Defuse The Bomb - Simultaneous Equations (Linear)

Defuse The Bomb - Simultaneous Equations (Linear)

(0)
Three sets of questions where the answers appear on the sheet as well; this allows for the students who are understanding the topic to know that they are because their answers are on the sheet already, leaving the teacher to help those who need it. There are 3 sheets in total of increasing difficulty. I tend to use these at the start of a topic or a starter before moving on to the next stage.

Defuse the Bomb - Surds

(0)
Five worksheets with fewer questions than answers given allowing students to start and be reassured if their answer appears in the list of potential solutions allowing teacher to help those who really need it. The sheets get increasingly challenging from simplifying, basic rationalising, calculating, expanding brackets and rationalising “full on”!
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.
Expanding and Factorising Quadratics - Fill In The Blanks
alutwychealutwyche

Expanding and Factorising Quadratics - Fill In The Blanks

(0)
This resource uses tables when expanding and factorising but you can edit if you want to do something else. Essentially this leads students through forwards and backwards through expanding and factorising two brackets, and should lead to discussion. There is an extension where a is not 1.
Cosine Rule - Fill In The Blanks
alutwychealutwyche

Cosine Rule - Fill In The Blanks

(0)
Two sets of questions (one on calculating a side, one on calculating an angle) using the cosine rule, allowing students to place measurements in the formula and work backwards from formula to diagram. This is intended for use when introducing the formula to students but you know your students better than me so use it (or don’t) however you like.
Erica's Errors On Correlation

Erica's Errors On Correlation

(0)
Just two questions on correlation and a bonus question on measures of location involving bounds, but Erica is still having a bit of a nightmare! Can your students explain where Erica has gone wrong so that she doesn’t make the same mistake again?
Equations of Linear Functions Codebreaker

Equations of Linear Functions Codebreaker

Essentially students must use y=mx+c to answer questions then reveal the punchline to a joke. There is a grid and five lines from which to refer to, but this includes parallel and perpendicular lines and their equations as well.
Defuse The Bomb - Inequalities (Quadratic)
alutwychealutwyche

Defuse The Bomb - Inequalities (Quadratic)

(0)
Solve the quadratic inequalities to work out the order in which to cut the wires. I find these sheets useful as the answers appear on the sheet and therefore students can check quickly (without asking the teacher) whether they are on the right track; this means that the teacher can help those who genuinely require it.
Circle Theorems (Geometric Proof) Codebreaker

Circle Theorems (Geometric Proof) Codebreaker

(0)
Find an expression in terms of x for y using circle theorems and discover the punchline to a cheesy joke. Designed for AQA Further Maths Level 2 Certificate but could be used as an extension at GCSE. Typo corrected!

Careless Casey - Geometry I

(0)
Casey is doing the AQA Further Maths Level 2 Certificate but keeps making mistakes; can your class help Casey and explain what went wrong? This time Casey is tackling circle theorems, trigonometric identities, trigonometric equations and surds (trigonometry in right-angled triangles). Spot the mistakes…
Show that... Adding and Subtracting Fractions

Show that... Adding and Subtracting Fractions

(0)
This is designed to encourage workings; students are given a correct addition or subtraction of fractions and have to fill in the blanks in th workings. I have included a “possible workings” files as well, but I don’t really want to force students down any specific road, only encourage them to get each stage down on paper.
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 - Solving Quadratics (Algebraic Fractions)
alutwychealutwyche

Defuse The Bomb - Solving Quadratics (Algebraic Fractions)

(0)
Six questions, ten possible answers for students to have a go at. These have worked well on lockdown as those who feel confident can get without having to to ask the teacher to check their answers. The extra answers mean that students can’t guess or at least find it more difficult!
Defuse The Bomb - Circle Theorems (True or False) 2
alutwychealutwyche

Defuse The Bomb - Circle Theorems (True or False) 2

(0)
It’s the explanations of how answers were arrived at that I find students struggle the most with so hopefully this sheet helps with that. I have found these resources really encourage discussion in class and some relatively deep mathematical thought.
Defuse The Bomb - Bounds
alutwychealutwyche

Defuse The Bomb - Bounds

(0)
Three sheets on error intervals and bounds (including calculations). There are six questions but ten possible answers to choose from so students can’t guess but can check if their answer is correct.
Impossible Maths - Geometry
alutwychealutwyche

Impossible Maths - Geometry

(0)
Based on the daytime gameshow where one question has three options: one correct, one incorrect but correct in a different context, one impossible (wrong). This is designed to test students’ knowledge then their reasoning to find which are the incorrect and impossible answers and why. Topics include: area, angles (parallel lines and polygons), circle theorems, vectors, transformations and more. There are 12 questions…
Impossible Maths - Algebra
alutwychealutwyche

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.
