Course Overview

Algebra is an area of mathematics that permits us to describe and model the real world. You will explore the big ideas of algebraic thinking that are currently taught in elementary and middle schools in the United States. You will complete activities that build conceptual understanding between and among these big ideas. Topics covered include properties of real numbers, mental math, equal vs equivalent, growing patterns, functions, linear and non-linear models, recursive functions, linear inequalities and systems, and simplifying, combining, evaluating and factoring quadratic expressions and equations.



Technology Requirements

Participation in this course will require the basic technology for all online classes at Columbia College:
  • A computer with reliable Internet access
  • A web browser
  • Acrobat Reader
  • Microsoft Office or another word processor such as Open Office

Week 1: Real Numbers
Readings
  •  Developing Essential Understanding of Algebraic Thinking: pp. 1-24

Introduction Discussion
Tell us a little about yourself. Items you might share are your interest in math, your career ambitions or family. Let's get to know each other! (Reminder: Two responses are expected in this and all discussions.)
Discussion 1
 The concepts of even and odd numbers seem to be simple to us, but for children this may not always be the case.

Watch the video clip at this University of Michigan site and respond.  You can use these questions to help, but feel free to respond in other ways.

1.  Were you surprised by the students' various interpretations of odd and even numbers?

2. What do you think is the importance of allowing the students to share and defend their thinking?

3. What role is the teacher playing in the classroom?

4. Is this how you remember learning about even and odd numbers and or what you have seen in the classrooms?

5. Why do you think the teacher is letting the kids develop the definition?  (i.e. They have a working definition of even number)

Homework 1
Homework 1 covers sum and products charts, classifying real numbers, and properties of real numbers

Course Policies

Student Conduct

All Columbia College students, whether enrolled in a land-based or online course, are responsible for behaving in a manner consistent with Columbia College's Student Conduct Code and Acceptable Use Policy. Students violating these policies will be referred to the office of Student Affairs and/or the office of Academic Affairs for possible disciplinary action. The Student Code of Conduct and the Computer Use Policy for students can be found in the Columbia College Student Handbook. The Handbook is available online; you can also obtain a copy by calling the Student Affairs office (Campus Life) at 573-875-7400. The teacher maintains the right to manage a positive learning environment, and all students must adhere to the conventions of online etiquette.

Plagiarism

Your grade will be based in large part on the originality of your ideas and your written presentation of these ideas. Presenting the words, ideas, or expression of another in any form as your own is plagiarism. Students who fail to properly give credit for information contained in their written work (papers, journals, exams, etc.) are violating the intellectual property rights of the original author. For proper citation of the original authors, you should reference the appropriate publication manual for your degree program or course (APA, MLA, etc.). Violations are taken seriously in higher education and may result in a failing grade on the assignment, a grade of "F" for the course, or dismissal from the College.

Collaboration conducted between students without prior permission from the instructor is considered plagiarism and will be treated as such. Spouses and roommates taking the same course should be particularly careful.

All required papers may be submitted for textual similarity review to Turnitin.com for the detection of plagiarism. All submitted papers may be included in the Turnitin.com reference database for the purpose of detecting plagiarism. This service is subject to the Terms and Conditions of Use posted on the Turnitin.com site.

Non-Discrimination

There will be no discrimination on the basis of sex, race, color, national origin, sexual orientation, religion, ideology, political affiliation, veteran status, age, physical handicap, or marital status.

Student Accessibility Resources

Students with documented disabilities who may need academic services for this course are required to register with the office of Student Accessibility Resources. Until the student has been cleared through this office, accommodations do not have to be granted. If you are a student who has a documented disability, it is important for you to read the entire syllabus as soon as possible. The structure or the content of the course may make an accommodation not feasible. Student Accessibility Resources is located in Student Affairs in AHSC 215 and can be reached by phone at (573) 875-7626 or email at sar@ccis.edu.

Online Participation

You are expected to read the assigned texts and participate in the discussions and other course activities each week. Assignments should be posted by the due dates stated on the grading schedule in your syllabus. If an emergency arises that prevents you from participating in class, please let your instructor know as soon as possible.

Attendance Policy

Attendance for a week will be counted as having submitted any assigned activity for which points are earned. Attendance for the week is based upon the date work is submitted. A class week is defined as the period of time between Monday and Sunday (except for week 8, when the work and the course will end on Saturday at midnight.) The course and system deadlines are based on the Central Time Zone.

Cougar Email

All students are provided a CougarMail account when they enroll in classes at Columbia College. You are responsible for monitoring email from that account for important messages from the College and from your instructor. You may forward your Cougar email account to another account; however, the College cannot be held responsible for breaches in security or service interruptions with other email providers.

Students should use email for private messages to the instructor and other students. The class discussions are for public messages so the class members can each see what others have to say about any given topic and respond.

Late Assignment Policy

An online class requires regular participation and a commitment to your instructor and your classmates to regularly engage in the reading, discussion and writing assignments. Although most of the online communication for this course is asynchronous, you must be able to commit to the schedule of work for the class for the next eight weeks. You must keep up with the schedule of reading and writing to successfully complete the class.

No late discussion posts will be accepted. However late initial posts may receive partial credit provided they are posted before the end of the week deadlines (Saturdays).

Late exams are not accepted without prior approval. Approval is only given under significant extenuating circumstances and must be requested before the due date.

I do not accept late weekly quizzes.

I do accept late dropbox assignments, but will deduct 5% for each day they are late.

Course Evaluation

You will have an opportunity to evaluate the course near the end of the session. A link will be sent to your CougarMail that will allow you to access the evaluation. Be assured that the evaluations are anonymous and that your instructor will not be able to see them until after final grades are submitted.

Proctor Policy

Students taking courses that require proctored exams must submit their completed proctor request forms to their instructors by the end of the second week of the session. Proctors located at Columbia College campuses are automatically approved. The use of ProctorU services is also automatically approved. The instructor of each course will consider any other choice of proctor for approval or denial. Additional proctor choices the instructor will consider include: public librarians, high school or college instructors, high school or college counseling services, commanding officers, education service officers, and other proctoring services. Personal friends, family members, athletic coaches and direct supervisors are not acceptable.
