## Objective

Students will be able to solve radical equations.

#### Big Idea

Multiple representations and problem solving are the key features of this radical equation lesson.

## Warm Up and Homework Review

10 minutes

I include Warm ups with a Rubric as part of my daily routine. My goal is to allow students to work on Math Practice 3 each day. Grouping students into homogeneous pairs provides an opportunity for appropriately differentiated math conversations.  This lesson’s Warm Up- Polynomial Review Day 2, asks students to determine which of three radical equations has an extraneous solution.

I also use this time to correct and record the previous day's Homework.

## Radical Equations

37 minutes

This lesson is a Guided Practice lesson meant to build both student skill with radical equations and student understanding of extraneous solutions.

I begin with a problem similar to the ones from the previous lesson.  We then extend to new types of radical equations.  I have carefully selected to problems and order to build student skill and understanding.  I add problems as necessary.  Please watch my Video Narrative on maximizing student thinking during this lesson.

Please see the PowerPoint for detailed presentation notes.

## Exit Ticket

3 minutes

I use an exit ticket each day as a quick formative assessment to judge the success of the lesson.

Today's Exit Ticket asks students to solve a radical equation.

## Homework

This assignment ensures that students are capable of independently solving the radical equations seen in the lesson. The final problem asks students to create a radical equation with an extraneous solution. This gives them an opportunity to use what they know about the structure of a radical equation (Math Practice 7).

This assignment was created with Kuta Software which is an excellent resource for a mathematics teacher.
