small medium large Thursday, November 20, 2008 We are going to have the Chapter 3 math test on Friday. Because there are other tests given on the same day, it is important to use your time wisely. With this chapter of information, having a full week of turkey and family fun will be all the better knowing that you did your best on the concepts presented. Complete the Chapter 3 Book Test, p. 115. Students have the answers to the questions so that they can check their work. The following are terms that must be understood for the test tomorrow: Biased: Survey result in which samples are chosen or used unfairly to make a point. Convenience Sampling: Using any convenient method to choose a sample for a survey, usually resulting in a biased survey. Fair Wording: Questions asked that are worded in the most neutral way. Graphs: Bar graphs, double bar graphs, and pictographs show specific numbers. Line graphs show changes over time (with time labeled on the horizontal axis), and circle graphs are useful for describing parts of a whole. Mean: The sum of all data divided by the number of data values (the number of numbers added). Measures of Central Tendency: Mean, median, and modes that indicate what is typical in a set of data. Range is not a measure of central tendency. Median: The middle number, or average of the two middle numbers, when ata are arranged in order. Mode: The number(s) that occur most often in a set of data. Outlier: An extreme value in a data set, separated from most of the other values - either very high or very low. Population: The entire group of individuals or items from which a sample is chosen. Random Sampling: Sampling in which each individual or item has an equal chance of being chosen. Random sampling may result in a less biased result. Range: The difference between the greatest and least numbers in a set of data. Representative: A typical example of something, such as a population. Responses to a Survey: Answers to a questionnaire or telephone call designed to get information from a population. This is usually biased; only interested people respond. Sample: A selected part of a large group. Statistician: A statistician collects data, organizes data, finds the measures of central tendency in the data, and analyze data. They do not invent data. Stem-and-Leaf Plots help to visually represent the distribution of data and show how numbers are clustered. The stem represents the numbers above 10; the leaves represent the ones digits. Both need to be read in order to be correct. Finally, THERE WILL BE NO HOMEWORK ASSIGNED OVER THE THANKSGIVING BREAK. ENJOY YOUR FAMILY TIME AND REMEMBER TO TAKE A MOMENT TO BE THANKFUL FOR THE BLESSINGS THAT EACH OF US HAS. Tuesday, November 18, 2008 Lesson 3:8 Analyzing Statistical Results, pp. 108-110, problems 5-16 My goal is to have the chapter test on Friday. Monday, November 17, 2008 Lesson 3:7 Make a Graph, pp. 106-107, problems 5-9 REMEMBER TO USE A RULER TO DRAW YOUR GRAPH. NEATNESS IS ESSENTIAL. Thursday, November 13, 2008 Lesson 3:6 - Sampling Methods pp. 103-105, problems 3-9 Remember: * A Biased Sample is one that does not represent the entire population. (Ex: Standing outside of Whole Foods and asking people their opinion about adding a health food store to the community) * A Random Sample is one in which each person or ting has an equal chance of being chosed. (Ex: picking every 5th person and asking the question) * Random sampling is usually more representative of the entire population. Therefore it is called a representative sample) * Convenience Sampling involves using any convenient method to choose a sample for a survey. The results are usually biased. (ex: Asking parents of students if they would support an increase in taxes for a new middle school) * Responses to a Survey are another form of sampling that is often biased. People with strong opinions are more likely to take the time to mail back a survey form or answer questions on a telephone. Random sampling is important for obtaining measures that accurately describe the population being studied. Wednesday, November 12, 2008 Lesson 3:5 - Understanding Sampling, pp. 100-102, problems 4-14. Remember: A population refers to the entire (all) of a group being studied. A sample is part of a population. It is not always practical or possible to study an entire population, so a sample is taken. Thursday, November 6, 2008 Lesson 3:4 - Choosing the Best Graph, pp. 96-96, problems 