# Welcome to Math for Teachers!

NOTE: This is the syllabus for a PREVIOUS VERSION of the course. See nilesjohnson.net/teaching.html for current courses.

This is the course homepage and syllabus for Math 1136, Measurement and Geometry for Teachers. Here you will find our course calendar, current assignments, basic course information, and links to additional content of interest. This syllabus may need to be updated as the course progresses, and you will always find the current version at http://www.nilesjohnson.net/teaching/SP16/1136.html.

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.

## Basic information

### Instructor

Niles Johnson
Office: Hopewell 189
Office Hours: Mondays and Wednesdays 10:30 – 11:00 (in ECC); Thursdays by appointment

### 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.

### Exam Schedule

We will have three in-class midterms and a final exam. All students must take the exams at the scheduled times indicated here.

#### Midterm Exams (3):

Friday Feb. 05; Friday March 11; Friday April 08.

#### Final Exam:

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

### 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.

## 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: 12%
• Homework: 6%
• Quizzes: 13%
• Writing Assignments: 4%
• Midterm exams: 15% each, for a total of 45%
• 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.

### Homework and Quizzes

Homework and Quizzes will be scored using the rubric below. Scores are based both on mathematical correctness and quality of explanations. Homework should be typed and presented as you would an essay. If necessary, you may draw diagrams by hand on separate pages. Quizzes will be hand-written during the first 10 or 15 minutes of class.

The homework is intended to give you time to develop your explanations and understanding of the content. You are encouraged to work with your classmates on this, but you must write your own explanations. Homework is designed to help you learn, and not as an assessment tool. Therefore grades for homework will be recorded on a complete/incomplete basis (scores of 3 and higher are complete). The numerical scores are given only for your information.

The weekly quizzes are opportunities to evaluate your current grasp of the material. They will be very short and based on previous homework problems or class activities. Quiz grades will be recored as scored.

### 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.

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!

Quizzes and exams will follow this scale; Niles will use these for comments on homework too, although homework grades are recorded on a complete/incomplete basis. Homework will be considered complete if the average score is R (3) or higher.

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.
