I have been a teacher for over 20 years - all the stuff I upload has been tried and tested in my classroom. I don't mind a discussion on Twitter too where I also share new resources. I now have a personal website: https://andylutwyche.com/

Three codebreakers on relatively straightforward statistical graphs/charts. The jokes are the usual lame stuff but might raise a smirk, you never know. Two are on bar charts and one on pie charts and none will take long but I am planning to use them as starters/plenaries. Errors corrected on the “Bar Charts and Averages” one.
Two codebreakers (the first one is slightly easier than the second) where students must identify the equation of a trigonometric function from the graph, resulting in the punchline to a cheesy joke. The scale is as large as I can make it I’m afraid so I apologise that it is small. I used Desmos to draw the functions.
These are supposed to prevent students using their calculators to do these entirely as they ask for the solution to be in a form that the calculator won’t give exactly. The jokes are predictably cheesy and they get increasingly difficult as you go through them.
There are 10 fairly straightforward questions and four possible answers for each; students are expected to work the correct answer then explain how the other three answers are generated. Whilst the correct answer is shown in the presentation I have purposely not suggested how the incorrect answers were generated in order to encourage discussion and experimentation. I intend to use these as starters/plenaries but obviously you can use them (or not, as the case may be) however you like.
I spotted a gap and have hopefully filled it. The usual “answer the questions to get the punchline” stuff involving conversion between metric units of length, area and volume.
Ten questions, each answered by four people. One of them has got the answer correct, the other three have got it wrong. Students find who got the answer correct then try to figure out what the others did wrong. This should lead to some nice discussion as either a starter or plenary, but you can clearly use it however you like.
This PowerPoint and three codebreakers takes students through bases; this should help students understand why we carry/borrow when calculating mentally.
Three more of the usual stuff; a load of questions that lead to the punchline of a lame joke. Number 1 was done ages ago (when I was doing film titles; yes, that long), in case you were wondering.
I needed something for a lesson on this and drew a blank so created this. It involves converting metres/second to kilometres/hour and vice versa, but also asks two questions converting imperial units to metric with approximate conversions given. It’s the usual format of “find the punchline to a terrible joke”.
Ten questions, each answers by four “students” but only one has got the answer correct; your class’ task is to work out where the other three went wrong. This is designed to be done as a starter or plenary and to create mathematical discussion but you can use them however you like obviously.
We put on a Stem Day for Year 6 students and decided to do binary as the topic for a 45 minute session. This takes students through converting between binary and decimal numbers, including a couple of codebreakers (we produced a Stem leaflet for them to take away). The PowerPoint moves on to adding and subtracting in binary if you need it. It went well and was delivered by a range of people so if it’s useful to you…
There’s even a bonus codebreaker on adding and subtracting in binary.
The usual stuff: answer the questions, find the punchline to a lame joke. This involves one speed-time graph and questions on acceleration and distance (area under the graph).
I have three more of these (obviously) but not one where one must multiply/divide algebraic fractions so I thought I’d write one. The usual terrible joke for students to find.
Twenty-five of the usual stuff (answer the questions, get a terrible joke), written between the dates in the title and covering topics that needed more codebreakers (in my opinion) or pushing a little further. There are plenty of statistical graph ones (box plots, pie charts, bar charts) plus simplifying expressions, surds (partially simplified to avoid calculator use), compound measures, including distance and speed-time graphs amongst other things. Each one comes with answers. Each of these has been uploaded for free as they have been written, so they are yours for free if you want them.
Seven sets of five questions and solutions, some of which are correct and some of which are not, the students decide and explain how they have come to their decision. There are slides on simplifying expressions, substitution, expanding and factorising expressions including quadratics, rearranging formulae and algebraic fractions. These are designed to create discussion in class. Hyperlinks now working!
This is a 220+ slide PowerPoint with notes, diagrams, examples and questions based around the entire Edexcel A Level Applied course. It is obviously fully editable.
