Product Description
Included in this zip folder is 10 PDF files. 4 are for instruction, 3 are assignments and 3 are student printables of information about the discriminant.

PDF Instruction file #1 is a 39 page file. The emphasis is on the discriminant of quadratic equations, not graphs(yet). There are example problems to be used as formative assessment. There are example problems to view as exemplars.

PDF Instruction file #2 is the same as file #1. It is saved on 7 pages, 6 slides per page.

PDF Instruction file #3 is a 34 page file. The emphasis is on the discriminant and its relationship to a graph, specifically the x axis. There are examples to be worked as whole class formative assessment. There is also some examples to be viewd as exemplars.

PDF Instruction file #4 is the same as file #3. It is saved on 6 pages, 6 slides per page.

PDF Student printable #1 is on 1 page for easy printing. The emphasis is on equations. These 4 outcomes are summarized:
1. 1 Real, Rational Solution
2. 2 Real, Rational Solutions
3. 2 Real, Irrational Solutions
4. 2 Imaginary Solutions

PDF Student printable #2 is on 1 page for easy printing. The emphasis is on how a quadratic function hits the x axis, if at all and the discriminant.

PDF Student Printable #3 is on 1 page for easy printing. The emphasis is how the lead coefficient and the discriminant can be analyzed to determine much about a quadratic function.

PDF Assignment file #1 is on 1 page for easy printing. It is a 27 question assignment. The student is asked to distinguish between rational, irrational and imaginary numbers. The student is also asked to find the discriminant of a quadratic equation. Finally, the student is asked to determine the type(s) of solutions of a quadratic equation from:
1. 1 Real, Rational Solution
2. 2 Real, Rational Solutions
3. 2 Real, Irrational Solutions
4. 2 Imaginary Solutions

PDF Assignment file #2 is on 1 page for easy printing. It is a 20 question multiple choice assignment. The student must pick the best graph given information about the discriminant and the lead coefficient.

PDF Assignment file #3 is on 1 page for easy printing. It is a 24 question assignment. The student is asked to find the discriminant of a quadratic function, The student is also given 8 graphs and to choose the best one based on a given quadratic function. The student should use the discriminant and the leads coefficient to find the best graph.
