1. How do you predict the winner of an election before the election takes place?

2. In this lesson you will learn how to collect data about a population by identifying a sample of the population.

3. Let’s Review How many texts do middle school students send in one day? Statistical questions are used to gather data about a population.

4. Core Lesson That could take a long time…

5. Core Lesson By surveying a sample of the group, you can make a generalization about the entire group.

6. The population is the entire group being studied. A sample is part of the population being surveyed.

7. For example: Predict the winner of the upcoming presidential election Adults walking to work American votersPopulation Sample

8. Another example: Tracking migration pattern of birds Tagged birds A bird speciesPopulation Sample

9. In this lesson you have learned how to collect data about a population by identifying a sample of the population.

10. Guided Practice Identify the population and sample in the following survey: To gauge students’ preference for a new school mascot, the Student Council President surveys her soccer team. Population Sample

11. Extension Activities Answer the following questions. 1.You are buying ice cream for a party at your school, in which 700 students will attend. How would you use sampling to make a generalization about students’ preferred ice cream flavors? 2.Why not survey all 700 students? 3.Describe the sample you would survey, and explain why you chose that sample.

12. Investigate the texting habits of middle school students in the United States by conducting a survey in class today. 1.Write the survey question, survey the students in your class, and record the data. 2.Calculate the average number of texts sent. 3.Use the data from your sample to make a generalization about the population. Make sure to identify the population and sample. Extension Activities

13. Describe a sample of each of the following populations. 1) Stop lights in the United States 2) American politicians 3) Professional athletes 4) Hospital employees Extension Activities

14. Quick Quiz Identify the population and the sample: 1. A telephone survey is given to 2,000 randomly selected families in order to predict the average amount of money American families spend on groceries each week. 2. To determine the number of students who carry backpacks in school, Tina collects data on the first 100 students who enter the building.

15. Let’s Review How many texts do middle school students send in one day? Mean Median Mode Range Interquartile Range Mean Absolute Deviation Statistical measures are then used to analyze that data.

16. Lesson Slides Rubric Use this rubric to ensure your lesson plan is great!

17. Math Rubric Criteria for SuccessThings to avoid Storyline or Arc of the Lesson  There is a clear arc to the lesson. One slide leads naturally to the next so that there is a flow and a building of meaning  All the components of the lesson are there but they seem disconnected, as if the author wrote each without thinking about how they fit into the whole. Hook Slide  The teacher poses a simple question that illicits the response, “yeah, I do wonder how that works…”  The question is short  A relevant example is included when it is short and further pulls the learner in  The question mirrors what the student will learn, then need to do later in the guided practice  The question seems formulaic, inauthentic, or overly “school- ish” (message: you have to learn this because you’re in school rather than, this is genuinely interesting)  The hook is overly-complicated and potentially confusing  The question does not parallel the guided practice questions Objective Slide  The objective follows the form (you will learn X by doing Y)  Is concise and follows the form provided in the examples  Does not follow the form  Is overly vague in describing either the X or the Y  Is too long  Is written for teachers but not students Let’s Review  Reminds the student of how this lesson fits with other lessons (the lesson, however, should still be able to stand on its own)  Reminds the student of important vocabulary  Is as concise as possible  Uses visuals whenever possible  Is either too detailed or not detailed enough in connecting the lesson to other lessons  Leaves out important touch points  Makes the lesson overly dependent on the other lessons (student will be confused or feel like they’ve made a mistake, if they watch this lesson alone)

18. Common Mistake  Points out a common mistake that students make  Concisely explains the thought process that leads to that mistake  Isn’t actually a mistake students make (too simple)  Is confusing or vague Modeling a Way of Looking at It  Clearly models a way to look at the standard  Uses visuals as often as possible to show how the way of looking works  Is in “think aloud” format. The teacher is opening up his/her thought process to the student  Takes advantage of every opportunity to explain why the math works the way it works  Engages the learner by asking questions along the way to build suspense  Uses an an example to show the way in action  Explains how this way of looking at it shows why the common mistake (see above) is a mistake  Focuses on the algorhythm (or trick) instead of on showing a way of looking at the math  Fails to use visuals to show a way  Fails to explain his/her thinking along the way. The teacher effortlessly runs through the steps as if it’s all obvious and easy  Does not ask any questions along the way to pull the learner in  Misses opportunities to explain the why behind the math  Fails to explain why this way of looking at the math addresses the common mistake Objective Review  Reviews the objective in a way which conveys, “we’ve come full cicle and now you see this objective with new eyes.”  Serves as a “let’s pull this all together” moment that helps organize the lesson in the learner’s mind  Creates abrupt feeling between the lesson and the reviewing (subtext: “we’re done with this lesson, let’s quickly bring it to a close.”) Guided Practice  Is at the same difficulty level modeled in the lesson  Is connected to the initial hook question  Seem unrelated to the hook question  Is at a different difficulty level than that modeled in the lesson

19. Extension Activity Suggestions  Includes a suggestion for a struggling student who needs more opportunities for practice  Includes a suggestion for students who seem to get it but need more practice  Includes a suggestion for students who get it and are ready to be challenged further  Suggestions should clearly build from the approach in the core lesson  Does not include differentiation  Does not thoughtfully connect or flow from the lesson  Does not clearly build from the approach in the core lesson  Does not give a range of activities Aesthetics  The slides use the correct colors (blue, green, red) in the correct sequence.  The slides use the correct fonts  The slides use handwriting and the handwriting appears as written in the right places  The slides only use the headers/titles provided  The slides use the provided visuals or include visuals created by the author or LearnZillion  The slides use animation, highlighting, and circling to scaffold the learning, keeping the eye focused on what the teacher is introducing/explaining  The slides clean and uncluttered. The visuals and text do not exceed the maximum amount (see tutorial for example of maximum)  The slides use other colors or vary the order of the colors  The slides add new headers/titles that aren’t part of the template  The slides use clip art  The slides are cluttered  Animation is distracting and feels more like sizzle than part of the steak
