This does what it says on the tin basically; a load of right-angled triangles with missing lengths to calculate and reveal the fish joke. These work in class, online or as a homework task and reassure students as they start to spell a word or sentence.

There are six “Defuse The Bomb” worksheets here involving: one on reflection, one on rotation, one on translation, one on reflection/rotation/translation and two on enlargements (one including fractional, one including negative and fractional). These are designed to create discussion in class, by deciding whether the transformations described are correctly described or not. I have designed these with online learning in mind.

Five “Defuse The Bomb” sheets on area and perimeter including: rectangles/triangles, parallelograms/trapeziums, circles, compound shapes (no circles), compound shapes (including circles). These are designed to give students a bit of confidence as the correct answers appear on the sheet whilst you, as the teacher, can help those who are struggling initially. These have worked well in the classroom and online but could also work as homework tasks.

This is a true or false activity designed to create discussion about stem-and-leaf diagrams. including using them to find the mode, median and IQR. These work well online but also in the classroom.

Students are required to decide whether the 10 statements based upon a cumulative frequency graph are true or false. This is designed to create discussion but also with online lessons in mind.

Six questions where students are given the question and the answer, their task being to add in the workings. The “possible workings” sheet are just there as an example, not as a concrete “it must be done like this”. These are designed to encourage working and method.

Another fish related effort after finding the missing angles using circle theorems. Ideal for online lessons and in-person ones too; students like the cheesy jokes despite their protestations to the contrary.

This is designed to encourage workings; students are given a correct addition or subtraction of fractions and have to fill in the blanks in th workings. I have included a “possible workings” files as well, but I don’t really want to force students down any specific road, only encourage them to get each stage down on paper.

Ten statements regarding a comparative bar chart; students decide whether the statements are true or false. Designed to create discussion and for use in online lessons.

Another fish-related joke after some standard form conversions and calculations. Ideal for online lessons but also in-person lessons.

Calculate the bearings and discover the punchline for a joke involving fish. These have worked really well in online lessons but also before with real-life lessons so enjoy!

There are four “Show that” questions: two linear equations, two quadratics. These are designed to encourage students to write down method and working rather than just reading out an answer at the end.

This involves simplifying surds, expanding two brackets with surds and rationalising the denominator. Some of the" answers" are not fully simplified to encourage students not to use a calculator more than absolutely necessary. This sheet is designed to encourage method/workings and my “possible workings” are just a guide, not a manual!

This is designed to encourage students to explain their working rather than just read out an answer at the end. I have given an example of solutions but these are not the only solutions for each. This should encourage discussion too.

Four “show that…” questions that encourage explanations ahead of final answers (which are already given). These are designed to create discussion and get students to think about the steps they are taking.

Answer the proportion questions and reveal the fish-related joke. These are popular in class, both online and in-person, offering those who are fairly confident the opportunity to get on with an answer being revealed whilst the teacher can help those who need it.

Find the missing angles on a line, in triangles, in polygons and parallel lines and find the punchline to the fish-related joke. These have worked nicely in online lessons and in-person lessons before that. Students gain confidence as words appear and teacher can help those who really need it rather than those who just want to check that they are going right.

Find the letters upon which the shapes land on and uncover the joke on a fish theme. These are popular (no matter the quality of the joke) in both online and in-person lessons.

This (hopefully) shows how your skills at factorising and solving quadratics can enable you to solve other non-linear equations. Initially students must solve three straightforward quadratic equations, then look at a number of other equations that are linked to them, using their initial answers to help solve the more complex equations. This moves on to solving more complex equations. This could be a bridging resource between GCSE and A Level as it involves trigonometric and exponential equations.

Some questions involving bounds leading to an aquatic joke; these seem to be popular in the classroom and online, even though the jokes are of a Christmas cracker standard.
