Radical Equations Day 2
Lesson 6 of 8
Objective: Students will be able to solve radical equations.
Warm Up and Homework Review
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.
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.
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.
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.
