The task

The teacher asked the students to:

• copy the pattern shown and draw the next element
• describe and use rules to predict subsequent elements of the pattern.

Prue's work shows that she is able to:

• use algebraic notation to state rules for any element of a pattern
• use algebraic conventions correctly: "n x n = n² ".

Keanu's work shows that he is able to:

• identify rules for a pattern
• use algebraic notation to express the rules.
