TOPIC: Inequalities

GOAL: 

• Write word sentences as inequalities. 

•  Determine whether a value is a solution of an inequality. 

• Graph the solutions of inequalities.

Essential Question: How do I use algebraic equations to analyze or solve problems? 

STANDARDS: 

• CCSS.MATH.CONTENT.7.EE.B.4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

• CCSS.MATH.CONTENT.7.EE.B.4.A Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?

What does the equal sign indicate in an equation? 

Can you choose any number from the numberline to be a solution of the inequality?
