Guidelines for marking

The following guidelines for marking show one approach to assigning a value to a student’s work. Other approaches may be used that better suit the reporting process of the school. Categories, marks, grades, visual representations or individual comments/notations may all be useful.

Range	Students in this range:
High	identify and accurately draw different types of special quadrilaterals: trapezium, parallelogram, rectangle, rhombus, square, kite make a valid conclusion about the bisection of diagonals for the different types of quadrilaterals.
Satisfactory	identify and accurately draw at least two special quadrilaterals identify some quadrilaterals for which the diagonals bisect each other.
Progressing	identify and draw one quadrilateral for which the diagonals bisect each other.

Feedback

Students will receive:

• possible prompt questions related to the assessment Activity to assist their engagement
• written feedback on individual responses in relation to the nature of quadrilaterals for which the diagonals bisect each other
• specific advice about strategies to further consolidate knowledge, skills and understanding, and suggestions for completing related additional tasks
• oral feedback (to the class and individuals) related to the overall understanding of the concepts and misconceptions about the mathematical ideas.
