Solve the simultaneous equations to reveal the punchline to a lame joke in both cases. The equations on codebreaker 1 are all designed to be solved by elimination; the equations on codebreaker 2 are to be done by substitution.

This designed to help students unravel and solve quite complex equations. It could also lead to in-class discussion and there are templates/blank slides to do your own should you wish. The initial idea came from a colleague (thank you Mr Steve...).

This covers basic differentiation, finding gradients at given x values but could be used to introduce integration plus moves on to negative and fractional powers of x. Could be used at Core 1 (or whatever they are going to call it when it changes) and with the new GCSE.

The predictably lame joke upon answering the histogram questions. The first part involves calculating from a frequency table and the second involves reading a histogram.

Four lame jokes to discover (a couple with help from Tim Vine) based around logarithms. I use these as starters to get the students in the logarithm mood but use them as you wish. They cover simplifying, and use of the laws.

This is designed to test all aspects of y=mx+c. There are 4 different "explosions" of increasing difficulty that should encourage discussion in class and hopefully develop deeper understanding of the concept of equations of lines.

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.

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 Christmas-themed idea I came up with where students answer the questions (the solutions are 1 to 24) and each answer links to a word; put the words in numerical order and an entire joke is revealed! My students are actually enjoying them quite a lot.

Two trigonometry codebreakers that both involve a terrible joke. The first one is with right-angled triangles, the second requires the sine rule, cosine rule and area of a triangle using trigonometry.

One of these (an "Advent calendar") is available for free but not all I'm afraid but there are a variety of new Christmas maths resources including two new codebreakers and two transformation codebreakers all of which contain a lame joke to discover. On top of this are my new idea which are five new "Advent Calendars" where you answer 24 questions to get a festive joke as a prize. There is also a festive graphs activity involving linear graphs (y=mx+c) and quadratic graphs. I have used these in response to being told to "teach curriculum up to the holidays" and the students seem to like them.

This worksheet has six questions and eight answers to choose from (this is to avoid students guessing the final answer/answers) so that Santa can rest two reindeer for each trip. This one covers linear sequences (finding their nth terms) and contains an answer sheet. I use these as starters/plenaries or as "prove you can do this topic" sheets. I have used them as quick homework tasks too.

This worksheet has six questions and eight answers to choose from (this is to avoid students guessing the final answer/answers) so that Santa can rest two reindeer for each trip. This one covers parallel and perpendicular lines and contains an answer sheet. I use these as starters/plenaries or as "prove you can do this topic" sheets. I have used them as quick homework tasks too.

A colleague told me that I didn’t have anything on gradient and so I produced this. The worksheet hopefully leads students from finding a gradient of a line to drawing a line given its gradient to finding the equations of lines and so on. There are 8 sections and a challenge in each section to allow students to prove that they are capable of some quite complex mathematics. It ends with finding the equation of a line given two points on that line but is designed for you to drop in and out at a place of your choosing. Typo corrected!

Each of these 20 worksheets has six questions and eight answers to choose from (this is to avoid students guessing the final answer/answers) so that Santa can rest two reindeer for each trip. I have covered all sorts of number topics from fractions (adding, subtracting, multiplying, dividing, of an amount), percentages (of an amount, increase/decrease, repeated change), ratio (simplifying and sharing), indices (simplifying, negative and fractional) and negative numbers. I use these as quick starters/plenaries or as "prove you can do this" sheets. I have used them as quick homework tasks too. Answers are provided for each.

These are homework sheets which also contain a QR code to a tutorial video if the students require. I have used similar before and parents (and children) have found the QR code very useful and should avoid the “I don’t get it” excuse as they can get help via the QR code. The tutorials have been made using the app Explain Everything if you are interested. Topics covered include negative numbers, order of operations, percentages (of an amount, change etc), HCF, LCM, proportion, recurring decimals, standard form, surds and bounds. Each comes with answers too.

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. Now with contents page and updated in December 2018!

The mandatory terrible joke revealed by finding some partial fractions. Sheet 2 involves the cover up rule and both involve fractional as well as negative numerators.

This goes from discovering how c and m "work" in y=mx+c and then takes them through finding the gradient, finding an equation given a line, plotting a line from an equation and finally finding the equation given two points on the line. At the start of the sheet is a RAG analysis for them to demonstrate progress and target what they need to focus on.

This contains 4 solving equations activities of increasing difficulty. This encourages discussion and insists upon students showing their working.
