10/7 Unit 2 Closure and Study Guide

1.  Warm-up:  Rewrite each percent as a fraction and decimal:

• 12%
• 132%
• 0.5%

Also, do Closure 3-137 in Chapter 3.

2.  Grade Closure problems

• Put a star for mastery, an "x" for needs improvement

3.  Make Individual Study Guide

• Find your study guide in Google Classroom
• Use the table at the end of the Ch. 2 & 3 Closure section to help you form your study plan
• Turn in your study guide after you have finished creating it.

4.  Mini-groups & Individual study time

Reminder: Individual Test tomorrow, Ch 3 ILP due Friday

10/6 Unit 2 Team Test

1.  Unit 2 Team Test

• Mr. Robinett will grade 1 teammate's paper and the entire team will receive that grade.  Work together.  No one behind, no one ahead.
• Justify your reasoning when necessary.  For example, how do you know you have created the smallest possible number?

2.  Work on Closure problems (due tomorrow) or Chapter 3 ILP (due Friday)

Homework:  Chapter 2 Closure #132, Chapter 3 Closure # 131, 132, 134, 136 due tomorrow

10/5 Simplifying Expressions

1.  Warm-up: Solve the following using mental math (no need to write anything down)

• 3 · ¹/₃ · 4 · 7 · -¹/₅ · 0 · 6 · 3
• 4,556 - 10 - 4,500
• ¹/₆ · (-4) · 3 · 6

2.  Today, we will practice efficiently simplifying expressions.  Efficiently is the key word!  Many times, we can use mental math to break the problem down into small, easy chunks.

Go to Google Classroom and find the document "Efficiently Simplifying Expressions"

You may work independently or with a partner.

3.  Simplifying Expressions quiz

Go to Socrative.com, click Student login, and type in my room code: Robinett

This is a timed quiz. Remember the key word? Efficiency is the key to finishing with time to spare.

Homework:  Chapter 2 Closure #132, Chapter 3 Closure # 131, 132, 134, 136 due Weds.
