3/25/09 – 2nd Block March 26, 2009

Today in class we went over Radicals. We started off reviewing the homework which was Pg. 31 25 -32 in the workbook we discussed problems 25, 26, 28, & 32. Mrs. Hawn demonstrated how to effectively operated different types of radical problems. We did a review game in class dealing with radicals. The game was called Difficulty, the purpose of the game was to prepare us for difficult radical problems. I actually like this new review game because it will prepare me and other students for the hard EOC test questions in June. Then we did a 3 Question Quiz at the end of class and I thought it was a little bit hard. – John Joseph

3/24/2009 Period 2. March 25, 2009

Today in Ms. Hawns’ class we started to review for our EOC exam which will be happening in 12 weeks, that time will come fast, so we need to start reviewing what we have learned from the beginning of the year. To start off with reviewing today we went over all different types of radicals. Ms. Hawn did an example of each type of radical that we have already learned. Some of the types that were mentioned are just a simple radical you have to factor completely and then find the groups and move them outside then leave the individual numbers inside. We also went over adding and subtracting, and multiplying radicals. Many people find that the multiplying radicals are more difficult, but they are basically the same thing except you are multiplying by then denominator to get the radical of the denominator. After we reviewed those all those types, we then received a 3 front and back page packet, and worked with our peers on it for the remainder of class. Tomorrow we will be having a 3 question quiz on the radicals that we reviewed today. I am so glad we are starting now, and taking the time that we have to go over all of the topics to refresh our memory.

2nd Block – 3/24/09 March 25, 2009

Today in class we have started our 2 Week Review Unit over various Algebra 2 Concepts. The concept that we went over today is Radicals, the different types of Radicals we went over were Simplifying, Multiplying, Dividing/Rationalizing, Adding & Subtracting, Equations. We took notes dealing with all types of Radicals and did a big review packet just dealing with Radicals. Know on how to solve Radicals.  I will do in example of how to solve a Simplifying Radical Problem.

Simplifying Radical Example) Square Root of 32 – Use the Factor Tree, then find to multiples that go into 32. For example 8 & 4 are multiples of 32. Then you breakdown the 2 multiples. 8 goes into 2 & 4. 4 goes into 2 & 2. The only number you can simple next is 4 because it goes into 2 & 2. Know collect like numbers but you can only do pairs of 2. There are only two pairs you can collect which are 2 2’s. Then you bring them out of the radical and each pair comes to one number so if you can a pair of 2’s they come to one 2. Then multiply them together which comes to 4. Then the number that didn’t get a pair stays in the radical. The answer is 2 Square Root of 2.

Thursday: March, 19, 2009 March 23, 2009

Reminder and recap of March, 19, 2009: Today in class Mrs. Hawn started out by reviewing any questions students had on are homework labeled applications of exponential functions. Then she went straight into are review game called matho, It turned out to be a great review, she answered any questions that students had on any of the problems up on the board. She also assigned three extra credit points for any student who got the definition of a half-life.  As well as gave us a parent /student project to be completed by next Monday (March, 23, 2009).

Review:  Mrs. Hawn explained that the test on Monday would consist of word problems; there were three different methods on how to solve each word problem correctly. 

The three methods on how to solve word problems:                                            

>Any word problems that contains the word Continuously well require the A=Pe^rt equation.

>Any word problems that contains the word Compounded  will require the A=(1+r/n)^nt equation.

>Any word problem that contains the word Half-life  will require the Y=a (1/2)^t/half-life equation.                                                                

} I found that the word problems at first were a bit challenging but when I figured out which method of solving best fit the word problem it became a bit more easier to understand.

Reminder to all student: our test that was scheduled for Friday (March, 20, 2009) has now been rescheduled for Monday (March, 23, 2009), Mrs. Hawn is also allowing you to still take the test as scheduled if wanted but you must notify her. So remember to take this extra time to study.  Have a great day! :]

3/17/08 – 2nd Block March 19, 2009

Today in class we reviewed over Base of e and Natural Logarithms which we started yesterday. We did a worksheet in class that was also collected for a grade. It had 12 problems on it dealing with Equations and Inequalities with the E and LN operation. An example of an equation dealing with the base of E and Natual Logarithms are e^4x = 120.  How to solve a Base of E is. Step 1 – Get the natural logarithm of both sides (ln e^4x =ln 120). Step 2 – The ln e on the left side of the equation cancels out and the exponent is no longer a exponent anymore.  (4x = ln 120). Step 3 – Get the natural logarithm of 120 which is 4.787. You do that by doing the ln operation on your calculator. To do that you need your graphing calculator. Then press the LN button next the 4 button. Plug in 120 and close the natural logarithm. Step 4 – Divide both sides ( 4x/4 = 4.787/4). Step 5 – x = 1.197. After that assignment was over we started something new with logarithms which is Simple Interest. We did a work sheet dealing with it and also Natual Logarithmic equations. – John Joseph

