Thursday, December 10, 2009 Lesson #4-6: Least Common Multiple, pp. 144-145, problems 1-19. Students all have a handout that guides them through this lesson. We completed the majority of the lesson in class. Tomorrow students will make Accelerated Math corrections (if necessary) Tuesday, December 1, 2009 We completed an Accelerated Math Exercise on exponents. Almost everyone did very well. I handed out a worksheet on the powers of 10. Read the directions carefully, and then complete the page. It's just for fun, but the concepts are good to know. One student, who was absent yesterday, will need to complete the homework assignment, Lesson #4-1 (see below). Once this is understood, that student will be able to take the Accelerated Math Exercise. Monday, November 30, 2009 Lesson #4-1 Exponents, pp. 132-134, problems 1-34 Vocabulary Terms: Factor = a number used in a multiplication problem Produce = the answer to a multiplication problem Base = the number (factor) that is multiplied by itself when raised to a power Exponent = a number that tells how many times the base is used as a factor Power = the number of times a number is multiplied by itself *** A factor to the zero power is always 1 (see the pattern below) 2 to the 5th power = 32 2 to the 4th power = 16 2 to the 3rd power = 8 2 to the 2nd power = 4 2 to the 1st power = 2 2 to the zero power = 1 2 to the -1 power = 1/2 Thursday, November 19, 2009 The class took the Chapter 3 test today, so there will be no homework tonight. Tomorrow we will work on test corrections and logic problems. I am not assigning any homework over the Thanksgiving holiday. Our next chapter will be Number Theory and Fractions. If necessary, brush up on multiplication and division facts. Have a great holiday! Wednesday, November 18, 2009 Chapter 3 Test, p. 115. This will help to prepare you for the chapter test tomorrow. The answers are below. If you get one wrong, go back in the chapter to see how to find the right answer. 1. mean = 7 2. median = 5 3. mode = 6 4. range = 24 5. median = 24.5 books 6. mode = 26 books 7. range = 40 8. outlier = 48 The effect of excluding an outlier 9. median is less 10. mode is the same 11. range is less 12. double bar graph 13. (make your own graph) 14. No, during the third hour Station A plays more songs than Station B 15. 4th hour 16. 28 students 17. Sample Answer: change the scale for number of students to 5, 10, 15, etc. 18. Sample Answer: a school has more than 28 students 19. Biased; convenience sampling; students in Literature Club probably like reading more than most students do. 20. Biased; responses to a survey; students with a strong favorite were more likely to respond. Tuesday, November 17, 2009 Diagnostic Checkpoint, p. 114, problems 1-9. Remember to write the first four questions out in complete sentences. Chapter 3 Test Thursday Monday, November 16, 2009 Just a week to go before Thanksgiving. Hooray! Math Lesson#3-9: Representing a Point of View, pp. 112-113, problems 1-7, 9-11 We will have the Chapter 3 Math Test on Thursday. Friday, November 13, 2009 We have several students out with illness, so this is for them. Today we completed Lesson #3-8: Analyzing Statistical Results, pp. 108-110, problems 1-11. Carefully read the examples on p. 108 for direction. You will be looking for questions that are unbiased. That means that they contain neutral language and are fair. Thursday, November 12, 2009 We did not get too far in math class today due to the interruption of group pictures in the bowl. Lesson #3-7: Make a Graph, pp. 106-107, problems 1-9 Tuesday, November 10, 2009 Students worked on Accelerated Math today. Due to the fact that our copy machine is out of order, students were not able to see where they made errors. Everyone will get their TOPS report tomorrow so that errors can be corrected. No homework tonight. Monday, November 9, 2009 Lesson #3-6 Sampling Methods, pp. 103-105, problems 1-9 Most students completed this lesson in class and went on to respond to oral questions. Review the examples in the book. The bottom line is that random sampling is important for getting a relatively unbiased response. Convenience sampling (i.e., asking the choir about what kind of assembly they would want - music or sports - ) is biased as are surveys (generally only people who want to make a statement reply to a survey). Tuesday, November 3, 2009 Lesson #3-4: Choosing the Best Graph, pp. 96-97, problems 1-6 