This resource provides the teacher with detailed explanations and worked examples on the following areas of algebraic expression: distributive law, using strategies such as the area model; recognising the relationship between factorising and expanding; and understanding the laws used with numbers can also be used with algebra. Students can access the resource to deepen their understanding of the topic as they read through the worked examples and complete the practice questions presented.
