1. Take out last night’s homework assignment for me to come by and grade. Take out your “Opener” hand out.

2. You will have about 10 minutes to work out the Opener problems. Work together to make the best use of your time.

3. Once you are done, turn in the “Opener” hand out in the tray under the projector. The answers will appear for you to check how well you did.

4. Next, write down the “Section & Title” and “SWBAT” into your notebooks in the next 5 minutes.

Instructions:

Opener

Use the resources on the internet and each other to help you relearn the concept.

Use whiteboards.Work together.

Rewrite each of the following into slope intercept form.

Section & Title

Write down the date, Section #, Title and Learning Objective(s) into your notebook.

SWBAT graph a system of 2 or more inequalities and find the intersection of regions, if they exist.

Please take a couple of minutes to check your answers to the even numbered problems in the previous assignment. Correct the ones you got wrong and write the total number of correct over the total number in the top right hand corner.

Be prepared to either ask a question or answer one.

… Now let’s start the new lesson by reviewing our objectives …… Underline the words that have been omitted …

Be prepared to answer!

SWBAT graph a __?__ of 2 or more inequalities and find the __?__ of __?__, if they exist.

Key ConceptsLOOK LISTEN

What do you remember from Algebra 1 about graphing linear inequalities?

• Take 30 seconds to think about it.• Look in your text book.• Brainstorm with your table group.• Get ready to share out with the class.

Write down what you want into “Key Concepts” as you Look & Listen.

Next we need to understand what to do:

1. Write into slope intercept form.2. Gather information before graphing:• Slope as a fraction• Y – Intercept• Dotted or Solid? (D or S)• Above or Below? (A or B)

3. Graph each inequality.4. Describe the solution set – where the two regions

intersect or “mix it up.”

Now let’s try together.Use whiteboards.