Remember: Choose BAR GRAPHS or PICTOGRAPHS to show numbers (If the graph is comparing one thing to another, use a DOUBLE BAR GRAPH) Choose LINE GRAPHS to show change over time Choose CIRCLE GRAPHS to show parts of a whole Monday, November 2, 2009 I believe that most students completed their homework in class today. Lesson #3-3: Stem-and-Leaf Plots, pp. 94-95, problems 1-14. Wednesday, October 28, 2009 Lesson #3-2: Data with Outliers, pp. 91-93, problems 1-9, 13, 17-24 An outlier is a value within a set of data that is far above or far below most of the other data. It can affect the median, but it usually has the greatest effect on the mean (average) of the set of data. Think of it as all of the ages of my math students with my age factored in. I am the outlier. I WILL BE GIVING ANOTHER CHAPTER 2 MATH TEST. THE BEST GRADE OF THE TWO WILL BE ENTERED INTO THE GRADEBOOK. BE SURE TO STUDY THOSE AREAS THAT YOU NEED TO STRENGTHEN. COMPLETE THE TEXTBOOK CHAPTER 2 TEST AGAIN ON PAGE 73, AND THEN CHECK YOUR ANSWERS ON THE OCTOBER 21ST LIST BELOW. Tuesday, October 27, 2009 Students were handed their Chapter 2 Tests. They will need to correct all errors on a separate piece of paper. Parents need to sign the test indicating that they saw it. We had quite a range of grades on this test, from 100s to fails. We will be revisiting these concepts again to ensure that everyone can master them. I WILL BE GIVING A CHAPTER 2 TEST AGAIN ON THURSDAY TO REINFORCE THE CONCEPTS. Tonight's homework is to to Set A on p. 118, and Set A on p. 121. This is on mean, median, mode, and range. To calculate the mean (average) add up all of the numbers. Make sure that decimal points are aligned. Then divide the sum of those numbers by the number of numbers added. This is the mean. To calculate the median, line up all of the numbers from least to greatest. The median for an odd number of numbers is the middle number counting in from each side. If there is an even number of numbers, the median is the average of the middle two numbers divided by 2. The mode is the most frequent number or numbers in a series of numbers. There may be one mode, more than one mode, or no mode. The range is the difference between the highest number and the lowest number. Thursday, October 23, 2009 We have spent the last 2 days taking the Chapter 2 Test. There is no homework for the weekend. Have fun! Wednesday, October 21, 2009 WE WILL HAVE THE CHAPTER 2 MATH TEST ON THURSDAY AND FRIDAY. YOU WILL GET THE FIRST HALF ON THURSDAY AND THE SECOND HALF ON FRIDAY. TO PREPARE YOU, COMPLETE THE FOLLOWING TEXT PAGES. IT IS ESSENTIAL THAT YOU CORRECTLY SHOW THE STEPS TAKEN TO ARRIVE AT A SOLUTION. Diagnostic Checkpoint, p. 72, all problems. Make sure to show your work. Chapter 2 Test in textbook, p. 73, all problems. Answers Below: Diagnostic Checkpoint: 1.) Commutative Property 2.) Property of Zero 3.) Distributive Property 4.) Identity Property 5.) m = 12 6.) p = 63 7.) n = 4 8.) z = 35 9.( j = 48 10.) y = 19.803 11.) d = 81 12.) s = 2.3 13.) Paige has saved $433.50 14.) Tara must wake up at 6:55 A.M. 15.) The distance around the track is 0.25 mile 16.) The number of adults who like walking is 3 times as great 17.) Exercises enjoyed by more than 150 adults are walking, biking, jogging Chapter 2 Test: 1.) 252 2.) 66 3.) 297 4.) 7,140 5.) n = 8; commutative property 6.) n = 8; distributive property 7.) 14,432 8.) 3,227.62 9.) 0.5894 10.) 0.038121 11.) 75.32 12.) 0.0008 13.) 4,572 14.) 411.8 15.) 45.25 16.) 130.75 17.) 320,000 18.) s = 224.4 19.) b = 675 20.) x = 8 21.) y = 9.4 22.) Alyce bought 6 carnations 23.) Rena needed 22 sacks 24.) 2 times 25.) with 12 icons Tuesday, October 20, 2009 Did anybody catch that I wrote down "Friday, October 19, 2009" for yesterday's homework. That must have been wishful thinking. Tonight's homework is Lesson #2-8: Using a Pictograph, pp. 70-71, problems 1-10. THE CHAPTER 2 TEST WILL BE GIVEN IN TWO PARTS THURSDAY AND FRIDAY. Make sure that you understand each of the concepts presented and that you can correctly show all work with equations. Refer back to the examples I gave you today. Monday, October 19, 2009 Lesson #2-7: Solving Multiplication and Division Equations, pp. 68-69, problems 1-17 and 20-26 evens. Show your proof on the even problems #2-26. Remember, to undo multiplication you need to divide (this is called the inverse operation). To undo division, multiply. Ex: 7W = 84 h __ = 35 7W = 84 4.6 __ __ 