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	demonstrate knowledge and understanding of a range of methods for solving simultaneous equations and checking solutions
Satisfactory	correctly use at least one method to solve the equations for x and y, but make an error in checking solutions
Progressing	correctly use a method to solve the equations for x or y OR demonstrate understanding of an appropriate process for checking solutions.

Feedback

Students will receive:

• possible prompt questions related to the assessment Activity to assist their engagement
• written feedback on individual responses in relation to different methods for solving simultaneous equations and checking solutions
• 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.
