Learning Target: Students will be able to solve quadratic inequalities graphically and apply these skills in real world applications. Formative Assessment: Students will follow along, answer questions during lesson, and discuss/compare ideas and solutions with peers. Students will successfully present in a group about a real world application of quadratic inequalities. Mathematical Practice: CCSS.MATH.PRACTICE.MPS Use appropriate too ls strategically. CCSS.MATH.PRACTICE.MP6 Attend to precision. Content Standard: CCSS.MATH.CONTENT.HSA.REI.D. I 0: Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line). Activitiesffasks

Beginning of class routines: (5 min) Review of solving quadratic inequalities algebraically

Ask for the steps to solving a quadratic inequality. What is another way we can solve a quadratic ineq uality?

Students will go over the steps to solving a quadratic inequality algebraically and think of how else they could solve quadratic inequalities and discuss.

Activityff ask 1: (20min) Solving a quadratic inequality graphically

Another way we can solve these inequalities is to graph them. Like the other way, it usually takes 4 steps to solve a quadratic inequality graph ically. I. Get f(x) on one side and zero on the other Graph y = f(x) 2. 3. Find the zeros on the graph 4. Identify the interval(s) of the graph that satisfy the inequality Go over example I together then have students do example 2 on their own or in pairs before discussing as class. Split into groups to work examples 3 and 4. Have someone from each group sketch their graph and write their solution on the board. Discuss similarities/differences.

Students will follow along, take notes, answer questions, work examples, and d iscuss work and solutions.

Transition: (2 min) Questions

What questions do you have over solving quadratic inequalities graphically? Which method of solving do you prefer?

Students will ask questions if they have any and discuss which method they prefer and why.

here are several ways to apply what you have learned about solving inequalities in real life. We are going to divide into 5 groups, with each grou learning a real world application of quadratic inequalities. Once everyone has reviewed their assigned a lication, the groups will then " teach" it to the rest of the class.

Students will work in groups watching their assigned video on real world applications while taking notes and discussing within groups. Groups wi ll then lead a whole class discussion over each application video. Groups will point out and discuss the pros/cons of eac reso urce.

What questions do you have over solving quadratic inequalities? We saw five different real world applications, give some more examples of how you personally could apply this in your life.

Students will ask any remaining questions over the lesson. Wrap up discussion of possible personal use of solving quadratic inequalities.
