## Bard Does a Lesson Plan – If You Are Still Teaching, You Should Use This. I asked Google’s Bard to “Prepare a lesson plan to teach the quadratic equations at the high school level.” Below is what I got back. My conclusion is that if I were still teaching, I would always ask for Bard’s plan before I made my own. I might not use Bard’s plan, but I would look to it for ideas. I would certainly share the Additional Resources links with my students. If you are still teaching, why aren’t you doing this? This is probably more detailed than your real lesson plans and will impress your principal.

Subject: Algebra II

Time: 50 minutes

### Learning Objectives

Students will be able to identify and define quadratic equations.
Students will be able to graph quadratic equations.
Students will be able to solve quadratic equations using factoring, completing the square, and the quadratic formula.
Students will be able to apply quadratic equations to real-world problems.

### Materials

Whiteboard or projector
Markers or pens
Graph paper
Calculators (optional)
Worksheets (optional)

### Introduction (5 minutes)

Elicit responses from students and provide a brief overview of the topic.
Explain that quadratic equations are polynomial equations of the second degree, meaning they have a highest power of 2.

### Identifying Quadratic Equations (10 minutes)

Display a variety of equations, some quadratic and some not.
Ask students to identify which equations are quadratic and explain their reasoning.
Provide examples of quadratic equations in various forms, including standard form, factored form, and vertex form.

### Graphing Quadratic Equations (10 minutes)

Review the concept of graphing equations in general.
Introduce the concept of the axis of symmetry for quadratic equations.
Demonstrate how to graph quadratic equations using vertex form.
Allow students to practice graphing quadratic equations on their own or in pairs.

### Solving Quadratic Equations (20 minutes)

Introduce three methods for solving quadratic equations: factoring, completing the square, and the quadratic formula.
Explain each method step by step, using examples to illustrate the process.
Provide students with practice problems to solve using each method.

### Real-World Applications (5 minutes)

Discuss real-world situations where quadratic equations can be used to model problems.
Provide examples of such problems, such as calculating the height of an object launched into the air or determining the profit or loss of a business venture.
Encourage students to think of their own examples of real-world applications of quadratic equations.

### Closure (5 minutes)

Summarize the key points of the lesson.
Review the different methods for solving quadratic equations.
Encourage students to ask any remaining questions.

### Assessment

Observe students’ participation in class discussions and activities.
Collect and review worksheets or homework assignments.
Administer a quiz or test to assess students’ understanding of the material.

### Differentiation

For students who need more support, provide additional practice problems with worked-out solutions.
For students who are ready for more challenging material, introduce the concept of complex numbers and solving quadratic equations with complex roots.
