|
| Apprentice |
- A partially correct strategy is chosen, or a correct strategy for only solving part of the task is chosen.
- Evidence of drawing on some relevant previous knowledge is present, showing some relevant engagement in the task.
|
- Arguments are made with some mathematical basis.
- Some correct reasoning or justification for reasoning is present with trial and error, or unsystematic trying of several cases.
|
- Some awareness of audience or purpose is communicated, and may take place in the form of paraphrasing of the task.
- Some communication of an approach is evident through verbal/written accounts and explanations, use of diagrams or objects, writing, and using mathematical symbols.
- Some formal math language is used, and examples are provided to communicate ideas.
|
- Some attempt to relate the task to other subjects or to own interests and experiences is made.
|
- An attempt is made to construct mathematical representations to record and communicate problem solving.
|
| Practitioner |
- A correct strategy is chosen based on the mathematical situation in the task.
- Planning or monitoring of strategy is evident.
- Evidence of solidifying prior knowledge and applying it to the problem-solving situation is present.
Note: The practitioner must achieve a correct answer. |
- Arguments are constructed with adequate mathematical basis.
- A systematic approach and/or justification of correct reasoning is present. This may lead to:
- Clarification of the task.
- Exploration of mathematical phenomenon.
- Noting patterns, structures and regularities.
|
- A sense of audience or purpose is communicated.
- Communication of an approach is evident through a methodical, organized, coherent, sequenced, and labeled response.
- Formal math language is used throughout the solution to share and clarify ideas.
|
- Mathematical connections or observations are recognized.
|
- Appropriate and accurate mathematical representations are constructed and refined to solve problems or portray solutions.
|
| Expert |
- An efficient strategy is chosen and progress toward a solution is evaluated.
- Adjustments in strategy, if necessary, are made along the way, and/or alternative strategies are considered.
- Evidence of analyzing the situation in mathematical terms, and extending prior knowledge is present.
Note: The expert must achieve a correct answer. |
- Deductive arguments are used to justify decisions and may result in more formal proofs.
- Evidence is used to justify and support decisions made and conclusions reached. This may lead to:
- Testing and accepting or rejecting of a hypothesis or conjecture.
- Explanation of phenomenon.
- Generalizing and extending the solution to other cases.
|
- A sense of audience and purpose is communicated.
- Communication at the practitioner level is achieved, and communication of arguments is supported by mathematical properties used.
- Precise math language and symbolic notation are used to consolidate math thinking and to communicate ideas.
|
- Mathematical connections or observations are used to extend the solution.
|
- Abstract or symbolic mathematical representations are constructed to analyze relationships, extend thinking, and clarify or interpret phenomenon.
