Standards-based Lesson Plan (High Achievers)
Standards/Elements: Expressions and Equations (Unit Two)
Solve real life and mathematical problems using numerical and algebraic expressions and equations.
Use properties and operations to generate equivalent expressions.
Essential Question(s):
 What is a variable?
 What does it meant to evaluate an expression?
 What is the difference between an expression and an equation?
 How does the order of operations help us to simplify expressions?
 How do I simplify algebraic expressions?
 How can we use variables to solve equations?
 How do we solve word problems using variables?
 What properties do I need to understand in order to simplify and
evaluate algebraic expressions and solve equations?
Enduring Understanding




Variables can be used to represent numbers in any type of math
problem.
The differences between an expression and equation.
You can write equations for all types of problems involving real
numbers.
Some equations may have more than one solution and
inequalities definitely have more than one value that makes the
statement true.

to group by level of mastery to
complete this activity:
Quiz over writing, evaluating,
and simplifying expressions
using the Distributive
Property.
Review/Activity Day covering
Algebraic expressions – iPad
carts for a Kahoot review.
Review HW: take 3 examples
of writing and translating
expressions from students.
Give one more to do.
Finish Cloze notes?
Work
Session
(About
30
minutes)
Slides with pairs of problems
that illustrate the properties
we cover, e.g. (2 + 3) + 4 =
9
and 2 + (3 + 4) = 9 What’s
the same, what’s different for
each pair? Ask students if
they can see a rule.
Introduction to properties
PowerPoint. Students will
take notes on the different
properties (commutative,
associative, and distributive).
The main focus will be on the
distributive property.
Cornell/Cloze notes.
Students will be able to
recognize properties and
usefulness in simplifying
expressions through an
Identifying Properties
worksheet (work with
partner).
Use data from Monday TOTD
and observation to group by
level of mastery to work on
this lesson:
Textbook – Lesson 6.2 pp
303-306.
Simplifying expressions using
properties, especially
distributive property
Students will work in class on
Problem #1 (1-4) except for
#4d. Check with partner for
correctness.
Textbook – Lesson 6.2
Rewrite expressions in an
equivalent form using the
distributive property
Students will complete Problem
#1 question 5 (a-d). Check
with partner for correctness.
Goal: 80% or higher