7 = 7 4.6 x h = 35 x 4.6 ___ __ W = 84 1 4.6 __ 7 h = 161 W = 12 (**Sorry, the fractions do not come out well with this program.) Your work must be extremely neat. Your work area should be to the far right on your paper. Thursday, October 15, 2009 Diagnostic Checkpoint, p. 64 all problems Wednesday, October 14, 2009 Complete Accelerated Math corrections Tuesday, October 13, 2009 Lesson #2-5: Divide a Decimal By A Decimal, pp. 62-63, problems 1-20 (with proof) and then problems 21-31 odds. Division is a long, and sometimes tedious, process. Keep your work neat and in straight columns. We will have an Accelerated Math page tomorrow. Friday, October 9, 2009 No homework assigned. Thursday, October 8, 2009 Lesson #2-4: Dividing With Whole Numbers, pp. 58-61, ***Complete all problems #1-30, THEN you may choose to do the evens or odds for problems 31-50. REMEMBER, I will not be in class tomorrow. I will be on campus at a training session, but you will have a substitute. I expect that all students will be on their best behavior. Thank you, Wednesday, October 7, 20009 We completed an Accelerated Math Exercise today based on multiplying whole numbers and decimals. Tonight's homework: Lesson #2-3: Interpreting the Remainder, pp. 56-57, problems 1-5 REMEMBER TO READ THE PROBLEMS CAREFULLY TO MAKE SURE YOU REALLY KNOW HOW TO INTERPRET THE REMAINDER. Tuesday, October 6, 2009 Lesson #2-2: Multiplying Whole Numbers and Decimals, pp. 52-54, problems 6-26. Remember that you do not line up the decimals. Multiply as usual. Then look at the factors being multiplied and count the number of places to the right of the decimals. Count from the right of your product the number of places. Monday, October 5, 2009 Lesson #2-1: Multiplication Properties, pp. 50-51, problems 7-23. Friday, October 2, 2009 Students were handed their Chapter 1 Math Tests. Everyone completed an error analysis and discussed where they need to focus their attention. The overall grade average was 85%. While that is pretty good, I know that the average can be much higher. Very few errors were the result of not understanding the concepts. Many were simple oversights. The math test must be signed by a parent and returned on Monday. Have a good weekend. Thursday, October 1, 2009 Today was Chapter 1 Test day. I know everyone studied hard, so there is no homework for this evening. I hope to have the scores posted by this afternoon. Wednesday, September 30, 2009 (Yesterday was the 29th...) Prepare for Chapter 1 Test that will be given tomorrow. It is a 30 question test that will require showing all work. Students will need to be on time and work efficiently in order to finish by the end of class. The Chapter Test will include the following: Write the value of an underlined digit in short word form (Remember, this means using a number AND a number. ex: the value of 7 in 47,086 is 7 thousands) Write a number in standard form (this means plain old numbers) Compare numbers using <, >, or = (you must write out the entire number phrase in order to receive full credit. Simply writing <, >, or = will receive only 1/3 credit) Write decimals in order from least to greatest (align those decimals) Round numbers to an underlined place value position (Remember, if the number to the right of the underlined place is 5 or more, you will need to add 1 to the underlined value. Be careful when the underlined number is a 9. Ex: 8.3797 requires adding 1 to the 9. You need to regroup by adding 1 to 9 and then carrying the tens digit over to the 7. 8.3797 rounds to 8.380 Add or subtract decimals. (You must show all of your work. Remember to line up the decimals and pay careful attention to the signs) Order of Operations (Remember PEMDAS, and show your pizza...The example will be on the whiteboard) Evaluate expressions (more pizzas) Write expressions (Remember to keep things in proper order. Remember what to do when you have the word "than") Solve equations (Show all steps of the problem in a neat and orderly manner. Follow PEMDAS. PROOF will be required to earn full credit) Know the properties of addition. (associative, commutative, identity - SPELLING WILL COUNT) Use a bar graph to answer questions IN COMPLETE SENTENCES. Students should review for the test using the Chapter 1 Test on p. 35. The answers to p. 35 are below: 1.) 160,248.3710 2.) 8 millions 3.) 2,050 4.) 2.001121 > 2.00112 Estimates may vary: 5.) 111,000; 111,659 6.) 9; 8.6918 7.) $1,800; $1,775.95 8.) 