Algorithms: Year 9 – planning tool

This planning resource for Year 9 is for the topic of Algorithms. Students draw upon their knowledge of congruency, transformations and ratios of right-angled triangles and apply creativity, critical thinking and reasoning skills to a sequenced geometric problem. For example, students may design a flow chart to prove the congruency between two triangles, or perhaps they create instructions to design a sequenced visual pattern or use dynamic geometric software to explore three-dimensional (3D) shapes in the x, y, z planes.