1-6 Remember: Bar Graphs and Pictographs show specific numbers Double Bar Graphs compare sets of numbers (comparing one class to another) Line Graphs show changes over time Circle Graphs describe parts of a whole THERE WILL BE NO HOMEWORK ASSIGNED OVER THE LONG WEEKEND. ENJOY!! Wednesday, November 5, 2008 Complete lesson 3:3 (see below). There will be an Accelerated Math exercise tomorrow on Stem-and-Leaf Plots and Mean. Tuesday, November 4, 2008 Math Leson 3:3 Stem-and-Leaf Plots, pp. 94-95, problems 5-14 Monday, November 3, 2008 This website was down for a few days. That was very frustrating, but the students seem to have survived it. Math Lesson 3:2 Data with Outliers, pp. 91-93, Problems 4-13 all, 18-24 evens. Remember than an outlier is a number or numbers in a set of numbers that is far below or above most of the other data. It can affect the median, but usually it has the greatest effect on the mean (Think about my age :) ) Tuesday, October 28, 2008 Accelerated Math corrections Monday, October 27, 2008 Math Corrections: Today students completed an Accelerated Math worksheet on long division with decimals. Tonight's homework will be to make any corrections necessary. Tomorrow we will be starting the next unit: Using Data and Statistics. IF multiplication and division skills are not strong, it is imperative that students work on this at home. Those foundation skills are essential for all of the work this year. Monday, October 20, 2008 Due to parent conferencing, students will be on a block schedule this week What this means is that I saw the class today for over an hour. We worked on pictographs (lesson 2:8) and the Diagnostic Review. Students had time to work on these pages and then check to see if they fully understood the concepts. THE CHAPTER 2 TEST WILL BE GIVEN ON WEDNESDAY. We will have an extended period to work on the test. Thursday, October 16, 2008 Lesson 2:7 SOLVING MULTIPLICATION AND DIVISION EQUATIONS, pp. 68-69, problems #6-26. Remember that you need to "undo" the original operation. 3m = 12 (3 times m equals 12) 3m divided by 3 = 12 divided by 3 m = 4 NEATNESS AND FORMAT COUNTS ON THESE ASSIGNMENTS. EVERYONE GOT A GOOD START ON THIS TODAY. I KNOW YOU WILL DO WELL. THIS IS THE FUN STUFF!!!! Wednesday, October 15, 2008 Lesson 2:3 INTERPRET THE REMAINDER, pp. 56-57, problems 1-5 Also, make corrections on last night's homework. Remember, when dividing by a decimal, move the divisor decimal to the right. Move the dividend decimal the same number of spaces to the right. Pop the dot, and begin dividing. There will be a chapter test coming up soon, but I think we will wait until early next week. Good work, everyone, with a difficult (and time consuming) concept. Tuesday, October 14, 2008 Lesson 2:5 DIVIDING A DECIMAL BY A DECIMAL, pp. 62-63, problems 6-31. NOTE* We did not get to the lesson portion of this assignment today. If students are unable to understand what the process is by reading the examples on p. 62, they can work on it in class tomorrow. What they can do is complete the division process. Then we will discuss decimal placement. Monday, October 13, 2008 Lesson 2:4 DIVIDING BY WHOLE NUMBERS, pp. 55-61, problems #13-50 This is a big assignment, but students were given the entire class period to begin their work and/or ask questions if they were unsure of the division process. Math homework will be corrected tomorrow. Any errors will need to be corrected on the same homework page. Students will complete 10 Accelerated Math problems (5 on multiplying decimals by whole numbers and 5 on dividing whole numbers). The grade on those problems will be entered in the gradebook. Tuesday and Wednesday, October 7-8, 2008 Tonight's homework: Lesson 2:2 MULTIPLYING WHOLE NUMBERS AND DECIMALS, pp. 52-54, problems #6-26. Remember to make sure that the decimal places are correct. I will not be at school on Wednesday due to a family illness. Students will be given an Accelerated Math assignment to be completed in class. There will be no homework over the long weekend. Monday, October 6, 2008 Lesson 2:1 MULTIPLICATION PROPERTIES, pp. 50-51, problems #7-23 If you are not sure about your multiplication tables, now is the time to learn them. Remember that when you are doing tonight's problems, you are looking at the different properties of multiplication to solve the problems. You will need to show your work. Thursday, October 2, 2008 GO THROUGH YOUR MATH BOOK, CHAPTER 1, TO