40, 49, 68, 104, 84, 72, 95, 145, 38, 94, 85, 1000, 68, 94, 102

2.  Lesson 8.1.2 Comparing Distributions

• Objective:  I will compare distributions using different measures of central tendency (mean, median) depending on the circumstances.
• A brief introduction to golf
• Problem #19 using Desmos tool
• Discussion:  When to use "mean" vs. "median"
• Definition: Inter-quartile Range (IQR)
• Problems #20-22 in teams

No homework this weekend!

2/4 Lesson 8.1.1 Measurement Precision

1.  Warm-up:  Log-on to your computer, and enter your individual data from yesterday into the Google Form.

2.  Lesson 8.1.1 Measurement Precision

• Objective:  I will analyze the precision of different measuring tools using box plots and histograms
• Let the analysis begin!  Discuss the questions in Problem 4 with your team. 
• Make a histogram (bin width 5) and box plot for each set of data.  Refer to Problem 5 for instructions.  You will have 4 graphs total
• Class Discussion of data

3.  Closure:  Walk and Talk (Problem #7)

Homework:  Lesson 8.1.1 R/P #13-18

2/3 Lesson 8.1.1 Measurement Precision

1.  Warm-up:  In your "CLASSWORK" section, copy the data table on the side whiteboard

2.  Lesson 8.1.1 Measurement Precision

• Objective:  I will analyze the precision of different measuring tools using box plots and histograms
• Problem #1 as team discussion
• Field Trip!
• Everybody inputs their own data in a Google Form (in Google Classroom)
• Let the analysis begin (Problems 4 and 5)

Homework:  Lesson 8.1.1 R/P #8-10, 12 only!

2/2 Percent Test

After you have finished the test, turn it face down on your desk and:

• Work on tonight's homework
• Try a logic puzzle from this website (click the link)
• Or a Calcudoku puzzle, also known as Ken-Ken (click the link)
• Read silently

Homework:  Lesson 7.2.2 R/P #117 Checkpoint Problem (Histograms and Box Plots)  USE GRAPH PAPER

2/1 Chapter 7 Closure + Percent Test Prep

1.  Chapter 7 Closure activity

• You will need your notebook, a pencil, and a calculator for this activity
• There are 6 problems arranged in the classroom
• Problems A & B are on tables 1-3
• Problems C & D are on tables 4-6
• Problems E & F are on tables 7-9
• You will pair up with another student and take turns solving a problem.
• When it is your turn, you must explain how you would solve the problem.  Your partner will take notes.  Your job is to use math evidence to convince your partner that your solution is correct.
• If your partner agrees with your answer, switch roles.
• If your partner disagrees, he/she must use math evidence to explain why.  Make sure you reach consensus before moving on to the next problem.
• Move to another set of problems.  Find a new partner for the next set of problems
• KEEP A WHISPER VOICE FOR THIS ACTIVITY

2.  Percent Test Prep

• Grab a worksheet from Table 5.  I suggest you work on this individually in preparation for tomorrow's test.
