This lesson consists of:
A Starter consisting of a series of progressively harder, multi-step calculations and revision of common factors, common multiples and prime factors. A connect activity getting children to begin to understand why it is necessary to have a specific order when undertaking multi-step calculations.
An Interactive Whiteboard teaching introduction for both Notebook and ActivInspire flipchart, to teach how to apply BODMAS to brackets and orders / powers. This includes a PowerPoint presentation showing defining, explaining and applying BODMAS to two different calculations.
A 4-way differentiated series of tasks requiring children to use BODMAS to carry out multi step calculations with all four operations, with brackets, squared and cube numbers and how to balance equations. A stretch challenge including square roots. Answer sheet provided to support marking.
A final AFL / Next Steps task, asking children to correct mistakes in 3 multi-step calculations.
