Scaled drawing
	Excellent 4 pts	Good 3 pts	Fair 2 pts	Incomplete 1 pts
Knowledge	Excellent Shows complete understanding of scale factor/Accurately determines scale factor of figure.	Good Show moderate understanding of scale factor/Determines scale factor/minor computational errors	Fair Shows familiarity with Scale/ Determines scale factor/major computational errors	Incomplete Show no understanding of scale factor/Does not determine scale factor
Strategies	Excellent Shows clear evidence of a complete and systematic solution process Selects efficient strategy for determining scale factor	Good Selects appropriate strategies for determining scale factor Shows evidence of systematic solution	Fair Selects a strategy, may be unable to analyze and determine scale factor Little evidence of a systematic solution process	Incomplete Selects an inappropriate strategy determine scale factor No evidence of a systematic solution process
Communication	Excellent Uses appropriate notation involving scale factor and ratio Provides written description of solution	Good Uses appropriate notation, may lack completeness Provides written description of solution	Fair Limited use of appropriate ratio and scale factor notation, may be incorrect Provides some written description of solution, may be incomplete or unclear	Incomplete Does not use notation, or applies it inappropriately Does not provide an acceptable written description of solution
