Learning target: I can analyze and solve quadratic equations by completing the square.
Before completing the square, you should teach completing the square for expression of the form x^2 + bx first. I have a free version of said lesson. Additionally, you should also teach solving quadratic equations using square roots (I've a paid version for this lesson) before completing the square. In this lesson, I included a brief lesson/practice on completing the square for expression of the form x^2 + bx and solving quadratic equations using square roots.
Teacher will model the example(s). Students will then use think-pair-share to answer the group-work problems. Students will present their work to the class.
Contact me if you need the workout solutions.
- Do now
- Teacher modeling (when a = 1 and when a is ≠ to 1)
- Group-work (when a = 1 and when a is ≠ to 1)
Differentiation: you can have students do think pair share # 1; students will choose
any two of the letters to complete. You can have students do think pair share # 4;
they will choose between a or b. Also, you can have students do think pair share #
9; students will choose between a or b and then choose between c or d.
