Linear relationships Modeling linear relationships Rubric used to grade linear equations using function tables and graphs. Rubric Code: LX2X3A3 By Jtavarez Draft Public Rubric Subject: Math Type: Assignment Grade Levels: 6-8

Constructing Functions
	Level 4 (N/A)	Level 3 (N/A)	Level 2 (N/A)	Level 1 (N/A)
Equation	Level 4 The equation written in the form of y=mx + b represents the linear description. The slope and y-intercept are clearly labeled.	Level 3 The equation written in the form of y=mx + b represents the linear description.	Level 2 The equation written does not represent the linear description.	Level 1 There is no equation.
Function Table	Level 4 Function table is written neatly, correctly, clearly understandable.	Level 3 Function table is written correctly.	Level 2 Function table is written but may have an error.	Level 1 The function table has multiple errors.
Graphs	Level 4 The graphs are aesthetically pleasing; scales are present, appropriate and evenly spaced. Points from function table are all correctly graphed and fall on a line. The lines they determine are drawn correctly.	Level 3 The graphs are appropriately labeled on all scales; scales are mostly evenly spaced. Points from function table are all graphed with one mistake. The lines they determine are drawn.	Level 2 The graphs are shown, but some scales may not make sense or be spaced correctly.<BR> Parts may be missing from the graphs (i.e. line they determine, points from function table, etc.)	Level 1 The graphs do not make sense. Scales are wrong or not present, points may be missing. The lines are not drawn or are incorrect.
