Stage 1 –Desired Results
Where are we going?
NY State Standards:
See Curriculum Developer Lessons
CCSS:
A-SSE: Interperet the structure of expressions
Understand solving equations as a process of reasoning and explain
the reasoning
1. Explain each step in solving a simple equation as following from the
equality of numbers asserted at the previous step, starting from the
assumption that the original equation has a solution. Construct a
viable argument to justify a solution method
Solve equations and inequalities in one variable
3. Solve linear equations and inequalities in one variable, including
equations with coefficients represented by letters.
Standards for Mathematical Practice:
 Make sense of problems and persevere in solving them.
 Reason abstractly and quantitatively.
 Construct viable arguments and critique the reasoning of others.
 Model with mathematics.
 Use appropriate tools strategically.
 Attend to precision.
 Look for and make use of structure.
 Look for and express regularity in repeated reasoning.
Learning Outcomes/Goals:
 Student will distinguish between an algebraic expression and equation
 Student will translate verbal phrases to algebraic expressions and equations
 Students will solve equations in one variable including fractional expressions
 Students will solve word problems requiring writing and solving equations
 Students will solve literal equations for a given variable
Enduring Understandings:
We will understand…
An equation represents two quantities that
are equal and can be used as a tool to find
an unknown value
Essential Questions:
Why do we use equations to solve
problems?
Why do you perform operations on both
sides of an equation?
How is thinking algebraically different
from thinking arithmetically?
Algebraic expressions and equations
How do the properties contribute to
generalize relationships from specific cases algebraic understanding?
