefinitely. Early explorations in these areas can broaden students' interest in and understanding of an important area of applied mathematics.

STANDARD 16 All students will demonstrate high levels of mathematical thought through experiences which extend beyond traditional computation, algebra, and geometry.

Descriptive Statement

High expectations for all students form a critical part of the learning environment. The belief of teachers, administrators, and parents that a student can and will succeed in mathematics often makes it possible for that student to succeed. Beyond that, this standard calls for a commitment that all students will be continuously challenged and enabled to go as far mathematically as they can.

Cumulative Progress Indicators

By the end of Grade 12, students:

  1. Study a core curriculum containing challenging ideas and tasks, rather than one limited to repetitive, low-level cognitive activities.

  2. Work at rich, open-ended problems which require them to use mathematics in meaningful ways, and which provide them with exciting and interesting mathematical experiences.

  3. Recognize mathematics as integral to the development of all cultures and civilizations, and in particular to that of our own society.

  4. Understand the important role that mathematics plays in their own success, regardless of career.

  5. Interact frequently with parents and other members of their communities, including men and women from a variety of cultural backgrounds, who use mathematics in their daily lives and occupations.

  6. Receive services that help them understand the mathematical skills and concepts necessary to assure success in the core curriculum.

  7. Receive equitable treatment without regard to gender, ethnicity, or predetermined expectations for success.

  8. Learn mathematics in classes which reflect the diversity of the school's total student population.

  9. Be provided with opportunities at all grade levels for further study of mathematics, especially including topics beyond traditional computation, algebra, and geometry.

  10. Be challenged to maximize their mathematical achievements at all grade levels.

  11. Experience a full program of meaningful mathematics so that they can pursue post-secondary education.

STANDARD 17 All students' mathematical learning will embody the concept that engagement in mathematics is essential, and that decision-making, risk-taking, cooperative work, perseverance, self-assessment, and self-confidence are frequently keys to success.

(This "learning environment standard" was developed and approved by the task force that prepared the Mathematics Standards and appears in the Introduction to the Mathematics Standards chapter of the New Jersey State Department of Education's Core Curriculum Content Standards; however, since it was not considered a "content standard," it was not presented to the New Jersey State Board of Education for adoption.)

Descriptive Statement

Engagement in mathematics should be expected of all students, and the learning environment should be one where students are actively involved in doing mathematics. Challenging problems should be posed and students should be expected to work on them individually and in groups, sometimes for extended periods of time, and sometimes on unfamiliar topics. They should be encouraged to develop traits and strategies - such as perseverance, cooperative work skills, decision-making, and risk-taking - which will be key to their success in mathematics.

Cumulative Progress Indicators

Experiences will be such that all students:

  1. Demonstrate confidence as mathematical thinkers, believing that they can learn mathematics and can achieve high standards in mathematics, and accepting responsibility for their own learning of mathematics.

  2. Recognize the power that comes from understanding and doing mathematics.

  3. Develop and maintain a positive disposition to mathematics and to mathematical activity.

  4. Participate actively in mathematical activity and discussion, freely exchanging ideas and problem-solving strategies with their classmates and teachers, and taking intellectual risks and defending positions without fear of being incorrect.

  5. Work cooperatively with other students on mathematical activities, actively sharing, listening, and reflecting during group discussions, and giving and receiving constructive criticism.

  6. Make conjectures, pose their own problems, and devise their own approaches to problem solving.

  7. Assess their work to determine the effectiveness of their strategies, make decisions about alternate strategies to pursue, and persevere in developing and applying strategies for solving a problem in situations where the method and path to the solution are not at first apparent.

  8. Assess their work to determine the correctness of their results, based on their own reasoning, rather than relying solely on external authorities.

STANDARD 18 All students will be evaluated using a diversity of assessment tools and strategies to provide multiple indicators of the quality of every student's mathematical learning and of overall program effectiveness.

(This "learning environment standard" was developed and approved by the task force that prepared the Mathematics Standards and appears in the Introduction to the Mathematics Standards chapter of the New Jersey State Department of Education's Core Curriculum Content Standards; however, since it was not considered a "content standard," it was not presented to the New Jersey State Board of Education for adoption.)

Descriptive Statement

A variety of assessment instruments should be used to enable the teacher to monitor students' progress in understanding mathematical concepts and in developing mathematical skills. Assessment of mathematical learning should not be confined to intermittent standardized tests. The learning environment should embody the perspective that the primary function of assessment is to improve learning.

Cumulative Progress Indicators

Experiences will be such that all students:

  1. Are engaged in assessment activities that function primarily to improve learning.

  2. Are engaged in assessment activities based upon rich, challenging problems from mathematics and other disciplines.

  3. Are engaged in assessment activities that address the content described in all of New Jersey's Mathematics Standards.

  4. Demonstrate competency through varied assessment methods including, but not limited to, individual and group tests, authentic performance tasks, portfolios, journals, interviews, seminars, and extended projects.

  5. Engage in ongoing assessment of their work to determine the effectiveness of their strategies and the correctness of their results.

  6. Understand and accept that the criteria used to evaluate their performance will be based on high expectations.

  7. Recognize errors as part of the learning process and use them as opportunities for mathematical growth.

  8. Select and use appropriate tools effectively during assessment activities.

  9. Reflect upon and communicate their mathematical understanding, knowledge, and attitudes.


* Note that in the Core Curriculum Content Standards of the New Jersey State Department of Education, the Mathematics Standards are numbered 4.1, 4.2, 4.3, etc., since they are preceded by standards in three other content areas.
