Assignment Create a composite figure from a minimum of 3 different shapes and find the area.
	Excellent (N/A)	Good (N/A)	Fair (N/A)	Poor (N/A)
ORGANIZATION	Excellent Final project is well organized, neatly presented in a neat and engaging manner. Viewer can easily follow the flow of information presented.	Good Project is presented in a neat manner, but lacks organization. Writing may not be legible or organized.	Fair Project requires the viewer to study the presentation to find all the pieces of the task. Lacks the necessary neatness.	Poor Project is disorganized, not neat and not legible. The viewer has a hard time trying to make out what the project is about.
REQUIREMENTS Composite Figure created Composite figure decomposed Area of each figure calculated Area of composite figure calculated. Answer in a complete sentence with explain.	Excellent Clearly read and interpreted the requirements of the project. Has everything required on the project.	Good Missing 1 of the requirements needed.<BR> For example; Some labels for figures may be missing.	Fair Missing 2 of the requirements needed.	Poor Missing 3 or more of the requirements needed.
MATH CONTENT	Excellent Math Computations are complete and correct. Data is organized and neat. All work is shown.	Good Math computations have 1-2 mistakes.<BR> Data is organized.<BR> Not all work is shown.	Fair Math computations have 3 - 4 mistakes<BR> Data is not very organized. Not all work is shown.	Poor Math computations have more than 4 mistakes.<BR> Work is poorly organized. No work is shown.
COMPOSITE FIGURE	Excellent Composite figure is made up more than 3 different shapes. The choices are: circles, semi-circles, quarter-circles, triangles, rectangles, squares.	Good Composite figure is made up at least 3 different shapes. The choices are: circles, semi-circles, quarter-circles, triangles, rectangles, squares.	Fair Composite figure is made up of only two different shapes. The choices are: circles, semi-circles, quarter-circles, triangles, rectangles, squares.	Poor The figure is not a composite figure.
FINAL ANSWER AND EXPLAIN	Excellent The problem is answered with a complete sentence and has a full explanation.	Good The problem is answered in a complete sentence but could use more explanation.	Fair The problem is answered, but not in a complete sentence. There is some explanation, but more is needed.	Poor The problem is answered, but not complete and has no explanation.
ASSIGNMENT COMPLETE	Excellent Student created more than 1 composite figure, found the area of the figure, and showed all of their work.	Good Student created at least 1 composite figure, found the area of the figure, but didn't show all of their work.	Fair Student created at least 1 composite figure, didn't find all of the areas, and didn't show their work.	Poor Student did not complete the assignment correctly and is missing many parts.
