Mr. Fjelstrom's Algebra 2

Here is the review and solutions to the review. If you have any questions, you can post comments and I will answer them or come by after school Wednesday or Thursday.

We reviewed and retook benchmarks 24.1-4, and also 2.5-8. There are 2 review assignments (I will post them later). We will have another opportunity to retake these benchmarks (as well as 9.1 and 10.1) on Friday and Tuesday of next week.
REMINDER:
Tomorrow (Thursday, Dec. 8) is the last day for benchmark retakes. Doors close at 3:45.

Review 4.3 Cramer's Rule
4.4 Inverse of a Matrix
• 2x2 inverses
HW: #38 page 227 #17-29 (o)
Today is the last day of new stuff. Everything from here on out will be review (of course, there are only 3 class meetings left).
DON'T FORGET!!!!
Thursday is the last day for benchmark make-ups. The doors will close at 3:45. Be here before then if you play to make up any of them up!

As you can tell, the website got a face lift. Features are still the same with comments except for "Word Verification". This is a new feature to prevent some spam issues I was having. What do you think?

Action-packed day today. We took the practice final, 7 benchmarks, and I collected the grade report. The 7th benchmark was a surprise. I only put it on becuase I had room. We will take it again next week, at least 2 more times. Have a nice weekend.

Here is a link for function operations at Sparknotes. This site has great summaries, so it's worth bookmarking. There are even practice problems!
Also, I really like how they discuss inverses.

Because of the short day today, we only took benchmarks 9.1 and 10.1. No homework over Thanksgiving, so enjoy yourselves. Come back from the long weekend ready to buckle down and get the last few benchmarks (9 actually) out of the way and our first semester done.
Remember, Grade Report #4 is due Friday, Dec. 2. And that is the FINAL DAY to turn it in. That is also the day of 6 benchmarks and the practice final.

Happy Turkey Day!
