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/

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.
There are twelve transformations here, all of which have more than one solution; this asks students to find as many solutions that work, including reflections, translations, rotations and enlargements with negative scale factors. I did this with a class and offered rewards for any solutions I hadn’t listed which seemed to motivate them even more! Solutions are on a separate slide to enable printing.
Four slides of four questions where you are given the answer but the question is missing some important information. Students must work out what information would work there; some have just one answer, some have many answers. This is designed for students to demonstrate their understanding and to create discussion.
Students are give the answers but there are parts missing in the question; students must decide what should go in the blanks. This should cater for all ages and abilities at secondary (and some primary) and lead to discussion in classrooms. There are four slides of four questions and suggested values/expressions.
Four slides each containing four questions with parts missing but an answer to reach meaning that students have to demonstrate their understanding by filling in the blanks. This is designed to create discussion.
The usual answering of maths questions reveals the punchline; my classes like these and in this time of remote learning they are easy to mark! This involves set notation with three sets in some questions. Mistake on the last question now corrected!
Four slides each containing four inequalities questions where students are given the answers but are missing parts of the question; their job is to fill in the blanks. This should allow students to demonstrate their understanding as well as encouraging discussion as some of the blanks could be filled with numerous different values. This involves solving, satisfying (number lines etc), regions etc.
This is four sets of four questions on statistics, mainly involving statistical graphs including pictograms, bar charts, pie charts, frequency diagrams, scatter graphs, cumulative frequency, box plots and histograms. They get increasingly more difficult as you work your way through them. The answers are given but elements of each question are missing in each case and students are required to fill in the blanks so that the questions work. This is designed to create discussion and allow students to demonstrate that they can interpret statistical graphs.
This is a variation on a codebreaker; unfortunately the software (PowerPoint) won’t let me reflect words, but it will let me rotate them. The shapes fit together when transformed correctly and the words should form a cheesy joke.
Clive is having a go at some revision tests on some basic algebra, including simple algebraic fractions, like terms, expanding brackets, solving linear equations (including with variables on both sides), expanding two brackets and substitution. He has made a mistake on each question; your class needs to spot the error, correct it and then explain what it is. These are designed to encourage discussion in class and develop deeper understanding using common errors.
Two vectors codebreakers with cheesy jokes having answered some questions. My classes like these and I’ve been using them whilst remote learning as they are easy to mark and the students know whether they are right or not straight away or almost straight away.
Clive has a homework on function notation involving domains, ranges, inverses and composite functions. He has, as per usual, made errors that your class can find, correct and explain so that Clive learns from his mistakes. These are designed to create discussion in class and this one could be used as a transitional activity between GCSE/IGCSE and A level.
The name of these was born out of a typo (obviously) but it’s the usual format: do some maths (solve equations in this case) to find the punchline to a cheesy joke about fish, hence the “codbreaker”. Good for a starter, main activity or a plenary in my experience and the students enjoy finding the punchline, especially being the first to do so. This involves anything from two-step equations to variables on both sides including fractional parts. Number 2 is more challenging than number 1.
