ITEM SCORE SCALE

0	Answer is unresponsive, unrelated or inappropriate. Answer contains nothing correct.
1	Answer contains something correct. Answer has three distinct polygons or, answer has at least one polygon with all sides correctly measured.
2	Answer has two different (not similar) polygons both os which have a perimeter of 20 cm (+/- 1.5cm.) or, answer has two polygons with all sides correctly measured (but may or may not address a perimeter of 20 cm) or, answer has three distinct polygons and a perimeter of 20 cm is addressed but there is a consistent error in measurement.
3	Answer has three different (not similar) polygons that each address a perimeter of 20 cm and may have a minor error in each polygon (i.e. units for sides not labeled correctly or line segment not within the stated tolerance); or , or answer has three polygons, and two are similar, with everything correct.
4	Answer is complete and correct. Three different kinds of polygons (not similar) are drawn, each line is correctly measured within +/- 3 mm and each polygon has a perimeter shown to be 20 cm.
