10/14 Lesson 2.2.4 Multiplication as Repeated Addition

1.  Warm-up:

You may want to use this eTool to help you solve this problem.

2.  Game Time!  "Win-a-row"


3.  Lesson 2.2.4 Multiplication as Repeated Addition

• Objective:  I will rewrite addition problems using multiplication
• How can we use multiplication to rewrite 7 + 7 + 7 + 7?  How about 2 + 2 + 2 + 2 + 2?
• Problems 71 through 73 with your team
• Focus on strategies for modeling multiplication (number line and integer tiles)

4.  Exit ticket:  Draw a visual model using either a number line or integer tiles

       a)    7(-2)

       b)    4(3) + 2

Homework:  Lesson 2.2.4 R/P due Friday

10/13 Lesson 2.2.3 Addition of Integers and Rational Numbers

1.  Warm-up:  Of the 3 building blocks we learned yesterday, (zero pair, addition with number line, absolute value) choose one that you feel comfortable explaining.  Prepare a short explanation to share with your classmates.

Announcement:  Ch. 1 retest is tomorrow @ lunch or after school

2.  Lesson 2.2.3  Addition of Integers and Rational Numbers

• Objective:  I will develop more strategies for solving addition problems (with negative numbers).
• Problem 56 with your team
• Game time!  Win-a-row
• Mini-lesson:  Integer addition using integer tiles
• Problem 58 with your team
• Class discussion:  Considering what you know, what strategy would you use to solve -200 + 14?
• Use a similar strategy for rational number addition in Problem 60

Homework: Lesson 2.2.3 R/P (answers in GC)

10/12 Lesson 2.2.2 Zero Pairs and Absolute Value

1.  Warm-up:  No computers today. Resource Managers: grab 2 textbooks for your team to share.  Turn to page 88

2.  Lesson 2.2.2 Zero Pairs and Absolute Value

• Objectives:
• I will simplify expressions efficiently using zero pairs
• I will simplify expressions involving Absolute Value

Finished with the problem early?  Don't wait around doing nothing.  Try Challenge problems #46 and 47

Do: Problem 43.  Focus word: "Zero pair."  How can we describe Cecil's movement with relation to a zero pair?

Mini-lesson:  Number line addition

Do: Problem 44

Mini-lesson:  Absolute Value

Do: Problem 45

Announcements:  

• Chapter 1 Re-test on Weds (at lunch or after school)
• Minecraft tournament applications due tonight.  See blog post from Friday

Homework:  Lesson 2.2.2 R/P (answers in GC)

10/9 Lesson 2.2.2 Adding Integers and Rational Numbers

1.  Warm-up:  Stick-Math Puzzle on side whiteboard

2.  Minecraft Tournament:

• Application form

3.  Lesson 2.2.2 Adding Integers and Rational Numbers

• Key concepts:
• Zero Pairs
• Absolute Value
• For rational numbers, think about money
• Objective:  I will be able to add integers and rational numbers
• Participation Quiz: Problems 42 and 43
• Encourage the use of team roles
• Finish at least the first 3 parts of problem 42
• Timer is set for 15 minutes

4. Closure:

• What is a zero pair?  What does a zero pair do to Cecil's movements?  Why are zero pairs important?
• Participation Quiz debrief

Homework:  Lesson 2.2.2 R/P due on Tuesday

10/8 Lesson 2.2.1 Composing Integers

1.  Warm-up:  Imagine that your partner was absent yesterday.  Explain to them (by writing in your warm-up section) how to quickly:

• Convert 0.82 to a fraction
• Convert 0.456 to a fraction
• Convert 0.828282...(repeating) to a fraction

2.  Lesson 2.2.1 Composing Integers

• Tightrope walking video.
• Objective:  I will be able to compose numbers in multiple ways
• Do: Problems 31 through 34
• Challenge: Problem 35

3.  Closure:  Refer back to problem 34.  Does the order that Cecil moves in matter?