MAKE SURE THAT YOU UNDERSTAND ALL CONCEPTS. COMPLETE THE WORKBOOK PAGES TO PRACTICE YOUR SKILLS MATH TEST - CHAPTER 1 TOMORROW There will be no homework over the weekend. Enjoy! Wednesday, October 1, 2008 Diagnostic Checkpoint, p. 34, problems 1-28. We will go over the answers in class tomorrow and do some review work in preparation for a CHAPTER ONE TEST on Friday. Tuesday, September 30, 2008 Lesson 1:13 USING DATA FROM GRAPHS, pp. 32-33, problems #1-7 Remember that bar graphs are used to show quantities (amounts). They can be vertical or horizontal. A double-bar graph can show two sets of data. WE WILL BE HAVING A CHAPTER TEST ON FRIDAY. Monday, September 29, 2008 Lesson 1:12 SOLVING ADDITION AND SUBTRACTION EQUATIONS, pp. 30-31, problems #6-28. Go back over the examples on p. 30. Remember, if you subtract from one side of the equation, you must subtract from the other side. If you add to one side, add to the other. Always check your answers to see if your solution makes the equation a true statement. WE WILL BE HAVING A CHAPTER TEST ON FRIDAY. Thursday, September 25, 2008 Lesson 1:11 WRITING EXPRESSIONS, pp. 28-29, problems #5-21 REVIEW THE EXAMPLES ON PAGE 28. ALSO, LOOK BACK OVER THE NOTES THAT YOU TOOK IN CLASS TODAY. WE WILL HAVE A CHAPTER TEST NEXT WEEK...PROBABLY WEDNESDAY. Wednesday, September 24, 2008 Lesson 1:10 VARIABLES AND EXPRESSIONS, pp. 26-27, problems #10-34 Tuesday, September 23, 2008 Lesson 1:9 ORDER OF OPERATIONS, pp. 24-25, problems #6-24 Remember PEMDAS (Parentheses, exponents, multiply and divide left to right, add and subtract left to right) WHEN MULTIPLICATION OR DIVISION OCCURS WITH ADDITION OR SUBTRACTION, THE MULTIPLICATION OR DIVISION SHOULD BE PERFORMED FIRST IN ORDER FROM LEFT TO RIGHT. EVERYONE needs to make sure that they have completed the math corrections for the Accelerated Math exercise scored today. Monday, September 22, 2008 1.) There is no math homework tonight. Students completed an Accelerated Math assignment in class. Friday, September 19, 2008 It was very nice meeting all of you who came to Back To School Night last night. For me, it is always nerve-wracking, but you made it a lot easier. Thank you. There is no homework for the weekend. Thursday, September 18, 2008 BACK TO SCHOOL NIGHT Complete Diagnostic Checkpoint, p. 20, problems #1-31 Wednesday, September 17, 2008 Math Lesson 1:8 FIND A PATTERN pp. 22-23, Problems #1-9 Students took a math quiz today. They were aware of it ahead of time. Unfortunately, this website had an error yesterday and would not allow me to enter homework. It's all fixed now. Monday, September 15, 2008 Math Lesson 1:6 ADDING WHOLE NUMBERS AND DECIMALS, pp. 14-16, problems #8-31. *Look at each problem carefully. Do not confuse the comma and the decimal point. September 12, 2008 HOORAY, we have successfully made it through the first full week of school! I am so impressed by all of my students. They are well prepared and very responsible. I will do my best to not assign homework over the weekends. What this means is that students will work hard during the week. Even so, there will be assignments that carry over into the following week now and then. THIS WEEKEND, HOWEVER, THERE IS NO HOMEWORK. Enjoy your two days of relaxation. September 11, 2008 Math Lesson 1:5 ROUNDING WHOLE NUMBERS AND DECIMALS, pp. 12-13, Problems #5-23 Do not forget that your mini-poster is due tomorrow. Read below if you have forgotten the assignment. September 10, 2008 Math Lesson 1:4 ADDITION PROPERTIES pp. 10-11, Problems # 6-23 Students will also need to create a mini-poster that describes the properties of addition, the break-apart strategy, and the compensation strategy. These are all explained on p. 10 of the textbook. Color and creativity count! September 9, 2008 Math Lesson 1:3 EXACT OR ESTIMATED DATA pp. 8-9, Problems # 1-7. REMEMBER to make sure that you have set your math page up correctly and that you show all work where appropriate. EACH NIGHT, YOU ARE RESPONSIBLE FOR CORRECTING ANY ERRORS ON YOUR MATH HOMEWORK. THERE WILL BE A NOTEBOOK CHECK ALONG THE WAY. You are all Great Math-a-maniacs!!! Keep up the good work! September 8,2008 Math Lesson 1:2 COMPARING AND ORDERING DECIMALS, pp. 6-7, problems # 5-24 Make sure that all work is shown and your paper is neat. September 5, 2008 Math Lesson 1:1 Whole Numbers and Decimals, pp. 4-5, #6-29 Make sure that your paper is set up properly, and remember to show all work. Neatness Counts!
