1.  Warm-up:  If you have not done so already, convert your tennis court measurements into inches

Announcement: Survey data gathered by the end of the day tomorrow!


2.  Essential Question:  How long is the baseline of the tennis court?

• Input your data into the form in Google Classroom
• Examine the class data and record any initial observations you make
• Are there any measures that look very different from the others?  These extreme values are called outliers.
• Mini-lesson: How to construct a histogram
• Order data from least to greatest
• Decide on a bin width
• Put boxes around the data, in other words, organize the bins
• Graph the frequencies using a bar-graph method
• Create a histogram of the ruler data using the same bin width as the tape measure

What do you notice when you compare the histograms side by side?

Based on this data, what do you think is the actual length of the tennis court?

Homework:  Construct a box plot of ONE of the sets of data (ruler or tape measure).  You will need to find the range, median, first quartile, and third quartile.

a)  What is the range of this set of data?
b)  What is the median of this set of data?

2.  Lesson 8.1.1 Measurement Precision

• Essential Question:  What is the length of the tennis court?
• We will use 2 different tools to try to answer this question: a 12-inch ruler, and a measuring tape.
• Discuss these questions in your team:
• Will you get the same measurement with each tool?
• Why might the measures be different?  Should they be the same?
• Which tool do you think will give the more precise measurement, that is the one that is closer to the true measurement of the tennis court?
• Partner up (within your teams)
• Field trip to the tennis courts- bring notebook and pencil for recording measurements

Everyone can earn back points on their test!  You are eligible to earn back half of your points by completing the rework.  You do not have to rework any problem that you scored 100% on.

To earn back points, you must rework the problem AND complete the Ninja Practice problems.  All problems must be solved correctly to earn the points.

There are 6 stations in the room, 1 station for each of the problems on the test.

Each station is being taught by a student-mentor who demonstrated mastery on the test.  This student-mentor will explain their process, and help with the rework.

After 5 minutes we will switch so that everybody (not including student-mentors) will travel to every station.

There are other experts in the room!  After the student-mentor explains their solution feel free to explain yours as well.  But, your first job is to listen to the student-mentor without interrupting (just like you would with a teacher).

The goal of this activity is to help each other understand how to solve the test problems and Ninja Practice problems.  Everyone is a teacher, and everyone is a student.  Let's work together so that we can all be successful!

Use a 5-D Process Resource Page to guide your thinking

2.  Lesson 6.2.4 Using Algebra in the 5-D Process

• Objective:  I will write algebraic equations to solve real-world problems
• Problems 94 and 95 using Red Light, Green Light
• Clearly define what the variable x represents
• Search for the "key."  The key is the quantity all others depend on.  Make the key your variable
• It may be helpful to do one or two trials (guess and check) before solving the equation
• Check that your final answer makes sense

Homework:  Lesson 6.2.4 R/P all

3/11 Lesson 6.2.3 Review/Preview

1.  Warm-up:  SBAC Practice



2.  Lesson 6.2.3 Review/Preview (page 349)

• Complete Problems 81-90 (skip #84)
• You may work with your Algebra Tiles partner, but you both will turn in your own work
• When you finish, correct your work using the answer key in Google Classroom
• No corrections = automatic 20% deduction
• Re-work problems that were done incorrectly
• Turn in your work to the folder for class participation points

3/10 Lesson 6.2.3 Solving Equations and Recording Work

1.  Field Trip to the LOFT for Open House

2.  Lesson 6.2.3 Solving Equations and Recording Work (page 346)

• Objective:  I will record my process so anyone reading my work will understand my steps
• Problems 71 through 74 as Red Light, Green Light
• There is a Resource page for Problems 71 and 73, but you will still need to read the problems in your book
• Dojo Challenge:  Problem 75

No Homework tonight!

3/9 Finish Lesson 6.2.2 and Order of Operations check-in

1.  Warm-up:  

Missy was solving the equation 2(x + 4) = 3x + 2

She found a solution of x = -2.  Check Missy's solution and give her feedback.

Hint:  Review your notes from yesterday and/or use the sample problem on the side whiteboard.


2.  Finish Lesson 6.2.2 (page 344)

• Problem 64 as Red Light, Green Light
• Check your answer after finishing each sub-problem
• Document the process (build it, record it, simplify it, record it, check your solution)

2.  Order of Operations Check-in (green worksheet)

• This was the Checkpoint problem from Chapter 5, but we never got to it in class.
• At this point, it is expected that you have mastered the 4 basic operations and exponents without using a calculator
• This is an assessment (non-graded) to see your progress.
• This is a completely INDIVIDUAL assignment.  No collaboration, please

Homework:  Lesson 6.2.2 R/P #67-69
