12/17 Number Sense Quiz; Lessons 4.2.1/4.2.2 Tidy-up

1.  Number Sense Quiz

2.  Tidy up Lessons 4.2.1 and 4.2.2

• Focus questions:
• How can you use a table to decide if a relationship is proportional?
• How can you use a graph to decide if a relationship is proportional?
• 4 graphs side by side with their tables underneath
• 3 relationships are proportional, 1 is not.  Can you find the one that is not proportional?  What makes it different from the rest?  Explain what is different about the graph.  Explain what is different about the table.
• Math Notes:  Proportions in tables and graphs

3.  Now you try:  Problems 37 through 39 in teams (page 204)

No Homework tonight!

12/16 Prepare for Number Sense Quiz

1.  Grab a Number Sense practice packet from the guest teacher.  This will help you prepare for the Number Sense quiz tomorrow.

You may work quietly with a partner at your table group, but you may not move around the classroom.

Try at least 5 problems on every page!  Do not spend the entire period working on one page.  Practice each of the skills multiple times

Use a calculator only to check your answers!


2.  If you finish the practice packet early, grab a computer and continue working on your Ch. 5 ILP

Homework:  Continue practicing for the quiz tomorrow

12/15 Lesson 4.2.2

1.  Warm-up:  Examine the graphs from Lesson 4.2.1  Copy the T-chart (on side whiteboard) in your notebook and discuss with your team:  What similarities and differences do you note between the two graphs?

2.  Lesson 4.2.2 Proportional Relationships with Tables and Graphs

• Objective:  I will be able to recognize a proportional relationship by looking at either a table or a graph
• Problem 34: Graph Penny Tower data by hand
• Problem 35: Graph using Desmos.  Answer questions on the half-sheet as a team.  Be prepared to share out your team's answers.
• Whole class discussion:
• How can you use a table to decide whether a relationship is proportional?
• How can you use a graph to decide whether a relationship is proportional?

3.  Exit ticket- Did you meet the objective?

• Problems 37 and 38

Homework:  4.2.2 R/P (answers in GC) 

12/14 Lesson 4.2.1 Recognizing Proportional Relationships

1.  Warm-up:  Number Sense problems (on side whiteboard)

2.  Announcements:

• Chapter 4 ILP, due last Monday, is in the grade book.  Too many zeros and incomplete.
• Chapter 5 ILP due Friday 1/8.  Paper copies available
• Number Sense quiz on Thursday.  It will be very similar to our Chapter 3 Test

3.  Lesson 4.2.1 Recognizing Proportional Relationships

• Review from Friday:  Gustavo's College Fund
• Problems 22 through 24 as team/whole class discussion
• Problem 25 in teams.  Copy the ratio table into your notebook.

Homework:  Lesson 4.2.1 R/P (answers in GC)

Finish Lesson 4.1.2, Start Lesson 4.2.1 Recognizing Proportional Relationships

1.  Warm-up:

Investigate each pair of figures.  Are the pair of figures similar?  How do you know?
