The Colorful Side of Slope Graphing Linear Equations: Stained Glass In this project, students must graph 12 linear equations on a coordinate plane in order to create a "stained glass" pattern. Students will choose 12 of 24 linear equations, create t-tables to find at least 3 points for each equation, and graph the corresponding line for that equation. All lines must be clearly labeled with the appropriate equation. 12 t-tables + 12 lines = 24 components.

Graphing Linear Equations
	Excellent 7 pts	Good 5 pts	Fair 3 pts	Poor 1 pts
Completeness	Excellent The student completed all 12 t-tables and all 12 lines.	Good 1-2 t-tables and/or lines are missing.	Fair 3-4 t-tables and/or lines are missing.	Poor More than 4 t-tables and/or lines are missing.
Accuracy	Excellent 24/24 or 100% of t-tables AND lines are accurate.	Good 18/24 or 75% of t-tables AND lines are accurate.	Fair 12/24 or 50 % of t-tables AND lines are accurate.	Poor Fewer than 12/24 or 50% of t-tables and lines are accurate.
Work shown	Excellent Work shown for all points in t-tables.	Good Work shown for 10-11 t-tables.	Fair Work shown for 8-9 t-tables.	Poor Work shown for less than 8 t-tables.
Labels	Excellent All 12 lines are labeled accurately.	Good 1-2 lines are labeled inaccurately and/or not labeled.	Fair 3-4 lines are labeled inaccurately and/or not labeled.	Poor Mor than 4 lines are labeled inaccurately and/or not labeled.
Color	Excellent Each area is colored neatly.	Good Most areas colored neatly.	Fair Some areas colored and/or coloring is not neat.	Poor No areas are colored and coloring is not neat.
