# 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 1135, Number and Operations 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/AU18/1135.html.

These students are using place value and the meaning of addition to understand multi-digit arithmetic.

Excellent math teachers have been far too scarce in American education. This course and its sequel, Math 1136, 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

This course covers the concepts of whole numbers (positive and negative), place value (base-ten and alternate bases), decimals, and fractions. Some content on irrational numbers appears at the end, and this is extended in Algebra and coordinate geometry for teachers (2137). The four arithmetic operations are covered both conceptually and algorithmically. Attention is given to ensuring that students can perform the algorithms correctly and explain why they give accurate answers. Lastly, the course covers the concepts of proportions and how they are related both to multiplication/division and to fractions. Factors, divisibility, and some elementary number theory complete the course.

### Topics

• Counting numbers, decimals
• Meaning of fractions
• Meaning of addition and subtraction
• Meaning of multiplication
• Multiplying fractions, decimals, integers

#### Office Hours

• Mondays and Wednesdays 2:15 – 3:45
• Other days/times by appointment

### Textbook

Mathematics for Elementary Teachers with Activities, 5th Edition by Sybilla Beckmann. ISBN-13 9780134392790 (bound) or 9780134800196 (loose leaf, recommended). The 5th edition (peacock on the cover) and 4th edition (monkeys on the cover) are reasonably similar, so either one will be sufficient for this class.

We will use the activities every day in class. Most students prefer the loose-leaf format so that they can bring only the part they need with them; I recommend it. Note that this class and its sequel, Math 1136, will both use this text, so it is worthwhile to purchase instead of rent.

### 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. We will answer questions about homework at the beginning of class, and you can upload your homework after class on the day it's due.

### 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

• Wednesday, September 05
• Wednesday, September 19
• Wednesday, October 03
• Wednesday, October 17
• Wednesday, October 31
• Wednesday, November 14

### 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.

### Homework

The homework in this class 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.

Homework should be typed, with explanations using complete sentences, as you would an essay. Homework is turned in by uploading it to Carmen -- please let Niles know if you have any trouble with this. If necessary, you may draw diagrams by hand on separate pages and upload a picture or scan.

### Quizzes

We will have short in-class quizzes each Friday. These will usually be just one or two questions, and they give you a chance to evaluate your current grasp of the material. The quiz questions are based on previous homework problems or class activities. Quizzes are scored on a 10-point scale.

It is generally not possible to make up quizzes if you miss one. Instead, the lowest two quiz scores will be dropped at the end of the term. For students with extended illness or other recurring conflicts, exceptions may be made on a case by case basis -- contact Niles to discuss your situation.
