Grade scale 0 (F) to 5 (A). Scale points 2 and 4 are not explicitly defined. A score of 2 (C) would be assigned to work that exceeded criteria for a score of  1, but did not meet criteria for a score of 3. Similarly, a score of 4 (B+) would be assigned to work that exceeded criteria for a score of 3, but did not meet criteria for a score of 5.

 I: Conceptual Understanding
Conceptual Understanding includes the ability to interpret the problem and select appropriate information to apply a strategy for solution. Evidence is communicated through making connections between the problem situation, relevant information, appropriate physical and mathematical concepts, and logical/reasonable responses.

5. (grade = A) Full Conceptual Understanding:

3 (grade= B-) Partial Conceptual Understanding:

1 (Grade = D )Lack of Conceptual Understanding:
  II: Procedural Knowledge
 Procedural Knowledge deals with the student's ability to demonstrate appropriate use of concepts. Evidence includes the verifying and justifying of a procedure using concrete models, or the modifying of procedures to deal with factors inherent in the problem.

5 (A) Full Use of Appropriate Procedures:

3 (B-) Partial Use of Appropriate Procedures:

 1 Lacks Use of Appropriate Procedures
 III: Problem Solving Skills and Strategies
Problem Solving requires the use of many skills, often in certain combinations, before the problem is solved. Students demonstrate problem solving strategies with clearly focused, good reasoning that leads to a successful resolution of the problem.

 5 (A) Evidence of Thorough/Insightful Use of Skills/Strategies:
 3 Evidence of Routine or Partial Use of Skills/Strategies:
 1 Limited Evidence of Skills/Strategies:
IV: Communication
In assessing the student's ability to communicate, particular attention should be paid to both the meanings he/she attaches to the concepts and procedures and also to his/her fluency in explaining, understanding, and evaluating the ideas expressed.

5 (A) Clear, Complete Communication:

 3 (B-) Partial or Incomplete Communication:
1 (D) Limited or Lack of Communication:
