S-Sit and organize materials for the lesson… Get your journal, Springboard book and a sharpened pencil.

E-Examine and follow teacher’s directions… On your next blank page, write today’s date at the top. Title this page ~ Lesson 7-1 Modeling and Writing 2-step Inequalities

T-Take the challenge! Write the CQ in journal below the title: Challenge Question: What is the difference between an equation and

an inequality?

Warm-up: Write and solve the equation modeled (on the right). Then, graph the solution on a number line.

I prefer the algebraic method rather than guess and check, because guess and check involves much more checking and time.

We have practiced graphing solutions to

equations (or equalities).

Here are 4 graphs of inequalities. Look at the graphs… when do you

color in the circle and when do you leave it open?

15.99x + 9.99 ≤ 100.00

15.99x ≤ 90.01 - 9.99 -9.99

15.99 15.99X ≤ 5.629

So would that be 5 or 6 DVDs?

Writing an inequality is an equation

without an equal sign (use one of the

inequality symbols instead)

Look at your equation from #3 to help you write the inequality

What do I do?

1. Look back at your Frayer Model now that you have completed Activity 7-1. Is there anything you want to add? If so, do it now.

2. Answer the CQ in your journal. We’ll discuss answers in a few minutes.

Wrap-up

W- Write homework assignment in planner (complete Lesson 7-1 Practice #s 14-15 on pg. 69, due on Tuesday 10/28)R- Return materials and organize supplies

A-Assess how well you worked in a group or individually

Did I/we maintain operating standards?Did I/we work toward learning goals?Did I/we complete tasks?

P- Praise one another for high quality work: Tickets for a “P” performance overall
