[children contemplating a line]

Excellent math teachers have been far too scarce in American education. This course and its prequel, Math 1135, give you the keys to how and why elementary mathematics works. We will develop a thorough understanding of the ideas, how they are related to eachother, and how they are related to more advanced ideas. This is the basic knowledge which underpins truly great teaching!

Course Objectives

The course consists of fundamental topics in geometry and measurement. This includes the concepts of length, area, volume, angles, units of measurement, precision and error. Algebraic expressions and functions, primarily in the linear case, are introduced to express geometric relationships.

The basic properties of two and three dimensional geometric shapes and their relationships are a central part of the course. Special emphasis is put on geometric reasoning through problem solving, including unknown angle, length, area, and volume. The course also covers topics on transformations in the plane, symmetries, congruence, and similarity. Some geometric constructions and basic geometric proofs are included. The skills developed throughtout the course are applied at the end in a brief introduction to probability.

Topics

  • Informal and formal proofs with angles
  • Geometric constructions
  • Angle sum in triangles, polygons
  • Pythagorean Theorem statement and proof
  • Planar shapes
  • Linear equations and graphs
  • Algebra and linear equations
  • Measurement of length, area, volume
  • Units of measurement
  • Perimeter, area and volume of 2D and 3D shapes
  • Plane transformations: translations, rotations, dilations
  • Introduction to coordinate geometry
  • Introduction to probability

Learning goals

  • Understand concepts of length, area, volume and angles, units of measurement, precision and error.
  • Understand concepts of lines, angles, and geometric figures in two and three dimensions.
  • Fluency with derivation and application of area and volume formulas.
  • Understand geometric constructions and transformations in coordinate and coordinate-free geometry.
  • Understand how to use algebra to solve problems in geometry.
  • Familiarity with the concepts of theoretical and experimental probability.
  • Identify major historical developments in measurement and geometry, including contributions of significant figures and diverse cultures.

Textbook

Mathematics for Elementary Teachers with Activities, 4th Edition by Sybilla Beckmann. ISBN 0-321-82572-1. The 4th edition (Monkeys on the cover) is substantially improved over earlier editions. Moreover, it is available in electronic or loose-leaf formats which are cheaper and more portable than the bound version.

Attendance

Active participation in class is an essential part of this course, and so attendance every day is required. Please let Niles know as soon as possible if an illness or other commitment will prevent you from attending. Homework is due at the beginning of each class, and late homework cannot be accepted unless prior arrangements have been made. See full late policy below.

Calculators and Mathematical Software

There are a variety of modern tools which support mathematics learning and application. We'll use several of them in this course, but no technology will be used on the quizzes or exams. In particular, calculators and cell phones will not be permitted. The only materials you'll need are writing instruments and your mind.

Exam Schedule

We will have six in-class exams and a final exam; exam dates are given below. Please notify Niles immediately if you cannot be present for one of the exams.

Midterm Exams

  • Monday, January 23
  • Monday, February 06
  • Monday, February 20
  • Monday, March 06
  • Monday, March 27
  • Monday, April 10

Final Exam

Scheduled by the registrar. See the campus schedule for exam times.

Assessment

Your final grade will be based on written homework, written and oral in-class participation, quizzes, midterms, and a final exam. The precise breakdown is as follows:

  • In-class participation: 13%
  • Homework: 10%
  • Quizzes: 15%
  • Midterm exams: 42%
  • Final exam: 20%

Participation

Thoughout this semester we will be focused on the how and why of elementary mathematics. This means that you will be responsible both for knowing the content and for knowing how to explain the content. We will practice this in a variety of ways, and much of this practice will take place in class.

Teaching mathematics requires listening carefully to students, assessing their ideas, and responding in ways that make sense. Our class participation is designed to practice these essential skills. You will have opportunities on a daily basis to listen to your fellow classmates explain ideas and ask questions. You will be asked to respond with your ideas and with additional questions. Together we will see how and why mathematics works! Participating in this course includes all of the following:

  • Show interest in mathematical ideas.
  • Show interest in different ways of approaching mathematical ideas.
  • Listen carefully to different ways of solving a problem.
  • Carefully evaluate a proposed method of solution.
  • State whether you agree or (respectfully) disagree with a statement.
  • Show interest in learning with and from others.

Late Work Policy

If you miss class on the day homework is due, or forget to bring a printed copy of your homework, you may send me a copy by email the next day. I will accept up to three homeworks this way.

If you must miss class on the date of a quiz or exam, please do the following:

  • Contact me before the time of the assessment to let me know you will be away.
  • Provide a reason and objective documentation (e.g., a note from your health care provider).
  • Make up the assessment within two days of your return to campus, and before the next class if possible.
  • Miss no more than two assessments this way.

If you do each of the items above, you will have no penalty. For each item that you do not complete there will be a 10% reduction in your final score.

Exceptions may be made in the case of an emergency; please contact me as soon as you are able.

Grading Rubric

The descriptions on the rubric below are meant as a guide to help answer the question What constitutes a good explanation of mathematics? This is a subtle and challenging question—one that is worthy of considerable time and energy. As you write your explanations, consider the distinction between Procedure and Conceptual Meaning. A complete explanation addresses both of these, but the conceptual meaning is essential. Explanations that address procedure only are a disservice to students and do not support their future learning. They are also much less interesting!

G++
Exemplary
Excellent work that exceeds the assignment guidelines.
G+
Good plus (10)
Correct procedure with an explanation that effectively addresses relevant definitions and concepts.
G
Good (9)
Correct procedure with nearly complete explanation.
Em/G
Emerging/Good (8)
Well-developed but incomplete explanation.
Procedural errors are minor or nonexistant.
Em+
Emerging plus (7)
Emerging explanation that shows understanding.
Procedural errors are minor or nonexistant.
Em
Emerging (6)
Explanation that mentions core definitions or conceptual meaning relevant to the question.
Possibly some non-minor procedural errors.
R/Em
Relevant/Emerging (5)
Work that has merit but also has significant shortcomings in the procedure and/or explanation.
R
Relevant effort (3)
Work that shows relevant effort but is seriously flawed.
NC
No credit (0)
No work submitted, or no relevant effort shown.
