These are some mainly worded Pythagoras and trigonometry (in right-angled triangles) questions that should hopefully get students thinking (and sketching the problem). I came up with the joke myself… I apologise.

Three slides with different differentiation problems. The first asks students to differentiate, find a gradient and equation of a tangent at the given point; the second asks the same but the equation of the normal at the given point; the third asks students to find the turning/stationary points. I have thrown in a bit of integration (by stealth) as well just as a challenge… and this could be used for IGCSE or A/AS Level.

I needed something to go through substitution in a practical sense with students who lack confidence with algebra generally. I cam up with this which is not perfect but gets the baby bathed as it were. It aims to build up in difficulty using taxi fares and then bespoke furniture making and should allow students to gain confidence with substitution.

Answer the questions, link to the letters in the table and then laugh at the “hilarious” joke… you probably know how these work now. This one is on the product rule for counting (doing what it says on the tin).

I had to design something for some visiting Year 6 students so came up with this for a lesson. It is basically how to convert from binary to decimal numbers and vice versa. There is a presentation, a matching activity and a codebreaker to do. Animations sorted (I hope).

Ten questions of increasing difficulty (you can choose which you tackle) where four potential answers are given; one answer is correct (your class can find this) and three answers are incorrect and your class needs to work out how they got it incorrect. Ideal for mathematical discussions. This involves simplifying, rationalising and expanding brackets.

The “Card Sort” sheet is actually the answers, but I have produced a worksheet version if you aren’t keen on the faff of cutting and sticking. I’ve included the sketches in case you want to change anything.

This is aimed at AQA Further Maths Level 2 students but could be used in early A level lessons as something a bit different. Answer the questions, reveal the joke.

This is designed to be non-calculator and was written with the AQA Further Maths Level 2 Certificate in mind, but could also be used for GCSE. It involves simplifying, expanding brackets and rationalising the denominator. The punchline is revealed upon answering all the questions.

This worksheet deals with symmetry of quadratics, where a quadratic function intersects with the y-axis and turning points/vertices of quadratics. It is aimed at Further Maths Level 2 students but could be used at the top level of GCSE as well.

Answer the questions, unjumble the letters and find your next destination.

Three equations, three unknowns; written for the AQA Further Maths Level 2 Certificate course but it could be a nice extension at GCSE. The joke was given to me by a student!

This one does what it says on the tin; designed for AQA Further Maths Level 2 Certificate but could be used at GCSE level too.

Having been over a load of exam papers recently I decided to put together some statements regarding number (odd, even, primes), use of the identity sign, graphs, ratio; there are seven slides in total (plus answers) with increasingly difficult statements to cater for a whole class. The idea is to generate discussion and mathematical thinking, probably at the start of a lesson but use it when you like (if at all).

This does what it says on the tin, nothing fancy. Reveal the joke, which is so bad it’s good…

Find the coordinates based on the information given and reveal the joke. This is designed for the AQA Further Maths Level 2 Certificate course.

This was written with AQA Further Maths Level 2 Certificate in mind but could easily be used for GCSE candidates. The joke is a classic as the students won’t guess it but it is actually quite funny (I didn’t write it, clearly).

Find where the graphs meet and reveal the punchline (this is essentially simultaneous equations). I like this joke…

Three worksheets from the "Defuse The Bomb" series starting from basic stuff up to wordy questions. Hopefully I have corrected a repeat on number 1.

A progress sheet to print out, questions on various topics to check knowledge and focus revision in the places where it's needed. This starts at probability scales (G/1), probability of an event (E/2), expected successes, one event OR another, relative frequency, sample space diagrams (all D/3), tree diagrams (C/4), one event and another (B/5), tree diagrams for independent events (B/6), tree diagrams of dependent events (A/7).
