Generate a Pattern
	20 points (N/A)	15 points (N/A)	10 points (N/A)	5 points (N/A)
Function	20 points Function clearly matches the table.	15 points Function matches part of the table.	10 points Function does not represent the table.	5 points Has no idea of the function.
Function Table	20 points Function table is written neatly, correctly, clearly understandable.	15 points Function table is written correctly.	10 points Function table is written but may have an error.	5 points Has an incorrect function table.
Graph	20 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	15 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	10 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.)	5 points Graph does not make sense: scales are wrong or not present, points may be missing, line is not drawn or in incorrect.
Ordered Pairs	20 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, including the ordered pairs.	15 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 along with the ordered pairs.	10 points Shows a fair understanding of how to complete a function table using a linear equation and how to graph points taken from the function table, some ordered pairs are missing.	5 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, ordered pairs are not present.
