## Description

Please see attachment for creating an lesson plan. The topic for the lesson plan is 9th grade algebra " A1.A.SSE.B.3b, Complete the square in a quadratic expression in the form Ax2 + Bx + C to reveal the maximum of the function it defines." See attached checklist and lesson plan example for how the lesson plan has to be written. Also use information on Standard A1.A.SSE.A.2 (Major Work of the Grade), which is also attached to help with the topic. It is on page 11 and 12 the standard that needs to be used.

A1.A.SSE.B.3b Complete the square in a quadratic expression in the form Ax2 + Bx + C to reveal the maximum of the function it defines

Standards

Literacy Standard(s):

• Students should be able to not only identify if they need to factor a quadratic or complete the square with a quadratic, but also provide a justification

based on the context of the problem to explain why they chose a specific form for the quadratic expression.

• Additionally, beyond simply finding the zeros of an expression and determining their meaning within a realworld context, students should develop an

understanding of how many zeros are generated from quadratic expressions and what the number of zeros can mean in the context of a realworld

situation.

Practice Standard(s):

Reasoning with Equations and Inequalities

Seeing Structure in quadratic expressions

Students should be working with quadratic expressions embedded in realworld situations and let the context of the situation drive the structure of

how the expression is written in order to answer a question embedded in the situation.

Learning

Segment

Student understanding of factoring should draw on connecting how and why a quadratic expression and a factored form of the same expression are

equivalent.

Central FocusStudents need to conceptually understand how factoring works and why factoring works.

Prior Knowledge/Skills –

The students have previously interacted with several algebraic expressions that are going to serve as a foundation for this lesson such as seeing structure

in expression and quantities. Some concepts might be new but overall the idea is similar, and they are all interconnected; Expressions, arithmetic with

Polynomials & Rational, etc.

Learning

Context

Current Lesson –

The student will learn how to complete the square in a quadratic expression to reveal the maximum of the function it defines.

Subsequent Lessons –

The student will learn new methods on how to complete the square in in other algebraic expressions, not just the quadratic expression

Lesson Title Quadratic expression.

Learning Objective (s)

Factor a quadratic expression to reveal the zeros of the function it defines.

Identify equivalent forms of quadratic expressions.

Determine the maximum or minimum value of a function defined by a quadratic expression in the form Ax2 + Bx + C by completing the square.

Generate an equivalent form of the exponential expression and identify the properties of exponents used to generate the equivalent expression, for

an exponential expression embedded in a realworld context.
