Proposal demonstrates a thorough understanding of how shape and dimensions affect surface area and volume.
|
Proposal reflects an appropriate and systematic approach for solving the problem. It includes at least one alternative design. The rationale for rejecting this design is mathematically valid. The justification matches the proposed design.
Proposal demonstrates a thorough understanding of what surface area and volume measure.
|
Executes algorithms completely and correctly: Container dimensions fall within the range of established specifications. Computations match the dimensions in the diagram. Appropriate formulas are used.
All elements of the diagram are clearly labeled and explained. The diagram(s) and
model are drawn to scale. Extra care and attention were given to the product's
appearance. |

Proposal suggests a general understanding of the relationship between shape and dimension
with respect to surface area and volume. |
Proposal reflects an appropriate strategy for solving the problem. An alternative design is discussed.
Proposal demonstrates a substantial understanding of what surface area and volume measure.
|
Executes algorithms completely; computations are generally correct butmay contain minor errors: Correct formulas and algorithms are applied. Container dimensions fall within the established specifications. Computations match diagram and/or specifications.
The diagram is clearly labeled. The diagram is drawn to scale. The model matches the
diagram. |
2 |
Proposal identifies a distinction between surface area and volume, but shows only
limited understanding of the relationship between shape and dimension with respect to
surface area and volume.
|
Proposal appears to reflect an appropriate strategy but application of strategy is unclear, or inappropriate strategy is applied logically and consistently.
Proposal suggests an incomplete understanding of the relationship between surface
area and volume. |
Contains major computational errors: Incorrect formulas may be applied. Container dimensions may not fall within the established specifications. Computations may not match diagram and/or specifications.
The diagram may be unclear. Elements are missing or unexplained. The diagram may not
be to scale. The model may not match the diagram. |
1 |
Proposal fails to identify surface area and/or volume, or places too much emphasis on
unimportant elements. |
Proposal gives minimal evidence of the solution process.
Proposal shows serious misunderstanding with respect to the concepts of surface area and
volume. |
Contains major computational errors: Algorithms are executed haphazardly or incompletely. Dimensions do not appear to satisfy the given specifications. Computations do not relate to design or design is missing altogether. The diagram is unclear or non-existents. The model does not match the
diagram or is nonexistent. |
