Maths Made Easier with the Right Tools
Recommended Maths Tools
Over 16 years of teaching, I’ve tested every calculator, flashcard, and protractor under the sun — and these are the ones I genuinely recommend for GCSE Maths success.
These are affiliate links below, but everything here is something I use myself or have seen work brilliantly for my students. I've also searched to find the best deals to get you the cheapest price I can find.
The Only Calculator You’ll Ever Need
Casio FX-991CW+
The Casio FX-991CW+ is the newer version of the FX-991CW (which is itself the newer version of the FX-991EX). All three calculators are great, but the CW+ is my top pick.
The EX has been discontinued, and there are loads of fakes, making it extremely difficult to find a genuine one. The original CW has a few issues (like needing to press 3 buttons to convert fractions to decimals rather than 1), and the CW+ has resolved all these issues, and added a few extra hacks too (like HCF and LCM).
Here are two trusted links where you can get the CW+ right now, and start learning my calculator hacks for an instant boost in grades 😁

ThE Easiest Way to Revise on the Go
GCSE Maths Flashcards
Perfect for quick-fire revision sessions, these flashcards help students memorize formulas, keywords, and exam tricks — without screens or stress.
I recommend using them for 5–10 minutes a day — it adds up fast.
Helix 360° Protractor
So many students still use a 180-degree protractor (half circle). Get a 360-degree one (full circle) and the whole topic called 'Bearings' becomes a breeze. Just line the 0 up at the top, pretend it's a clock (move the arm clockwise), and read off the bearing.
Get this protractor and you'll save your teen a whole topic on their GCSE's 😁

Helix Oxford Compass
This is the best compass I’ve used.
It's solid, smooth, and doesn't slip mid-circle.
No student is going to get excited about a compass, but they'll definitely get frustrated with a bad one!
