:Algebra: What it is and isn’t

Algebra is: A system (set of rules) for solving problems involving mathematics.Algebra is not: The only method to solve problems. In fact, every problem we do this year could be solved without algebra. It would take a lifetime to do it, though.

Understand this….

There are no Algebra problems. There are problems which can be solved easier by using Algebra as your solution system.

For example, let’s solve this problem without algebra first: Two more than the sum of three consecutive numbers is 200.

A Simple Algebra Rule Example

1. 8 + 7 = 15; 8 =

2. 15 – 7 = 8; 15 =

3. x + 7 = 15; x =

4. x - 7 = 8; x =

5. 8 * 4 = 32; 8 =

6. 32/4 = 8; 32 =

A. Notebook: Your notebook is to be divided into three sections: 1. Warm-Up 2. Formulas & Vocabulary 3. Class Notes & Practice ProblemsAlways begin your entry with the date. On most days, half of the warm-up exercises will be solved. The remaining problems will be graded on effort and correctness.

Your participation grade includes solving warm-up questions the board when called, and regularly teaching your partner the step-by-step solution to one of the assigned class work problems.

A Closer Look at the Syllabus:

Lunch-Time Service (LTS)The following are examples of actions/behaviors that qualify for LTS. You can bring work with you if you have, if not, I will provide you a short assignment: LTS occurs at the beginning of lunch that day. 4th period service is the following class day.

Example Time (minutes)Tardy: 15Water/Restroom 15Every 3rd class work not submitted 30Disruptive Behavior, Prohibited Items 15

Time doubles if no-show on 1st day, referral to Mr. Davis if no show for 2 days.
