Verifying and applying Identities
	Poor 1 pts	Fair 2 pts	Good 3 pts	Excellent 4 pts
Mathematical Concepts 50 % Must include: Derivation of Pythagorean Identities, proof of sum and difference, derivation of double and half for the sine, cosine and tangent. Must be able to apply identities in verifications, solving equations, calculating exact values.	Poor Explanation shows very limited understanding of the underlying concepts needed to solve the problem(s) OR is not written	Fair Explanation shows some understanding of the mathematical concepts needed to solve the problem(s).	Good Explanation shows substantial understanding of the mathematical concepts used to solve the problem(s).	Excellent Explanation shows complete understanding of the mathematical concepts used to solve the problem(s).
Mathematical Reasoning 10 % Reasoning is annotated in your work either in writing or in oral commentary.	Poor Little evidence of mathematical reasoning.	Fair Some evidence of mathematical reasoning.	Good Uses effective mathematical reasoning	Excellent Uses complex and refined mathematical reasoning.
Strategy/Procedures 20 % You may chose any means you'd like to communicate your understanding of the fundamental objectives of the unit. Videos, quizlets, identity games, Google site, Google Docs of any type...	Poor Rarely uses an effective strategy to solve problems.	Fair Sometimes uses an effective strategy to solve problems, but does not do it consistently.	Good Typically, uses an effective strategy to solve the problem(s).	Excellent Typically, uses an efficient and effective strategy to solve the problem(s).
Mathematical Errors 10 %	Poor More than 75% of the steps and solutions have mathematical error	Fair Most (75-84%) of the steps and solutions have no mathematical errors.	Good Almost all (85-89%) of the steps and solutions have no mathematical errors.	Excellent 90-100% of the steps and solutions have no mathematical errors.
Neatness and Organization 10 %	Poor The work appears sloppy and unorganized. It is hard to know what information goes together. OR was not included.	Fair The work is presented in an organized fashion but may be hard to read at times.	Good The work is presented in a neat and organized fashion that is usually easy to read.	Excellent The work is presented in a neat, clear, organized fashion that is easy to read.
