The start of the lesson challenges the class to create the numbers one to ten inclusive using a combination of known operations and four threes. The development phase builds on this by guiding the class to discover the order of operations with the use of a calculator. There are several examples provided for the teacher to formalise and apply the rules of BODMAS.
Differentiated Learning Objectives
- All students should be able to use the order of operations to evaluate calculations in the form a + b x c
- Most students should be able to insert brackets into a calculation in order to evaluate it.
- Some students should be able to make a calculation true through organising its operations including brackets.
