Picture This Enter rubric description
	Does not meet expectations 1 pts	Not so good, below expectations 2 pts	Good 3 pts	Very Good 4 pts	Excellent 5 pts
Appearance and Visual appeal Graph is constructed neatly, points are evident and neatly plotted, and the lines are joined neatly.	1 Criteria is not met in all three components, but a recognizable picture is produced.	2 None of the criteria was done neatly and this distracts from the overall appearance of the picture.	3 One or two components of the criteria could have been done more neatly.	4 All criteria are done neatly, creating a smooth and very recognizable picture.	5 All criteria are done neatly, creating a smooth and very recognizable picture and<BR> goes above and beyond what was asked. Exceeds all requirements.
Graph and Plotted Points The graph is constructed according to instructions, points are evident and correctly plotted. The lines connect points in the sequence listed.	1 There were many errors in the graph layout, plotting of points, connection of the points.	2 There were several errors in the graph, plotting and/or connection of the points.	3 There were a few errors in the graph, plotting and/or connection of the points.	4 There were a couple of small errors in the graph, plotting and/or connection of the points.	5 There were no graph, plotting or connection errors evident.
Polygons Polygons are clearly defined and plotted correctly. Student selected their own shapes.	1 One polygon was created without dimensions.	2 There were several errors in the polygon, plotting and/or connection of the points.	3 There were a few errors in the creation of polygons.	4 There were minor errors with the polygons, and none were irregular.	5 Three or more correct polygons were made.
Areas of Polygons The area of each shape is indicated.	1 Areas are not done at all.	2 There were several errors in calculating the areas.	3 At least one of the areas were found.	4 More than one area was found.	5 The area was done for three or more polygons.
