## Reflection: Vertical Alignment Reasoning About Inequality Solution Sets - Section 2: Intro to New Material

If we have a snowy school year, and I need to make up some instructional days, this lesson is one that I can cut from the unit.  I include this lesson, though, to set students up for success for the rest of the unit.

There is a lot of practice we need to do, in terms of correctly reading inequalities.  More so, we need practice in naming the inequality symbols.  My students generally come to me prepared to read 6 < 19 as 'six is less than 19.'  However, when asked to name the symbol that would allow us to compare 7 and 18, students generally don't come to me ready to say the less than symbols.

Frequent responses:  "the mouth is open to the 18," or "the alligator is eating the 18!"  Often, students are drawing teeth in their inequality symbols (and some have even made 'nom nom nom' sounds :) )

This lesson is really all about making sure students have the academic vocabulary to talk about inequalities.

# Reasoning About Inequality Solution Sets

Unit 9: Inequalities
Lesson 1 of 7

## Big Idea: An inequality is an algebraic statement that a quantity is greater than, less than, or equal to another quantity. A solution to an inequality is any value that makes the inequality true.
