Post for February 19th

Hi everyone!

We finished chapter 5 today. Then we did part two of the activity about patterns of blocks, talked about slope, and did some exam review.

Next week is the second exam, so fire up for that! It'll cover chapters 3, 4, and 5. We've already done most of the stuff on chapter 3, but since it'll come up again in chapter 4 (graphing lines and solving linear equations) it's good to review.

The project is also due next week. Whee!

Here's the schedule for the rest of the term:

Next week (Feb 26th): exam in the morning, section 8.8 (more on functions) in the afternoon.

March 5th: sections 12.1-12.3 in the morning, redo exam and review in the afternoon.

March 12th: comprehensive final exam. That's the only thing scheduled for this day!



Here are some ideas for topics to review for next week's exam:

Graphing lines
Slopes and intercepts
Solving linear equations
Story problems with linear equations
Functions and function notation
Graphing systems of lines to find their intersection point (unless they're parallel or the same line)
Solving linear systems of equations
Story problems with systems of equations
Solving systems of linear inequalities by graphing
Exponents and exponent rules
Scientific notation
Polynomials and polynomial operations

Whew! It seems like a lot when I write it all out like that. Don't worry about dividing a polynomial by a polynomial - we'll only be dividing by one term (by a monomial).

And here are the page numbers for the exam review sections. My suggestion is to start with the cumulative review and then see where you need more practice.

Chapter 3 test: pages 302-304
Chapter 4 test: pages 372-373
Chapter 5 test: pages 464-465

Chapters 1-5 cumulative review: pages 466-467

I haven't given specific problems - practice as many as you need to. For some of us, that's just the cumulative review, and for some of us that's all 144 problems from the three chapter tests and the cumulative review - and maybe even more. But if you know how to do all the problems above you're ready for the exam.

Good luck and have fun,

-Dave
