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/

Midpoints Codebreaker
alutwychealutwyche

Midpoints Codebreaker

(1)
Find the midpoints, discover the cheesy joke. I realised that I had too few resources on midpoints for a lesson on them, hence this. These are good for starters, plenaries, main tasks or homeworks as they spell something out so students know quickly whether they are going in the right direction.
Algebraic Fractions Codbreaker
alutwychealutwyche

Algebraic Fractions Codbreaker

(0)
Another fish joke discovered having written and simplified some algebraic fractions as a single fractions. Ideal for starters, plenaries, main tasks and homeworks; they are surprisingly popular given the standard of joke…
Quadratic Inequalities Codebreaker
alutwychealutwyche

Quadratic Inequalities Codebreaker

(0)
Another one of these; solve the quadratic inequalities and reveal the joke. Ideal for students at home or in school as the fact that it spells out a short sentence means that they know whether they are doing it right; they also like the competitive nature of getting to the end first in my experience.
Generating Coordinates From Equations Of Lines Codebreaker
alutwychealutwyche

Generating Coordinates From Equations Of Lines Codebreaker

(0)
Find the missing values in the coordinates given the equation. The joke is a classic but will make the students groan. These are ideal for class or homework tasks as the students will know whether they are going correctly because the words will begin to form; they also like the competitive nature of getting to the answer first.
Generating Points On Curves Codebreaker
alutwychealutwyche

Generating Points On Curves Codebreaker

(0)
Ultimately this is a substitution exercise that reveals a joke. These seem popular with students who like getting the joke first and can be used in most classroom/homework situations. This involves mainly quadratic curves but also a couple of cubics and a reciprocal.
Substituting Codbreaker
alutwychealutwyche

Substituting Codbreaker

(0)
Substitute the given values into the expression to reveal the fish pun; good for class or homework and ideal for online learning.
Midpoints and Distance Between Two Points Spiders
alutwychealutwyche

Midpoints and Distance Between Two Points Spiders

(0)
Four “spiders”: two on midpoints, two on finding the distance between two points. Midpoints: some questions ask students to find the midpoint, some give the midpoint and one coordinate. Distance: the first spider asks students to find distance (the final question asks students to find a points a given distance from another point). The second gives one point and a length; this could lead to a discussion on Pythagorean triples. Suggested/examples of answers are given where there are multiple options.
Compound Measures Codbreaker
alutwychealutwyche

Compound Measures Codbreaker

(0)
This contains questions on speed, density, pressure and population density, with questions getting increasingly challenging as you go through. These sheets seem popular with students and are ideal for working in school or from home.
Density Codbreaker
alutwychealutwyche

Density Codbreaker

(0)
Answer the questions, reveal the fish-related joke. You know how these work by now. Ideal for online lessons, homework or in class tasks.
Deriving Algebraic Area Formulae
alutwychealutwyche

Deriving Algebraic Area Formulae

(0)
I needed something for deriving formulae and came up with this. There are some that take students through the process by the hand and then four at the end that ask students to go solo (as it were).
Pressure Codbreaker
alutwychealutwyche

Pressure Codbreaker

(0)
Various questions involving pressure, including converting between different measurements of pressure. The joke is related to fish hence the name of the resource. These are ideal for online lessons, homeworks or in class.
Population Density Codbreaker
alutwychealutwyche

Population Density Codbreaker

(0)
A fish joke after some population density questions are answered correctly; like a dream come true for many, I’m sure… Ideal for in class, homework or online. As the answers spell out a word or short sentence students know if they are going right or need help.
Arithmetic Sequences Codbreaker
alutwychealutwyche

Arithmetic Sequences Codbreaker

(0)
Summing arithmetic sequences and various other things arithmetic sequence related. The usual answer questions then unjumble the letters to reveal a fish joke. Ideal for in class or at home.
Percentage Change Codbreaker
alutwychealutwyche

Percentage Change Codbreaker

(1)
Another fish joke, another set of maths questions to answer. This involves increase/decrease, finding the percentage change, reverse percentages and one repeated percentage change question. Ideal for both classroom and online tasks or a homework.
Deriving Perimeter and Area Formulae Spiders
alutwychealutwyche

Deriving Perimeter and Area Formulae Spiders

(1)
Three “spiders”: one on perimeter and two on area. Each slide contains six questions; four contain a diagram from which a formula needs to be derived and two contain a formula where students can draw their own diagram (this should lead to interesting discussions and thought processes).
Rearranging Formulae Codbreaker
alutwychealutwyche

Rearranging Formulae Codbreaker

(0)
Rearrange the formulae and reveal the joke (generous description in fairness). These formulae are not particularly tough to rearrange but should get across the principles of it; the subject only appears once in each case. Ideal for classroom activities (main task or starter/plenary) but I have used them for online lessons and homeworks as well.
Speed, Distance, Time Codbreaker
alutwychealutwyche

Speed, Distance, Time Codbreaker

(1)
Answer the questions, match to the letters and get a fish-related joke. These are useful in class, online or for homework; students seem to like them too despite the quality of the jokes…
