3rd Period: 12/18/08 December 19, 2008

In class today, we basically reviewed what we did in class yesterday. Mrs. Hawn went over how to multiply matrices with variables in them and how to find the inverse of matrices.

For example, to solve matrices with variables in them, all you so is solve the equation. so if you have a matrix with x+2 on the top and y+7 on the bottom then you would just make an equation with the other numbers on the other matrix. So if you had 12 and 17 in the other matrix, then you woul solve x+2=12 and y+7= 17. So then x and y would =10.

To find the inverse of a matrix you type the matrix in your calcualtor and put it to the -1 power.

After we reviewed the homework about this then we played a review game on inverse of matrices and then she went over some of the questions that would be on the quiz today.

I thought that the quiz was easy. It kind of made it easier that she went over everything that was going to be on the quiz before we took it so that was a huge help.

Period 2: 12/16/08 December 19, 2008

today we learned how to transform graphed triangles using matrices.  we started with transitions which is done by adding your shape’s points to how ever many spaces your moving the shape left/right and up/down. example: right 4, up 7 {(3,4), (-1,2), (-2, 4)} +  {(4,7), (4,7), (4,7)}. after learning this we went back to some old stuff like absolutes (|x|=3). it looks as though the whole class is getting the hang for matrices. i believe that mrs hawn will be pleased with our class in the next few days.

Classroom Wishlist December 15, 2008

Our classroom is in need of the following items:

• AAA batteries (for calculators)
• colored dry erase markers (for Mrs. Hawn)
• fine point dry erase markers (for students)
• tissues
• colored markers
• colored pencils
• individually wrapped candy (for students)

2nd period: 12-10-08 December 11, 2008

today we did our warm up of three problems that are focus onthe absolute value equation solving that were going to see in our test, thenwe went to a fun game of absolute value equation like solving 3=|x| which is the to 3,-3 after about seven problems

we added up the points and my group won and with that

i know that my group is going to pass this test and make miss hawn happy with our grade.

block 2: 12-9-08 December 10, 2008

Today in mrs. Hawns class, firstwe had a homework check from the night before. Then we had a warm up that was reviewing for what we have already learned so far, and also which will be on our test that is on Thursday. After that we had class work which was we got to work with a partner or 2 on the back of  our homework last night. Which was absolute value inequalities. We had to comple numbers 1-7.  Then we got to start our homework which was  more work with the absolute value inequalities, on work book page 6, numbers 14 though 18

3rd period: 12/8/08 December 9, 2008

First in class today we did a worksheet on solving inequalities. Some of the problems were like

a. {x|x < -3} = (-00, -3)

b. {x|x ≥ 5 } = (5, 00)

c

then there were word problems where we had to write the inequality.

a. there are fewer than 600 students in the senior class = 600 > x

b. to participate in a concert, you must be willing to attend at least ten rehearsals. 10 ≤ x

there were a few exercises on the worksheet as well, such as

1) ethan is reading a 482 page book for a book report due mon. he has already read 80 pages. he wants to figure out how many pages per hour he needs to read in order to finish the book in less than 6 hours.

write an inequality to describe the situation –> 482-80 ≤ x over six

solve and interpret the situation –> 67 ≤ x

2) four friends plan to spend friday evening at the bowling alley. 3 of the friends need to rent shoes for 3.50 a person. a game of bowling costs 1.50 a person. if the friends pool their 40 dollars, how many games can they afford?

a. write equation to describe situation –> 10.50 + 6x ≤ 40 because 3 x 3.30 = 10.50 & the number of games they want to play is unknown

b. solve & interpret situation –> -10.50 -10.50

—————————–

6x ≤ 29.50

then divide both by six and you get x ≤ 4.916

after that we did another worksheet on absolute value inequalities!

the work we did is difficult to type out but basically it was the same thing and we had a number line. i have difficulty with the number line because i get confused on where i’m supposed to shade it and all that.

umm always check your work the end

1st block-12/8/08 December 9, 2008

Today in class, we started off with Ms. Hawn checking our homework. While she was doing that we we’re working on a warm up, which were on simplifying radicals. That helped me really refresh my memory on that. After that Ms. Hawn gave us a worksheet on solving inequalities. It was a little hard for me, but luckily I got to work with my group and they helped me out. The most difficult was the word problems, but once Ms. Hawn explained it more to my group and I, it made more sense. After that we did that she gave us worksheet that was a little different to the solving inequalities worksheet. We had to use absolute value for the word problems. We had to try to do 1-3 for our homework.

1st period: 12/4/08 December 5, 2008

We went over our warm-up50 at the beginning of class.  It consisted of review on synthetic division and putting it in formation so that it can be solved. the second half of the warm-up dealed with getting your x values and showing them on the number line pointing in the right direction.  then we went over absolute value notes.on example showed (x + 3)=10 and how it has to be put into 2cases.   so one problem leaves the equation equal to 10 and the other case equal to negative -10.  then you check the equation by putting in the X’s in each case to check if it’s accurate.  I liked the method of solving in algebraic form because it’s a easier form for me because I like equations and numbers when solving things.  I didn’t really understand when entering it in the calculator and trying to find the two x value points and when doing this I get confused.  we also solved two step equations with absolute value.  we also broke up into groups of up to three to four.  and went up to the board solving equations.  by doing this, it helped allot of other people understand it better including me.

3rd period 12/3/08 December 5, 2008

today we stated on absolute value  functions.  we also did a group project as class work.  for example 2(x-3)+2  then you find the trans, domain, range, x.y,vertex.

12-2-08: 3rd period December 5, 2008

Today in class we reviewed

1st period: Nov. 25, 2008 December 2, 2008

Took a test on Radical Equations and Inequalities. The steps for solving radical equations are as follows:

1. Isolate the radical

2. Eliminate the radical by raising to power of index

3. Solve for x

4. Check

The test was mostly comprised of these problems as well as some review questions. Most of it was pretty cut-and-dry.  I may have confused methods when dealing with inequalities as opposed to equations.

11/24/08- 1st period December 2, 2008

Today in class we played a review game that was based on the game Family Feud.  In the review game we reviewed radical inequalities, domain and range, equations, and transitions.  The part that I had the hardest time with was the tranisitions because of remembering what each number in the equation stands for, whether it it flips, moves left or right, or up and down.  After I was able to memorize which number or symbol stood for transitions were much easier.  My favorite is domain and range.
