Grade 5AGL Expressions and Equations

6.EE.8

Full Standard

Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.

 

Learning Targets (I can)

  • Explain what an inequality is.
  • Represent an inequality with a number line.
  • Write inequalities.
  • Use inequalities to represent real-world situations.
  • Recognize that inequalities can have infinite solutions.

 
About the Math

Many real-world situations are represented by inequalities. Students write inequalities to represent real world and mathematical situations. Students use the number line to represent inequalities from various contextual and mathematical situations. A number line diagram is drawn with an open circle when an inequality contains a < or > symbol to show solutions that are less than or greater than the number but not equal to the number. The circle is shaded when the number is to be included. Students recognize that possible values can include fractions and decimals, which are represented on the number line by shading. Shading is extended through the arrow on a number line to show that an inequality has an infinite number of solutions. Essential vocabulary for this standard includes: greater than, >, less than, <, greater than or equal to, ≥, less than or equal to, ≤, and inequality.
