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/

Gradients of Lines Codbreakers

Gradients of Lines Codbreakers

(1)
Two fish jokes to find involving gradients: one short one with lines and one where students have to find the gradient between two points. These work in class, online or as homeworks and seem quite popular.
Surds (Expanding Brackets) Codbreaker

Surds (Expanding Brackets) Codbreaker

(0)
Yet another fish pun (this one was made up by me!) involving expanding and simplifying two brackets with surds. Students seem to like these in all setting and I have used these in the classroom, during online lessons and as a homework so they are pretty versatile.
Defuse The Bomb - Transformations

Defuse The Bomb - Transformations

(1)
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.
Crack The Safe - Decimals (Calculations, Equivalence, Recurring)

Crack The Safe - Decimals (Calculations, Equivalence, Recurring)

(1)
Three “Crack The Safe” activities on decimals (stuff related to decimals). There is one on calculating with decimals, one on equivalent fractions, decimals and percentages and one on recurring decimals. These contain six questions but ten possible answers (bar the equivalence worksheet) meaning that students can self-check their answers (are they in the list of possible answers?) whilst the teacher can help those who require it. I use these as starters and plenaries but that is obviously up to you.
Equations Manipulation

Equations Manipulation

(1)
Inspired by an idea @McGuirea499 posted on Twitter I thought I would write these. There are two; the first gets students used to the idea of changing one particular aspect (this could be pushed into generalisations if you like) and the second allows students to pick one element of an equation to fulfil a numerical property in the solution. There are obviously loads of different solutions for each task so discussion should evolve as a result. I have given examples of answers and left a template slide on each so you can design your own if you wish.
Defuse The Bomb - Tree Diagrams

Defuse The Bomb - Tree Diagrams

(1)
Students must work out whether statement is true or false regarding the tree diagram. These sheets work well online in my experience as they can be done from the screen. This involves a tree diagram where the second probability is conditional upon the first.
Factorising Quadratics (a>1) Codbreaker

Factorising Quadratics (a>1) Codbreaker

(1)
We’ve had a bit of an obsession with factorising quadratics with a coefficient of x squared greater than 1 at school this week so I produced this codbreaker to add a fish pun to the mix. They do get quite challenging but that’s kind of the point…
Probability Codbreaker
alutwychealutwyche

Probability Codbreaker

(1)
A little bit of mutually exclusive but otherwise normal probability question all to discover a probability related fish gag. These work in class, online or as a homework.
What Was The Question? - Angles Edition
alutwychealutwyche

What Was The Question? - Angles Edition

(1)
This has been half-complete for a while but I am looking for some more reasoning resources so decided to finish it. This involves the usual angles issues (on a line, around a point etc) as well as polygons and a slide of circle theorems.
Circles (Circumference and Area) Codbreaker
alutwychealutwyche

Circles (Circumference and Area) Codbreaker

(1)
Here’s another one; answer the questions and reveal a rather nice fish-related pun. This involves circumference and area of circles, including fractions of circles at the end. Ideal for classroom, online or homework activities.
Defuse The Bomb - HCF and LCM (including Prime Factors)
alutwychealutwyche

Defuse The Bomb - HCF and LCM (including Prime Factors)

(1)
This is a sheet which involves eight questions with answers given on the sheet (there are ten potential answers for the eight questions to avoid guessing). These have worked well for online schooling and allow students who are reasonably confident to get on as their answers appear on the sheet. In the meantime the teacher can help those who are less confident.
Defuse The Bomb - Probability (Single Event)
alutwychealutwyche

Defuse The Bomb - Probability (Single Event)

(1)
These are designed to allow those students who are confident to get on, checking hat their answers are on the sheet whilst the teacher helps those who need it. There are 6 questions but 10 possible answers.
