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/

Defuse The Bomb - Probability Scale
alutwychealutwyche

Defuse The Bomb - Probability Scale

(0)
Eight questions with ten possible answers. These allow the students who understand the topic to move on with the confidence of seeing their answers on the sheet (screen for online lessons) whilst the teacher can help those who need it.
Defuse The Bomb - Probability (Mutually Exclusive)
alutwychealutwyche

Defuse The Bomb - Probability (Mutually Exclusive)

(0)
Two situations regarding mutually exclusive events with six questions and ten potential answers. These are useful for students to get on and check that their answers are on the sheet whilst the teacher can help those who are completely stuck.
Defuse The Bomb - Probability (Two-Way Tables)
alutwychealutwyche

Defuse The Bomb - Probability (Two-Way Tables)

(1)
I needed something on two-way tables that wasn’t just creating and filling them in so produced this. There are ten statements which students must decide whether they are true or false; there are also blanks in the table for them to fill in. These have been working well in online lessons hence I’m am writing these at the moment!
Clumsy Clive On Histograms

Clumsy Clive On Histograms

(1)
Clive has a histogram homework for your students to check. These are designed to get students discussing and thinking about the mathematics. I have also designed this to work online as there is minimal drawing involved (although there is a little).
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.
Defuse The Bomb - January 2021 Bundle
alutwychealutwyche

Defuse The Bomb - January 2021 Bundle

(0)
There are 28 Defuse The Bomb worksheets here, each with answers. These are designed to allow students to get on if confident enough to do so with the answers appearing on the sheet enabling the teacher to help those who require it. These have worked well with online lessons. Topics include algebraic fractions, area and perimeter, transformations, HCF/LCM, related calculations, simultaneous equations and surds. Each of these is available for free individually.
HCF amd LCM Codbreaker
alutwychealutwyche

HCF amd LCM Codbreaker

(1)
Another fish-related joke to discover once the HCF and LCM questions are answered. These work well online but also in the classroom and the students seem to enjoy discovering the joke no matter how cheesy. The reassurance of the spelling of a word allows students to get on.
Simplifying Ratio Codbreaker
alutwychealutwyche

Simplifying Ratio Codbreaker

(0)
Students must answer the questions on simplifying ratios to reveal the punchline to a cheesy fish-related joke. These work well both in class and online as students who are confident just get on with the words revealed whilst teacher can help those who need it.
Defuse The Bomb - Solving Quadratics
alutwychealutwyche

Defuse The Bomb - Solving Quadratics

(0)
Two worksheets here; the answers appear on the sheet but there are just 6 questions but 10 answers to avoid guessing towards the end. These enable confident students to get going whilst a teacher can help those who are less confident. They have worked well online for me…
Solving Quadratics Spiders
alutwychealutwyche

Solving Quadratics Spiders

(0)
There are six “spiders” each with four increasingly challenging quadratics to solve, including completing the square and using the quadratic formula. Different blanks are left for students to fill in, working forwards to the solutions, backwards from the solutions, from partially complete questions and a mixture of all three. These have been very useful in online lessons.
Defuse The Bomb - Box Plots
alutwychealutwyche

Defuse The Bomb - Box Plots

(0)
There are 10 statements for students to decide whather they are true or false regarding a pair of box plots. This should encourage mathematical discussion and these sheets seem to work well online too.
Defuse The Bomb - Truncation and Rounding (non-traditional amounts)
alutwychealutwyche

Defuse The Bomb - Truncation and Rounding (non-traditional amounts)

(0)
Two more rounding-based tasks; answers are on the sheet but more than the number to questions to make guessing less easy but also allow those who have the confidence to continue without the need to ask the teacher to check, allowing the teacher to help those who actually require it. The truncation sheet also contains error intervals.
Defuse The Bomb - Sequences
alutwychealutwyche

Defuse The Bomb - Sequences

(0)
There are 6 sheets here covering finding the next term in a sequence, using the nth term, finding the nth term (arithmetic and quadratic), summing arithmetic and geometric sequences. These all contain the answers but there are more answers than questions to discourage guessing. this style of sheet has worked well both online and in classrooms in my experience and means that teacher can help those who require it whilst others get on, checking that their answers are on the sheet.
Measures Chordbreaker
alutwychealutwyche

Measures Chordbreaker

(0)
A music joke, hence the name (a suggestion from a very keen musician that I teach). Answer the questions involving metric measures and reveal the joke; popular in both online and real-time lessons.
Probability Scale Codbreaker
alutwychealutwyche

Probability Scale Codbreaker

(1)
Answer the probability questions, link them to the probability scale and unjumble the punchline to a fish-related joke. These have worked really well in online lessons, but also work well in in-person lessons, despite the groans regarding the jokes…
Percentages Chordbreaker
alutwychealutwyche

Percentages Chordbreaker

(0)
Another music-based joke to work out; this involves percentage of a number, percentage change and reverse percentages. Popular in class and online; the music concept from a student I teach!
Everyday Maths
alutwychealutwyche

Everyday Maths

(1)
This is a whole set of lessons based around Maths in the real world: currency conversion, deals in shops, sales, tax, misleading statistics, ratio and proportion (recipes) etc. Each section has separate resources. I have put everything into one PowerPoint (“Whole”) but also uploaded them separately in case people want them individually. It is not supposed to get in to fine detail but just open student eyes to Maths that appears in day-to-day life just a little.
Defuse The Bomb - Functions
alutwychealutwyche

Defuse The Bomb - Functions

(0)
There are four sheets that each tackle a different skill using functions: substitution, inverse, domain/range, composite. The answers appear on the sheet so that confident students can self-check and not bother the teacher too much, whilst said teacher (presumably you) helps those who require it. These have worked well both in class and during online lessons.
Integration (Year 1) Codebreaker
alutwychealutwyche

Integration (Year 1) Codebreaker

(0)
Indefinite integrals using the skills learned in Year 1 of the Edexcel A Level course that reveal a lame joke. These are a nice break from ploughing through a text book!
