MTH 144 Precalculus

Spring 2025

Disclaimer: This syllabus represents my current plans and objectives. As we go through the semester, those plans may need to change to enhance the class learning opportunity. Such changes, communicated clearly, are not unusual and should be expected.

Course Description

This course is primarily for students who intend to take MTH 145 Calculus and Analytic Geometry I. Precalculus topics include, but are not limited to: polynomial, rational, exponential, logarithmic, and trigonometric functions and equations, trigonometric identities, applications of trigonometry, conic sections, and sequences and series.

NOTE: Use of a specific graphing calculator will be integrated throughout the course. Contact EMPS Division Office for details. Students who earn a grade of C in MTH 108 must complete the yearlong sequence of MTH 122 College Algebra and MTH 123 Trigonometry as a prerequisite for MTH 145 Calculus and Analytic Geometry I. Students with credit for both MTH 122 and MTH 123 will not be given credit for MTH 144. Students may not receive credit towards degree for both (MTH 122 and MTH 144) or (MTH 123 and MTH 144).

Prerequisites

Geometry proficiency and MTH 108 (B or better) or an appropriate score on the CLC Math Placement Test, Math SAT, or Math ACT

Grading Overview

Your overall course grade will be based on your performance on the Homeworks, In Class Activities, Exams and Final Exam.

Exams

You will have fours exams and a mandatory cumulative final exam. You may not use books, notes, unauthorized calculators, phones, tablets, or software applications during the exams. Each exam is taken in class. Exams include vocabulary, short essay, and problems based on homework and notes. Exams are paper and pencil.

Exam dates are fixed and listed in the course schedule below. Mark these dates on your calendar now and plan accordingly - request time off work, arrange transportation, and avoid scheduling other commitments on these days. If you anticipate any conflicts, contact me immediately rather than waiting until exam day.

WebAssign Online Homework

Online homework will be assigned after each class session and is due by the start of the next class period. While assignments are designed to be completed between classes, you have until the following week as a final deadline to submit your work. Regular practice through homework is essential for mastering mathematical concepts - problems are carefully selected to reinforce your understanding and build computational fluency. If you find yourself struggling with the material, please utilize office hours, the math tutoring center, or email me to get help early rather than falling behind.

Written Homeworks

Written homework assignments are designed to develop proper mathematical notation and exam-ready problem-solving skills. You will submit these by scanning all pages into a single PDF using a scanning app and uploading to Canvas. Solutions will be posted 48 hours after the deadline, so no late work can be accepted. If you need an extension due to extenuating circumstances, email me before the deadline.

To address extenuating circumstances, one written assignment grade will be dropped.

In Class Group Activities

In class group activities can be in the form of a:

Group quiz: Group quizzes will be completed and submitted during class with randomly assigned teams. These hand-written assignments cover material from homework, notes, and the textbook, with all group members receiving the same grade. Group work provides valuable opportunities to both teach and learn from peers at different skill levels. Teaching others reinforces your own understanding, while learning from classmates offers fresh perspectives. This collaborative environment helps everyone succeed, as mathematics is inherently strengthened through teamwork and shared understanding.

Individual Quiz: Individual quizzes will be given throughout the semester and announced during the previous class period. These closed-note assessments are designed to familiarize you with exam-style questions and time constraints. Quizzes serve as checkpoints to ensure you're keeping pace with the material and give you targeted practice with the types of problems you'll encounter on exams.

Other activities: Throughout the semester, we'll engage in various interactive learning activities including games, Kahoot, and mathematical simulations. These activities are designed to reinforce concepts through collaborative learning and will be graded based on your active participation rather than correct answers. Showing up and engaging with the material is what matters for these assignments.

In class activities are meant to be done in class, thus one cannot make-up in class activities. However, some of each of the in class activities type grades will be dropped to account for unforeseen circumstances that prevent you from attending class.

Final Exam

The Final Exam is a cumulative final that covers all the material. The final is set up like the unit exams but covers more material. Final must be taken to receive a passing grade (A, B, C, or D).

Final Exam is on Wednesday, May 14 at 12pm-1:50pm.

Grade Distribution and Scale

Late Work Policies

Extensions will be granted on a case-by-case basis and is situation dependent. I understand that things come up, and communication is essential. Emailing me to communicate your situation (if possible before the missed class/assignment) is your responsibility, but not a guarantee of an extension. (csizemore@clcillinois.edu). There are no make-ups for in class activities but a few lowest grades will be dropped at the end of the semester. There is no make-up for exams. Three best exams scores out of the four semester exams will be kept. While this policy provides a safety net for an off day or unexpected circumstances, you should plan to take all four exams. Missing an exam intentionally removes your buffer against illness, emergencies, or underperformance on a later test. Be strategic - take every exam and give yourself the best chance at success in the course.

Withdrawing from the Class: There are 3 types of Withdrawals

Withdrawing from a class means that you no longer want to be enrolled in the class. Your transcript and the grade for the course may vary depending on the time at which you withdraw or request to withdraw from a course. The table below briefly outlines the actions you must take and the potential outcomes if you decide to withdraw from this course. I can help with understanding the difference. We can discuss different options if you are unsure.

The LGBTQ+ Resource Center facilitated program tangibly identifies safe allies for LGBTQ+ people in an effort to increase students' academic success and retention. I hereby declare myself as such an ally, and this class as a Safe Zone.

It is CLC policy for students to use whatever bathroom they wish to use on campus. This policy is supported by the gender-inclusive signs in front of every bathroom. There is also a single unit, gender-neutral bathroom stall in the C-wing on the first floor (C160A).

Student Rights and Responsibilities Policy (SRRP)

The Student Rights and Responsibilities Policy (SRRP) and associated procedures describe students' rights and responsibilities, as well as examples of misconduct inconsistent with the academic environment at CLC. For more information, refer to Student Rights and Responsibilities Procedures (PDF).

Title IX

The College of Lake County seeks to provide an environment that is free of bias, discrimination, and harassment.

You can also contact Kristin Jones, Title IX and Compliance Coordinator, at kjones24@clcillinois.edu or by calling (847) 543-2464.

Withdrawing from Class

You are responsible for dropping or withdrawing from classes you do not intend to complete. Grades of W will only be assigned to students who withdraw themselves. Tuition and fee refunds will be issued to eligible students based upon the effective date of withdrawal, which is recorded in the system at the time the student drops the class.

Instructors are required to administratively withdraw students who never attended or stopped attending class. All administratively withdrawn courses will remain on your academic record and are not eligible for a refund. Grades will be assigned based on dates of attendance:

• WN – You never attended class: no impact on GPA
• WS – You stopped attending class: no impact on GPA
• FW – You stopped attending class after the official withdraw deadline and your instructor deems you failing: equivalent of F grade for GPA.

In order to withdraw and receive a grade of W after the deadline, you must request a withdrawal from your instructor; requests must be made in writing and additional approvals may be required. You must have a passing grade at the time the withdrawal request is made. Once approved, you will be withdrawn from class.
