Impossible Maths - Algebra

Impossible Maths - Algebra

(0)
This is based upon the concept of the gameshow called “Impossible” (I watch daytime TV in the holidays, sadly) where each question has three options: one correct, one partially correct and one impossible. I ask students to find the correct answer and then explain why the other two options are either impossible or only partially correct. This one involves algebra topics like simplifying expressions, factorising, sequences, equations of lines, inequalities, quadratic equations, function notation, rearranging formulae etc. There are twelve questions altogether.
Summer 2021 Codebreaker Bundle

Summer 2021 Codebreaker Bundle

(0)
A bunch of codebreakers (30 I think, with answers) on various topics, including Venn diagrams (probability), set notation, vectors (including calculations), turning points of quadratics (completing the square), transformations, truncation/error intervals, sale prices, properties of number, circle theorems, product rule for counting, identities, midpoints, domain/range of functions, currency conversion, density, capture/recapture. These are good for any stage of a lesson or homework and are easy to mark as they should spell out the punchline to a joke. All these codebreakers are available individually for free.
Truncation Codebreaker

Truncation Codebreaker

(0)
Answer the questions about truncation to reveal the punchline to a cheesy joke. These are popular in class in my experience.
Geometric Sequences Codebreaker

Geometric Sequences Codebreaker

(0)
Answer the questions (including algebraic ones) to reveal the punchline. Ideal for starters, plenaries or a main activity and the students seem to enjoy them.
Equations of Circles Codebreaker 2

Equations of Circles Codebreaker 2

(0)
This is probably more aimed at Further Maths Level 2 Certificate or early A Level but could be a challenge task for GCSE students too. It’s the usual “answer the questions and reveal the punchline”.
Identities Codebreaker

Identities Codebreaker

(0)
Fill in the blanks to reveal the punchline to the cheesy joke. These seem popular with students and can be used as a main task, starter or plenary but you have a brain and don’t need me to tell you how to structure your lessons!
Turning Points (Completing the Square) Codebreaker

Turning Points (Completing the Square) Codebreaker

(0)
The usual thing: answer the questions, reveal the cheesy joke. I use these as starters, plenaries and main tasks; you can use them (or not as the case may be) however you like… but students do seem to like them (if the volume of groans at the jokes is anything to go by).
Integration (Year 2) Codebreaker

Integration (Year 2) Codebreaker

(0)
Integrate the expressions, reveal the punchline… This includes “reverse chain rule”, one integration by parts and where the differential of the denominator is the numerator. A useful starter?
Double Angle Formulae Codebreaker
alutwychealutwyche

Double Angle Formulae Codebreaker

(0)
Convert the trigonometric expressions to the appropriate double angle formula to reveal the anagram of a cheesy joke. I would use this as a starter but obviously use it (if at all) how you wish.
Complex Roots of Polynomials Codebreaker

Complex Roots of Polynomials Codebreaker

(0)
I say polynomials but actually I could only really use cubics, but there you go. Answer the questions (given one real root) and reveal the hilarious joke… I actually quite like this one (so did my form group).
Quotient Rule Codebreaker
alutwychealutwyche

Quotient Rule Codebreaker

(0)
Differentiate the algebraic expressions to find the punchline to a cheesy joke; something different from going through exercises in the book!
Product Rule Codebreaker

Product Rule Codebreaker

(0)
Another cheesy joke revealed upon differentiating some expressions using the product rule. A nice change from going through exercises in the text book.
