Enlargement

A series of lessons designed to build and extend student knowledge on how shapes are transformed and enlarged using various scale factors. A variety of support material is provided to assist with teaching and scaffolding the lessons. The inquiry is structured around student questions and worked examples, and is designed to encourage students to work collaboratively to build mathematical knowledge and to extend themselves. Students are provided with an assessment task where they have the option to choose between three inquiry questions. Students then use their prior knowledge from previous lessons to work through their chosen question. Additionally, downloadable resources are provided to assist with teaching the topic.
