Unit 3 – Introduction of Concepts

2. Warm Up 1) How many letters are in your middle name?
OBJECTIVE: SWBAT understand the concept of a statistical question, and develop a method to collect data to answer a statistical question.
1) How many letters are in your middle name?
2) Ask 5 class mates how many letters are in their middle names, and write them down.
3) Based on the results from question 2, try to guess how many letters the next person has in their middle name. Explain why you guessed this!
(5 min) 0 – 5
In-Class Notes
1) This question should take less than 5 seconds and it only asked to emphasize the difference between this question and the next two questions.
2) Notes
Pay attention to the way students write down the middle names
Make attempts to try and create visual displays, or some sort of order, rather than just a list.
3) First introduction to center
Students are already familiar with the concept of average, but some might just take a guess that looks like it is near the other numbers.
Try to see if anyone picks the median or the mode as well.
There is no correct answer here, let the students have fun explaining why they picked their answer.
Preparation Notes
The first two problems should be quicker, and the third problem provides some time for students to think more carefully about the mathematics that is going on when they guess. Whether they realize it or not, their brains are already beginning to apply some of the rules of probability and statistics.
Agenda

3. Agenda: 1) Warm Up 2) Launch – What is a statistical question?
OBJECTIVE: SWBAT understand the concept of a statistical question, and develop a method to collect data to answer a statistical question.
1) Warm Up
2) Launch – What is a statistical question?
3) Explore – Group activity: Collecting Data
4) Summary – Introduce a Line Plot and Bar Graph
5) Practice – Interactive worksheet
(1 min) 5 – 6
In-Class Notes
Briefly review today’s objective and agenda, pointing out that they will do some exploring in partners, have an opportunity to do some independent practice interleaved with teacher help, and then be asked to show what they’ve learned on an exit ticket.
Preparation Notes
The structure of today’s lesson was designed to provide a relatively small amount of exploration, combined with a summary that guides them to constructing the formula for area of parallelograms. The interleaving practice then gives them the opportunity to practice applying the formula, as well as the key underlying skill of identifying the height in a parallelogram (not confusing it with the slant height). It is designed to be interleaving rather than totally independent because research shows that to be more effective than completely independent work.
6) Assessment – Exit Ticket

4. Launch A Vocabulary What is the definition of a statistical question?
A statistical question is a question where the answer can change depending on who it is asked to, and when it is asked.
This kind of change is called variability.
(2 min) 6 – 8
In-Class Notes:
Preview that the launch has 3 main sections (Launch A, B, & C) so students do not get lost in the launch. See Preparation Notes for explanation.
Teacher asks question and elicits a few student responses.
Click to show formal definition.
Have the students copy down the definitions as necessary in a notebook, or wherever they generally copy down definitions.
Preparation Notes:
There are three main ideas in the launch that students need to know to become familiar with a statistical question:
A. What is a statistical question?
B. How can we determine whether a question is a statistical question?
C. What does it mean when we say we are collecting data for a statistical question?
Agenda

5. (Wait time: 30 seconds for each question)
Launch B
(Wait time: 30 seconds for each question)
Can you determine whether the following questions are statistical question or not?
1. What did everyone in the class eat for breakfast today?
Statistical Question! …Why?
2. What did YOU eat for breakfast today?
Not a statistical Question… Why?
3. How many people in the class ate breakfast today?
Not a statistical Question…Why?
4. Who was the first president of the U.S.A.?
(2 min) 8 – 10
In-Class Notes
Give students 30 seconds each for the questions.
Accommodation: Hand out a piece of paper for students that would like more time to look at the questions.
Use calling sticks to have students share their answers
Remind students they are answering whether it is a statistical question or not; they are not answering the questions themselves!
Make sure students realize a statistical question is independent of whether the question has anything to do with numbers.
Preparation Notes
Have the students explain WHY they chose the answer they did. This will help some students who were confused by the definition of statistical question really understand the meaning. This will help them focus more on how to collect data later on, rather than getting stuck in the technical jargon.
Not a statistical Question… Why?
5. How many points does Lebron James have in each game?
Statistical Question! … Why?
Agenda

6. Can you come up with your own

Agenda

7. Launch B Let’s go back to our warm up question:
How many letters are in each students middle name?
Answers:
(<1 minute) 12 – 13
In-Class Notes
Go around the room quickly, asking each student to read off their answer.
Don’t pay attention to organization, just type in the answer as you hear them.
Tell the students to copy these down as you do, because they will need them very soon. If they don’t end up copying them all down, you can display the data again as they are working in partners.
Type in the answers to the box that is provided. When they are doing their exploration you can return to this slide to show the data again.
Preparation Notes
The idea is to show how messy the answer of a statistical question can be when just the raw answer is observed.
“I have no idea what all these numbers are saying! If only I could organize them better…”
Agenda

8. Launch C
The answers for our statistical questions have a special name. They are called our data.
Data: The counts, measurements, or opinions that are collected to answer a statistical question.
Notice how some of the numbers in our data show up more than once. This has a special name as well:
Frequency: The number of times an answer shows up in the data.
(1 min)
In-Class Notes
Make sure the students copy down these vocabulary words again.
Check to make sure some students aren’t confusing frequency with mode.
Preparation
Be prepared to give some examples of data.

Data
Agenda

10. Explore – Student Share Out
Part 2 - (3 Min)
Students share out work.
(3 min)
In-Class Notes
The summary should begin with students sharing their methods for decomposing and recomposing shapes.
Display the key questions if possible while students share (using document camera, overhead projector, or another normal routine you have for sharing student work).
If multiple methods were used during the Explore time, be sure to have students share in the order that leaves the main objective method for last.
Preparation Notes
It is possible to continue the summary without a student share-out. However, the thinking behind having students share their methods is that it builds in incentive for students to work for interesting solutions and ideas during the Explore time (today and in the future), it provides students a chance to take pride in their work and to practice presentation skills, and it helps with student engagement to have students listen to other students instead of the teacher’s voice when possible.
Classwork Questions
Agenda

11. Explore – Complete top half of worksheet Part 3 - (5 Min)
Fill out the top half of your worksheet.
(5 min)
In-Class Notes
Have students present their work
For the second question:
Pay attention to how they organize their data.
Some will put the data in a list of increasing or decreasing order, and some will put their data into groups (For example, Four people have five letters, 3 people have six letters…)
For the third question:
Have students project what they’ve done with a document camera if possible, if not, have them describe what they’ve done since it might be too time consuming to reproduce it on the board.
For the fourth question:
Pick a couple groups to explain their model, it will take too much time to have everyone go.
Have the students explain how their model is easy to understand, and ask them how they represented the different answers clearly.
Preparation Notes
Not every student will have a great method of representing the data. This is OK! The summary section that is next will give them two great tools they can use in the future in the line plot and bar graph.
Also, some students might have other useful visuals, such as a pie chart, which is fine. Let them know, although their method is good, it is useful to be aware of other methods as well.
