Laws of arithmetic

This resource guides and supports the teacher to explicitly teach the laws and properties of arithmetic using algebraic terms and expressions to model examples. Students can use the resource to guide their understanding to identify order of operations in contextualised problems, preserving the order by inserting brackets in numerical expressions, then recognising how order is preserved by convention. They can follow through the examples presented and complete practice questions.
