Algebra Modelling
	Poor 1 pts	Fair 2 pts	Good 3 pts	Very Good 4 pts	Excellent 5 pts
Constructing Equations	Poor Equations have few correct elements or little correct notation.	Fair 1 equation correctly represents a given situations.	Good 2 equations correctly represent 2 situations.	Very Good Equations represent the situations with minor errors in notation.	Excellent All equations efficiently represent the situations with correct notation.
Constructing Graphs	Poor Linear graphs have not been competed and/or have significant errors in construction.	Fair Linear graphs show an incorrect use of scale and lack an appropriate title and/or axis labels.	Good Linear graphs are satisfactorily drawn with a minor error in use of scale.	Very Good Linear graphs are correctly draw with one error out of the following: no title; no axis labels.	Excellent Linear graphs are correctly drawn with a title, all axis labels and show a correct use of scale.
Applying Knowledge	Poor A very limited ability to select and communicate strategies has been demonstrated.	Fair Selection and communication of strategies has been attempted with varying levels of success.	Good Selection and communication of strategies has been attempted with a sound level of success.	Very Good Appropriate strategies have been used and communicated.	Excellent Efficient and appropriate strategies have been used and communicated clearly.
Drawing Conclusions	Poor Conclusions show a very limited ability to make generalisations with supporting arguments, or have not been attempted.	Fair Conclusions show an attempt to make generalisations with supporting arguments.	Good Conclusions show an ability to make some generalisations with supporting arguments.	Very Good Conclusions predominately show an ability to make generalisations with supporting arguments.	Excellent Conclusions consistently show a strong ability to make generalisations with supporting arguments.
