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  - Function Notation (True or False)

Defuse The Bomb - Function Notation (True or False)

(0)
Ten statements about functions that students need to decide whether they are true or false. This involves substituting, inverse, composite and domains so covers most the what they could be faced with in an exam. These have created nice discussions in class for me and I always get them to correct the false statements.
Defuse The Bomb - Linear Graphs (True or False)

Defuse The Bomb - Linear Graphs (True or False)

(0)
One sheet with three lines and ten statements about coordinates on the graphs, gradient y-intercept and their equations where students need to decide whether the statements are true or false, correcting the false ones (and explaining where the misconception arose?). These have produced really nice discussion in class and online in my experience.
Defuse The Bomb - Averages From Tables (True or False)
alutwychealutwyche

Defuse The Bomb - Averages From Tables (True or False)

(0)
Two sheets with ten statements on each where the students in your class have to figure out whether they are true or false. One sheet involves a frequency table and the other a grouped frequency. These are designed to encourage discussion in lessons.
Defuse the Bomb - Metric Measures

Defuse the Bomb - Metric Measures

(0)
Four of these sheets covering: capacity, mass and length plus one true or false activity involving problems with all three which should encourage discussion in class and force students to read the question carefully if nothing else. These have worked well in class and online allowing the teacher to help those who need it whilst other get on, reassured that their answers are on the sheet.
Defuse The Bomb - Functions

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.
Everyday Maths

Everyday Maths

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.
Percentages Chordbreaker

Percentages Chordbreaker

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!
Measures Chordbreaker

Measures Chordbreaker

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.
Defuse The Bomb - Sequences

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.
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 - Rounding
alutwychealutwyche

Defuse The Bomb - Rounding

(0)
Three sheets: one on rounding to 1,10,100, one on rounding to decimal places and one on rounding to significant figures. Answers are on the sheet but there are more answers than questions meaning that guessing less of an option and students can get on in the knowledge that their answer should be on the sheet somewhere. These have been useful in online lessons as well as “normal” lessons.
Column Vectors Codebreaker

Column Vectors Codebreaker

(0)
Answer the questions regarding column vectors and reveal the punchline to a cheesy joke; popular in class and online despite the cheesiness of the jokes, which is a surprise if I’m honest!
Defuse The Bomb - Algebraic Proof

Defuse The Bomb - Algebraic Proof

I needed something for this topic and this is what popped out. Whilst it is a true or false activity I would expect some good discussions to arise whilst doing this, with conversations along the lines of “how could we make this statement true?” either by changing the wording or the initial algebraic expression. I have found these activities really quite successful in online lessons as well as “normal” lessons.

Answer the Maths questions and reveal the punchline to a fish-related joke. These ahve gone down really well in online lessons but went down well in “normal” lessons before. Topics include angles, area, bearings, simultaneous equation, Venn diagrams, quadratic equations, Pythagoras, trigonometry and many many more on the 45+ tasks, each with answers.

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.
