Why use calculators?

Used appropriately, calculators are an invaluable tool in today’s maths classroom. They can be used to promote deeper understanding of many maths concepts for example in investigating the properties of numbers or in speeding up rote calculations as part of a much deeper learning activity. It is important that students are proficient in using their calculators and it is also important that students understand the calculations they are doing rather than blindly keying in figures. Students should be encouraged to develop checking strategies so that they have some way of recognising an answer as being reasonable or not. Here is a brief overview of the importance of calculators to students’ maths education.
