Explanation shows complete understanding of the mathematical concepts used to solve the problem.

Explanation shows substantial understanding of the mathematical concepts used to solve the problem.

Explanation shows some understanding of the mathematical concepts needed to solve the problem(s).

Explanation shows very limited understanding of the underlying concepts needed to solve the problem(s) OR is not described in the presentation.

Mathematical Terminology and Notation

Correct terminology and notation are always used, making it easy to understand what was done.

Correct terminology and notation are usually used, making it fairly easy to understand what was done.

Correct terminology and notation are used, but it is sometimes not easy to understand what was done.

There is little use, or a lot of inappropriate use, of terminology and notation.

Mathematical Errors

80100% of the steps and solutions have no mathematical errors.

Almost all (6079%) of the steps and solutions have no mathematical errors.

Most (5059%) of the steps and solutions have no mathematical errors.
