MATH LESSON PLAN
DATE 27 March 2012
SUBJECT: Algebra I
TOPIC: Factoring any factorable Trinomial
GRADE: 7
TIME/PERIOD: 50 minutes
OBJECTIVES:
SWBAT - identify greatest common factors of terms.
SWBAT – factor any factorable trinomial with integral coefficients.
SWBAT – associate vocabulary words with mathematical concepts.
STATE STANDARDS (COMMON CORE STANDARDS)
Core Standard #4 – Polynomials. Multiply polynomials, factor polynomials, and divide a polynomial by a monomial.
Core Standard #5 – Quadratic Equations and Functions. Solve quadratic equations by graphing, factoring, and using the quadratic formula. Graph quadratic
functions and understand the relationship between its zeros and the x-intercepts of its graph. Solve problems that can be modeled using quadratic equations.
ELL STANDARD
ESL Standard 7.2 – Language minority students will listen, speak, read, and write to negotiate and express meaning.
TIME
TEACHER ACTIVITY
5
Anticipatory set-the hook
min
The students already know two different methods of factoring
trinomials. Give two problems on the board, one straightforward
and easily factored, and one with very large, composite
coefficients. Students will realize that they need a new method
or this problem will take forever to solve.
STUDENT ACTIVITY
MATERIALS
Paper, pencil
With a partner, try to solve the problems. The first should be
solved easily, nobody should get the second.
15
min
Instruction
LECTURE: Show kids the written instructions of the factor by
grouping method and have them write the steps down.
Begin simplifying some expressions on the board using the
aforementioned steps and constantly looking back to the steps
and making sure the difference between each step is clear.

min
Practice
Guided: Read two problems out loud to the students, one of
medium difficulty and one very difficult, and have the students
correctly write them simplify them. When everyone is finished
come back and work through the problems together.

Assessment
Formative: Thumbs up or down
Notebook, pencil
Writing down the steps of the process.
Taking notes and following along with problems on board that
show clear connections between steps.
Translating spoken English into mathematical symbols then
simplifying relevant expressions
Worksheet
Respond when asked whether or not they feel prepared to do
their homework after the lesson.

Closure:
Ask the kids to look for times they have to use math over the
weekend.

Start thinking about when they have to do math in their daily
lives.
Rationale for this lesson:
Factoring trinomials is an extremely important skill for any sort of applied physics and engineering. Factoring provides a simple way to find roots of a polynomial
in algebra. Other examples of useful factoring include division of polynomials in algebra I and II and finding points of inflection and concavity of graphs in
calculus. Direct instruction is best suited for this lesson because seventh grade students will not be able to produce this advanced method without being shown.
