Patterns and number facts: Year 9 – planning tool

This planning resource for Year 9 is for the topic of Patterns and number facts. Students bring together knowledge and skills of algebraic and graphical representations of linear functions and quadratic functions. They make these connections by systematically varying the parameters in the rules y = ax + b and y = a(x + h)^2 + k, and exploring the effects of corresponding transformations on the graphs of the basic linear function y = x (reflection in the horizontal axis, vertical dilation, vertical translation) and the basic quadratic function y = x^2 (reflection in the horizontal axis, vertical dilation, vertical and horizontal translation), respectively.
