# GCSE

## TEACHERS

Students will need access to at least trigonometric functions. The minimum-requirement scientific calculator is the fx-83GT PLUS / fx-85GT PLUS. This has all the functionality required for GCSE. However the advanced scientific calculator fx-991EX will give students advantage for both learning and the exam in solving equations. Please see below to compare these calculators.

Maths is a visual subject. A graphic calculator allows students to draw graphs and statistical charts, as well as make the same calculations as a scientific calculator. Some schools now use our fx-CG50 graphic calculator which gives a significant learning advantage, especially at the Higher tier. Please see below on why it might be worth considering this calculator.

## WHICH SCIENTIFIC CALCULATOR?

While the fx-83GT PLUS / fx-85GT PLUS is adequate for GCSE, the advanced scientific fx-991EX confers specific advantages. In particular, it builds students confidence in solving equations, and offers the opportunity to check exam answers. In addition to all the functionality of the basic model, it will allow students to check answers to

- linear equations
- simultaneous linear equations
- roots and vertices of quadratics
- quadratic inequalities

## SHOULD I USE A GRAPHIC CALCULATOR?

Maths is a visual subject. A graphic calculator allows students to explore graphs. For example you could plot a graph, find the coordinates where two graphs cross or draw a data chart.
