1 5.8 Quadratic Inequalities Learning Objective: To write, solve and graph a quadratic inequality in two variables.Warm-up (IN)Graph the inequalities.15 Minutes - The first part of the warm-up will be a review of the last lesson, and the 2nd is an algebra review to prepare the students for the algebra that will be done in the notes and homework with isosceles triangles.20 minutes – Check answers to even problems from HW, then to over any questions.
2 EX 1 – Graph the solution to: Learning Objective: To write, solve and graph a quadratic inequality in two variables..NotesEX 1 – Graph the solution to:41 minutes for notesEssential Questions:What is the isosceles triangle theorem and it’s converse?
3 Learning Objective: To write, solve and graph a quadratic inequality in two variables. Essential Questions:How can you use the Isosceles triangle theorem to write a paragraph proof?
4 Out – Explain how to test whether the correct area has been shaded in the graph of an inequality. Summary – Inequalities are…HW – p335 #42-57(mult of 3), 61, 66,67,78,805 minutes for Summary and closing questions.I will have the students do the Out as a ticket out.
