# Using Calculator Efficiently

The start of the lesson reviews basic calculator operation using the order of operations and place value to calculate the largest product possible. The development phase builds on this by introducing the squared, square root, brackets and fraction buttons on a scientific calculator.  Students then use the rules of BODMAS to break down the calculations and round their solutions to an appropriate degree of accuracy.
##### Differentiated Learning Objectives