430,000; 435,749 9.) 39 10.) 40 11.) 31 12.) 21 13.) 4 14.) 43 15.) n - 2 16.) 6(n + 2) 17.) x = 7 18.) p = 37 19.) m = 34 20.) r = 82 21.) Yes; the pattern follows a 7-day schedule, so Bobbie will start each Monday swimming. 22.) About 344 seats; an estimate; it was stated that about half the seats were full; this is an approximation 23.) The difference is about 0.5 ft. Good Luck on your test tomorrow. You can do it! Tuesday, September 28, 2009 Diagnostic Checkpoint p. 34. This page will help students monitor progress by checking performance on content presented since the previous Diagnostic Checkpoint. Students should refer back to the lessons if there is something that is confusing to them. WE WILL BE HAVING A CHAPTER ONE MATH TEST ON THURSDAY. IT WILL TEST THE CONCEPTS REVIEWED AND TAUGHT IN THE ENTIRE CHAPTER. Friday, September 25, 2009 Good work today on the Accelerated Math. It was tricky. No other homework, but there will be a Chapter 1 Test next Thursday. Enjoy your long weekend! Thursday, September 24, 2009 Lesson #1-12: Solving Addition and Subtraction Equations, pp. 30-31, problems 6-28. Remember the steps to solving addition and subtraction equations. You first want to write down the problem. If you wish to change the order around, do keep each side of the equation in the same order as the original problem Next, isolate the variable by using inverse operations. Remember that whatever you do on one side of the equal sign must be done on the other side. Ex: x - 22 = 66 Do not forget to show your proof. x - 22 = 66 + 22 +22 88 - 22 = 66 ___________ x = 88 ALGEBRA NEEDS TO BE A WORK OF ART :) Wednesday, September 23, 2009 Lesson #1-11: Writing Expressions, pp. 28-29, problems 5-21 REMEMBER that when a phrase uses the word THAN, you will need to reverse the order of the expression. For example, 6 LESS THAN K would be written k - 6, 6 MORE THAN THREE TIMES A NUMBER N would be written 3n + 6. I will be doing a notebook check on Friday. All students must have a binder that has sections for Notes, Homework, Accelerated Math, and Quizzes/Tests. Tuesday, September 22, 2009 First, make all corrections on your Accelerated Math. You have the correct answer on your TOPS report, but make sure you can understand how you made your error(s). You will be asked to explain tomorrow. Many times, your errors will only be bubbling problems or small oversights. If you truly do not understand how you made a mistake, we will sort it out tomorrow. Complete Lesson #1-10: Variables and Expressions, pp. 26-27, problems 10-34 Remember: A VARIABLE varies or changes An EXPRESSION is a phrase or part of a sentence A SUBSTITUTE takes the place of something EVALUATE means to find a value or numerical amount. 1.) In n=3, then SUBSTITUTE the number 3 for n. 2.) Use operations to EVALUATE 2n + 5. 3.) 2n + 5 is an EXPRESSION. 4.) In 2n + 5, the n is a VARIABLE. Monday, September 21, 2009 Lesson #1-9 Order of Operations, pp. 24-25, problems 6-24 Remember PEMDAS = Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. Review the Order of Operations rules in the box on p. 24 of your math text. Accelerated Math grade tomorrow. Friday, September 18, 2009 Happy Friday! I would like to thank all of you who were able to attend the Back to School Night last night. For those of you who were unable to attend, just email any questions or comments. There is no homework tonight other than correcting Accelerated Math errors. Make sure that you can explain where you made your mistakes. Happy Weekend Thursday, September 17, 2009 Correct any errors on Diagnostic Checkpoint Review lessons #1-1 through #1-7 - Math Quiz Friday We started Accelerated Math today. Wednesday, September 16, 2009 Diagnostic Checkpoint, p. 20, problems 1-31 We will begin using Accelerated Math tomorrow in addition to the textbook. Tuesday, September 15, 2009 Lesson #1-6: Adding Whole Numbers and Decimals, pp. 14-16 PROBLEMS 8-30 EVENS ONLY Lesson #1-7: Subtracting Whole Numbers and Decimals, pp. 17-19 PROBLEMS 10-42 EVENS ONLY (We had time in class to work on these assignments) Monday, September 14, 2009 Lesson #1-5: Rounding Whole Numbers and Decimals, pp. 12-13, problems 5-23 Friday, September 11, 2009 Wheeee!!!! No Homework Thursday, September 10, 2009 HW #1-4: Addition Properties, pp. 10-11, problems 6-23 Make sure that you show all of your work.
Or, would you like to view and optionally restore one of these previous versions?
