Understanding of geometric principles (volume, area, unit rate, and relationships)	Does not use geometric terms, or uses them incorrectly. Presentation of processes used to determine unit rate is missing or completely incorrect.	Correct use of geometric terms is inconsistent. Explanation of geometric process begins to show understanding, but is incomplete or only partially correct.	Generally uses geometric terms correctly. Explanation of geometric process shows basic understanding of the relationships between unit rate, area, and volume.	Uses geometric terms correctly. Thoroughly demonstrates understanding of how volume and surface area determine the unit rate.
Using geometric formulas	Generally uses incorrect formula, or does not use formulas at all. Enters incorrect information into formulas. Consistently fails to generate accurate solutions.	Occasionally uses correct formulas, and sometimes enters correct information into those formulas. Frequently fails to generate accurate solutions.	Generally chooses appropriate formulas for different tasks. Enters correct numbers into formulas and calculates correct solutions with reasonable consistency.	Thoroughly demonstrates understanding of which geometric formulas to use, when to use them, and why. Enters numbers into formulas and calculates solutions correctly.
Creating prototype	Prototype is neither a cylinder nor a prism. Little or no obvious effort to make package appealing to consumers. Work is sloppy or incomplete.	Prototype is either of an inappropriate shape or shows little effort to appeal to consumers. Work is sloppy or incomplete.	Prototype is a cylinder or prism. Demonstrates some effort to appeal to consumers. Work is generally neat.	Prototype is a cylinder or a prism. Demonstrates extensive effort to make package appealing to consumers. Work is tidy and shows attention to detail.
Persuasive writing skills	Does not state position. Provides no appropriate evidence. Lacks organization; content is confusing or difficult to follow.	May fail to state position clearly. Lacks sufficient evidence, or evidence isn't consistently appropriate. Organization may not be clear or easy to follow.	Provides a reasonable argument with more than one appropriate pieces of evidence. Explains value of evidence. Clearly organized and easy to follow.	Provides compelling evidence to support thesis and convincingly explains the value of that evidence. Clearly organized and easy to follow.
Business letter formatting	Does not use any business letter formatting.	Some attempt to use correct formatting, but some elements are missing, incomplete, or spaced incorrectly.	Formatting generally correct; may lack an element and/or have minor errors in spacing.	Contains all elements of a business letter, organized and spaced correctly.
Writing mechanics	Mechanical errors interfere substantially with the reader's understanding .	Mechanical errors distract reader from the content.	A few minor mechanical errors do not interfere with the reader's experience.	Few if any mechanical errors.