Today 3.17.09 :) March 19, 2009

Today in class, Mrs. Hawn checked homework and went over problems the class did not understand. I did not understand the complex logs with multiple steps and how to take an e and make it an ln and vis-versa, but now I do! For classwork, we completed a worksheet on complex logs and continued with the other logs we have learned. We also had a worksheet with our notes on it to finish in class. I understand fully now how to change the format of logs using the e and ln and am very ready for the test (whenever that is)! For homework tonight, we are to complete page 69 #29-47 Odd only. You also should review all notes and most importantly the worksheet we completed in class – #’s 10, 11, & 12, because of the 1?Quiz tomorrow.

Block 2

Pd. 2 March 17th. March 19, 2009

Today in class we did many things. To first start off, mrs. hawn answered any questions that we had on the homework last night, there were a few questions on the homework that were unclear, although mrs.hawn cleared it up for us. We did not have a one question quiz today. Although we did start a new lesson on Interest, and how to find the value of “t”  ”r” & “p”. The equation that you are supossed to use is I = Pe rt. After we learned how to get the value of it, we then moved on to learning problem solving with Interest. With problem solving it is bascially the same thing as finding the interest in an equation. No matter what you do you will always use  the formula I = Pe rt. Towards the end of class mrs. hawn distrubted progress reports, just to see where our grade stands as of right now. I am looking forward to tomorrow’s day in algebra 2

3/16/08 – 2nd Block March 17, 2009

Today in class we first started off reviewing the homework over the weekend which was Pg. 68 14 -17 in the workbook. Then we did a 1 question quiz on common logs which in opinion was pretty simple and easy. Next we did some practice problems over common logs. After that we took notes on other bases which is something different then what we were doing earlier in logs. – John Joseph

period 2: 3/16/09 March 17, 2009

Today in algebra 2 we learned a new topic with logarithms. Fist mrs. hawn went around to check our homework from over the weekend, and then we went over it, and asked any questions that we had before we had our one question quiz today. With the homework that we had, I personally thought it was fairly easy, but I was just unsure of a few things, but mrs. hawn cleared it up for the class, and i ended up getting a 7 out of 8 on the quiz. After we finished the 1 ? Q we  reviewed a few regular logrithm problems and then we went into our new lesson. Mrs. Hawn taught us about The Number e.  e = 2.7182818284.  The lograthims with base e are called natural lograthms. We also learned solving equations using common logarithms, and the inverse property of Base e and A natural Logarithms. for an example : e ^lnx = x.  With this lesson, i picked up fairly quickly with this, and would be well prepared for a quiz on this tomorrow. Also for our homework we had to do workbook page 69, numbers 1- 24 odd.

3-16-09: 3rd period March 17, 2009

today in class we started out by going over any questions from the homework from friday. then we moved on to have a 1 question quiz over common logs. after we did that we took notes over solving equations with logarithims on each side. after all that was done we had 15 minutes at the end of class to do whatever because we won it for having the best hw week.

Monday March 16,2009 March 17, 2009

Today in class we first had a homework check then went over questions from the homework to help review with our 1 question quiz that was on the concepts of log equations and solving them. Then, after you graded (i got a 100%) and gave them back  for us to look over our mistakes if there were any, we did a worksheet on Inverse property of Base e and Natural Logarithms.  We did the first 6 problems by ourself first and then did them on the board.  Then did 7 and 8 together as a class to discuss them.  These problems weren’t too difficult but you had to understand the process of solving, i enjoy this more than some of the other things we have done this year! Homework was in workbook on page 68 numbers 1-27 ODD!

Just incase anyone wanted to know!

3/13/09 – 2nd Block March 16, 2009

Today in class, we first started off reviewing last nights homework which was Pg. 68: 1 -13. I thought the homework was pretty straight forward and I ended up doing good on it also. Then we took notes to clarify some/several students confusion on the types of log problems. I too had some trouble on how to solve different log problems and I also thoguht it was very beneficial that we went over the different types of log problems. Then we did a practice activity which was board races on all the types of log problems. The homework for tonight is pg. 68 14 – 17 – John Joseph

2nd Block – 3/12/09 March 16, 2009

Today in class we first started off reviewing 2 sided logs. Then after that was over we took a 1 question quiz on 2 sided logs which in opinions was pretty easy and I think that I have mastered 2 sided log problems. Then we covered two practice problems again dealing with 2 sided logs. Then we started a new topic dealing with logs which is Common Logs. We took notes on topic and did some practice problems also. – John Joseph
