1. WARM UP 1. Define in your own words the words mean/average. 2. Define in your own words what median means

2. TURN IN YOUR HOMEWORK AND SIGNED CLASS EXPECTATIONS Make sure your name is on both sheets

3. OBJECTIVE Students can interpret the meaning of a dot plot and histogram graph Language objective-students can explain the what shape, center and range mean.

4. MATH1UNIT 2 INVESTIGATION 1

5. GROUP WORK VS. COLLABORATION Group work 1 person answers the rest copy No one discusses, everyone just works by themselves Students are together but not a team Collaboration Everyone is working together Everyone is on the same problem at the same time Discussion is happening If a question arises the student with the question asks the group first before they come to me Everyone is helping everyone complete the task

6. STRUCTURED COLLABORATION Rally Round Robin Each person will have a turn to answer a given question or problem The activity can be timed or untimed Each person will have a chance to answer the same question or a different question, and if they need help they can ask their elbow partner for a tip (NOT THE ANSWER) we are all responsible for our learning and giving the answer to a student does not help them to learn Once everyone has answered you can either go around again, or if it is timed I will have a timer and know when we have all participated THE KEY to a structured activity is that everyone participates at least once in the rotation.

7. COLLABORATION Getting into groups should take less than 30 seconds So lets practice…

8. LET’S GET TO KNOW OUR TEAMMATES Each person will have 45 seconds to answer the following questions 1. What did you do all summer 2. What was your favorite part of the summer (besides sleep) 3. What are you most looking forward to for the year? (aside from graduating) 4. Do you own any pets? What are they?

9. COLLABORATION IN INVESTIGATIONS Recall that when we are investigating a topic we are collaborating One person will read the paragraph the rest of the group will follow along Everyone is working on the same problem at the same time We are all writing down the answers At the end of the investigation today, I will collect at random 1 paper and score the whole group based on that one paper, so everyone needs to be on task and completing the work

10. TEAM INVESTIGATION 1 Get into your teams and turn to page 76. Read starting at investigation 1. Use the note guide to answer the questions in the book. Your team will be responsible for defining the following words. RangeSkewed to the right Shape Skewed to the left Dot Plot Histogram

11. TEAM DEFINITIONS (CHECKPOINT 1) Range-the difference between the maximum and the minimum number Shape- the outline of the total graph Skewed left- when the tail of the distribution stretches to the smaller values or to the left Skewed Right – When the tail of the distribution stretches to the right or the larger values

12. TEAM DEFINITIONS (CHECKPOINT 2) Dot Plot Histogram Frequency

13. CALCULATIONS How to calculate Range How to calculate Mean of a distribution

14. HOMEWORK Page 83. Check Your Understanding (CYU) part a, b (only the histogram, and part c.
