Generate a Patter
	25 points (N/A)	20 points (N/A)	16.25 points (N/A)	13.75 points (N/A)
Function Table	25 points Function table is written neatly, correctly, clearly understandable.	20 points Function table is written correctly.	16.25 points Function table is written but may have an error.	13.75 points Has an incorrect function table.
Graph	25 points Graph is aesthetically pleasing; scales are present, appropriate and evenly spaced; points from function table are all correctly graphed and fall on a line; the line they determine is drawn correctly	20 points Graph is appropriately labeled on all scales; scales are mostly evenly spaced; points from function table are all graphed with one mistake; the line they determine is drawn	16.25 points Graph is shown, but some scales may not make sense or be spaced correctly; Parts may be missing from graph (i.e. line they determine, points from function table, etc.)	13.75 points Graph does not make sense: scales are wrong or not present, points may be missing, line is not drawn or in incorrect.
Presentation	25 points Shows strong understanding of how to complete a function table using a linear equation and how to graph points taken from the function table.	20 points Shows good understanding of how to complete a function table using a linear equation and how to graph points taken from the function table.	16.25 points Shows a fair understanting of how to complete a function table using a linear equation and how to graph points taken from the function table.	13.75 points Shows either a poor or no understanding at all about how to complete a function table using a linear equation and how to graph points taken from the function table.
Timeliness	25 points Excellent Turned in on time!	20 points Good Turned in a day late.	16.25 points Fair Turned in during the same week.	13.75 points Poor Turned in a week or more late.
