Binomial expansion

This lesson is designed to build and extend student understanding of binomial expansion through inquiry. Students are encouraged to work collaboratively to pose questions and share their understandings as they practise a procedure, find examples to interpret and change a prompt. They will learn when and how to use different methods to expand binomials. As students become more comfortable, examples become more challenging for students to calculate. The teacher guides and support students as they explore various patterns. Downloadable resources are provided to assist with teaching the topic.
