Speck in the Sea
	Poor 1 pts	Fair 5 pts	Good 8 pts
Graph labels	Poor The graphs have no labels.	Fair The graph includes labels but is missing some labels.	Good The graph includes all necessary labels including arrows, linear inequalities and box scale.
Inequalities; shading, line weight	Poor The inequalities have more than 2 mistakes.	Fair The inequalities have between one and two mistakes, including shading, and line weight.	Good The inequalities have no mistakes.
Linear inequalities, slope, y-int	Poor The linear inequalities are graphed with more than 2 mistakes.	Fair The linear inequalities are graphed with between 1 and 2 mistakes, including slope, y-intercept.	Good The linear inequalities have no mistakes.
Neatness	Poor The graph is illegible.	Fair The graph is legible but information is hard to read.	Good The graph is easily read and a solution area is clear and easy to find.
Reflection	Poor The project contains no reflection.	Fair The reflection only describes procedure not process.	Good The reflection clearly shows thought process and describes how linear inequalities could be used.
