Grading Scales and Rubric Conversions

 

Rubrics are often used for Math, Written Expression and projects.

Here is a conversion from rubric points to percents: 4=100% 3.5=94% 3=88% 2.5=82% 2=73% 1.5=64% 1=55% 0.5=28%

One example of a Math Rubric:

4. -

• Strategy: An appropriate strategy is used effectively.
• Organization: The response is highly organized and well documented.
• Communication: Responses to all parts of the prompt are effective and appropriate.
• Solution: A correct solution is presented.
• Mathematics: Efficient, accurate use of mathematics is evident throughout.

3. - A three is basically the same items; however, they are scaled down. For example, many of the same things are done, but not effectively.

2. - A two would consist of a partially correct response.

1. - A one is a strategy that is attempted or unclear.

     0.  - A zero is no attempt or off of the point.

Example of a Cooperative Learning project rubric:
                       4                                  3                                        2                 1

Organization	Extremely well organized; logical format that was easy to follow; flowed smoothly from one idea to another and cleverly conveyed; the organization enhanced the effectiveness of the project	Presented in a thoughtful manner; there were signs of organization and most transitions were easy to follow, but at times ideas were unclear	(2).Somewhat organized; ideas were not presented coherently and transitions were not always smooth, which at times distracted the audience	(1)Choppy and confusing; format was difficult to follow; transitions of ideas were abrupt and seriously distracted the audience
Content Accuracy	Completely accurate; all facts were precise and explicit	Mostly accurate; a few inconsistencies or errors in information	Somewhat accurate; more than a few inconsistencies or errors in information	Completely inaccurate; the facts in this project were misleading to the audience
Research	Went above and beyond to research information; solicited material in addition to what was provided; brought in personal ideas and information to enhance project; and utilized more than eight types of resources to make project effective	Did a very good job of researching; utilized materials provided to their full potential; solicited more than six types of research to enhance project; at times took the initiative to find information outside of school	Used the material provided in an acceptable manner, but did not consult any additional resources	Did not utilize resources effectively; did little or no fact gathering on the topic
Creativity	Was extremely clever and presented with originality; a unique approach that truly enhanced the project	Was clever at times; thoughtfully and uniquely presented	Added a few original touches to enhance the project but did not incorporate it throughout	Little creative energy used during this project; was bland, predictable, and lacked "zip"
Presentation Mechanics	Was engaging, provocative, and captured the interest of the audience and maintained this throughout the entire presentation; great variety of visual aids and multimedia; visual aids were colorful and clear	Was well done and interesting to the audience; was presented in a unique manner and was very well organized; some use of visual aids	Was at times interesting and was presented clearly and precisely; was clever at times and was organized in a logical manner; limited variety of visual aids and visual aids were not colorful or clear	Was not organized effectively; was not easy to follow and did not keep the audience interested; no use of visual aids
