Chapter 2: Solving one-step equations and inequalities
Stage 1 – Desired Results

AERO.7.NS.1d-Apply properties of operations as strategies to add and
subtract rational numbers.

AERO.8.EE.7b-Using the distributive property and collecting like terms.

AERO.6.EE.5 Understand solving an equation or inequality as process of
answering a question. Use substitution to determine whether a given number
in a specified set makes an equation or inequality true.

AERO.8.EE.7-Solve linear equations in one variable.

AERO.HSA.CED.1-Create equations and inequalities in one variable and use
them to solve problems.

AERO7.EE.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.
Enduring Understanding:
Students will understand that
 Even though with the
variables, the expressions
are still following the same
properties as a numerical
expression.
Essential Questions:
 What does “x” mean?
 What is the difference of an
inequality and an equation?
Why we graph an inequality
but not an equation?
 How many solutions in an
inequality?
 How can we make calculate
easier?
Knowledge:
Students will know
 The properties of addition
and multiplication and how
to use them.
 The distributive Property
 Different types of equations
and how to check the
Skills:
Students will be able to
 Use the Distributive
Property.
 Write and solve equations.
 Write, solve, and graph
inequalities.

answers.
 How to use the four
different operations to
solve one-step equation
and inequality.
 Use numbers properties to
do mental math.
