Erica makes mistakes; lots of mistakes. You have her homework on every topic covered in the first year of her A level mathematics course where she consistently makes mistakes. Your job, or more accurately, the students in your classes’ job is to correct Erica’s errors and explain where she’s gone wrong so that she doesn’t make the same mistakes again. These have gone down well in my classes and really encourage discussion about the mathematics and should embed a deeper understanding.

Much of this has been copied from GCSE and A Level and parts amended to fit the course. It obviously includes matrices, factor theorem and calculus that don’t appear in the Maths GCSE. Each topic gives the tools required for each topic, a couple of examples and some for the students to do themselves. Modified in the summer of 2020 to include product rule for counting, more on functions, simultaneous equations with three unknowns, trigonometric identities, solving trigonometric equations (including quadratics) and many other things.

This hopefully covers all bases involving fractions, decimals and percentages from simplifying up to converting recurring decimals to fractions and everything inbetween.

A powerpoint taking you from chance and probability lines, listing outcomes, the probabiliy of an event not happening and tree diagrams.

A series of lessons taking students through 'I think of a number' problems to simple equations, equations with brackets to letters on both sides to equations with fractional parts.

These are all available for free but if you want to save time and get them all then here they are. These are general mathematics questions, not on one specific topic. I have used them at the start of term as a "welcome back" but also, in the case of the Christmas and Easter versions, at the end of term. Each contains a joke punchline to find.

This 500+ slide Powerpoint covers all of the first year of the single A Level Pure course (based upon the Edexcel course). It includes explanations, worked examples and questions for students to do. I have included everything, possibly more than you may need but I’d rather give people the option to skip a slide than have to make something up on the spot. I used this during the first year of the new course.

This is around 580 slides including notes, worked examples and questions for students to do on all topics in Edexcel’s Year 13/Book 2 including all the differentiation, integration, trigonometric identities, functions, logarithms/exponentials work as well as everything else. examples and solutions are animated so that each step can be looked at and discussed as is your and/or your students’ preference. Fully editable obviously. Now without differentiating arcsin, arccos and arctan and a rearranged series chapter.

This 270 slide Powerpoint covers all of the first year of the single A Level Applied course (based upon the Edexcel course). It includes explanations, worked examples and questions for students to do. I have included everything, possibly more than you may need but I’d rather give people the option to skip a slide than have to make something up on the spot. Colleagues of mine used this during the first year of the new course. The “Forces and Motion” part has been edited.

A bunch of codebreakers (30 I think, with answers) on various topics, including Venn diagrams (probability), set notation, vectors (including calculations), turning points of quadratics (completing the square), transformations, truncation/error intervals, sale prices, properties of number, circle theorems, product rule for counting, identities, midpoints, domain/range of functions, currency conversion, density, capture/recapture. These are good for any stage of a lesson or homework and are easy to mark as they should spell out the punchline to a joke. All these codebreakers are available individually for free.

Erica is struggling with many aspects of the A level mathematics course and needs help from your students. What you have here is 17 of her homeworks, each with mistakes in solutions which your students need to find, correct and explain where Erica has gone wrong. These are purely designed to generate discussion and to allow students to demonstrate their understanding, whilst also allowing them to show their own methods of solving problems. These are all based upon the new A level curriculum.

All these Christmas-themed worksheets are available for free but if you want them as a bundle then this one covers data and geometry and measures. There are festive worksheets on unit conversion, transformations, area and perimeter, tree diagrams, bearings and distance-time.

This is a booklet of around 180 worksheets covering the GCSE Maths course, each with an accompanying QR code to a short video for those who need a reminder of how to do the questions (the videos aren’t solutions to the questions on the sheet but to similar questions). There are answer sheets at the end so answers can be checked. This includes new elements of the GCSE including iteration, frequency trees, Venn diagrams and other topics. Each section (Number, Algebra, Geometry and Data) is available individually but if you want the whole booklet then this is for you.

Twenty two codebreakers on various topics including bearings, similarity, scale drawing, simultaneous equations (linear/quadratic), circles, angles, transforming functions, metric units, Pythagoras and trigonometry and 3D views. The usual format of correct answers revealing the punchline to a cheesy joke.

A bunch of codebreakers (the usual terrible joke) having solved a load of algebra problems involving functions, arithmetic sequences, inequalities, substitution and other algebra topics. These can be used as a starter or plenary or even part of a main task in a lesson.

These are levelled/graded worksheets covering the GCSE curriculum and split up into topics. Each individual sheet builds from the most straightforward elements of the topic through to the most challenging. At the top of each sheet is a “RAG” table for students to complete before and/or after completing each section; every statement in a RAG table is connected to a section in the sheet. I have produced these for two reasons: firstly to allow my Year 11 students to focus their revision on the areas that will make it most efficient and secondly to have a bank of worksheets available that students can differentiate themselves for any GCSE topic within lessons. These are the Word files to allow for editing. Answers are included.

All these are available for free individually but if you want them all in one lot here you go. Each delivers a (generally lame) joke whilst practising key mathematical skills. I use them for short homeworks, starters and plenaries. Topics include vectors, probability trees, circle theorems, algebraic fractions, histograms, angle properties, trigonometry, simultaneous equations, sets and Venn diagrams. All come with answers.

This is a powerpoint covering basic calculus for GCSE. It contains brief notes by way of an explanation, model answers to questions and a question or two for the students to do; all of the questions come with answers that you can display when ready. The slide show comes with a progress grid (regularly referred to in the presentation) so that students can mark their progress from start to finish and pinpoint any areas that may need extra work with a “red/amber/green” system that they fill in; each one is given an approximate grade in both new (2017 onwards) and old system in England. It’s what I use in my lessons before setting tasks from worksheets or text books to practise.
