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	present valid arguments/proofs for all four of the statements identify at least one other valid result involving surds
Satisfactory	present valid arguments/proofs for at least one (but not all) of the statements identify at least one other valid result involving surds
Progressing	present valid arguments/proofs for at least one (but not all) of the statements OR identify at least one other valid result involving surds.

Feedback

Students will receive:

• possible prompt questions related to the assessment Activity to assist their engagement
• written feedback on individual responses in relation to justifying and identifying results involving surds
• 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.
