11/20 Lessons 2.1.8 and 2.1.9 Solving Equations

1.  Warm-up:  Stick puzzle on side whiteboard

2.  Lessons 2.1.8 and 2.1.9

• Objective:  I will use "legal moves" to simplify and solve algebraic equations
• Problem 75 (page 78) and Problem 83 (page 81) in teams.
• Always check that your answer is correct by substituting your solution for "x" back into the original equation
• Hint: Some equations might have no solution.  What do these types of equations have in common?

No Homework over the break! Have a safe and relaxing holiday!

11/19 Lesson 6.1.4 Solving, writing and graphing inequalities

1.  Warm-up:  Yesterday, we came across some scenarios in which the 3 "legal moves" couldn't be applied, yet the expressions weren't fully simplified.

Two such scenarios are posted on the side whiteboard.  For each scenario, create a legal move that would simplify the expressions into a single variable on one side, and a collection of unit squares on the other.

2.  Lesson 6.1.4 Solving, writing and graphing inequalities.

• Objective:  I will solve, write and graph inequalities related to real-world problems
• Team Check marks!  Problems 36 through 40

Homework:  Lesson 6.1.4 (7th grade) R/P

11/18 Lesson 6.1.3 Solving and Graphing Inequalities

1.  Warm-up:

a)  Which expression is larger, Mat A or Mat B?

b)  Find at least 4 values of x that would make Mat A larger.

2.  Lesson 6.1.3 Solving and Graphing Inequalities

• Objective:  I will solve and graph inequalities using Expression Comparison Mats
• Problem 26 as class discussion + Mini-lesson
• Build-Simplify-Graph cooperative learning worksheet

Homework:  Lesson 6.1.3 R/P

11/17 Unit 3 Project Gallery Walk

1.  Warm-up:  On Problem #1 of yesterday's Sage and Scribe activity, we were left with the following expressions:

Left expression                      Right expression
        x                              1

Which is greater?  What additional information do you need to know?

What if the Left expression is 5y and the Right expression is 4y?


2.  Unit 3 Project Gallery Walk

• Half the class sets up, the other half walks around the room
• Respect people's projects.  Do not touch until given permission.  
• Ask questions.  If you are displaying your project, be ready with answers
• Leave constructive feedback
• A positive comment followed by a suggestion

3.  Unit 3 Project Turn-in

• Paper turn-in vs. Digital turn-in

4.  Finish Sage and Scribe activity

Homework:  Lesson 2.1.7 R/P (answers in GC)
