Using A Calculator

There are 366 different Starters of The Day, many to choose from. You will find in the left column below some starters on the topic of Using A Calculator. In the right column below are links to related online activities, videos and teacher resources.

A lesson starter does not have to be on the same topic as the main part of the lesson or the topic of the previous lesson. It is often very useful to revise or explore other concepts by using a starter based on a totally different area of Mathematics.

Notes:

All pupils should learn to calculate accurately, selecting mental methods or calculating devices as appropriate. Pupils, through practice, should learn to use the most appropriate method to perform a calculation. It is appropriate for them to use a calculator when performing a calculation without a calculator will take an inappropriate amount of time.

In addition to simply finding answers, calculators provide a fascinating opportunity for pupils to investigate number patterns, properties and relationships. They can easily use a calculator to learn more about Mathematics through open ended explorations, games and puzzles.

On this website you can find activities which help pupils practise calculator skills and become more familiar with this essential tool whether it be basic, scientific or a graphic display calculator.
