Pythagoras and Trigonometry Codbreakers

(0)
Two fish jokes to reveal: one is trigonometry in right-angled triangles and one is either Pythagoras or trigonometry. These are always popular with my classes and I’ve used them in class and online but I know colleagues have used them as homeworks.

Going To The Sales

(1)
There are six slides with a percentage and fraction sales-related question question. This involves calculating sale prices, working out which sale would offer the best price and finding the original price given the sale price. This is designed to create discussion in class.

Surface Area (Cubes and Cuboids) Codbreaker

(2)
Answer the questions on surface area of cubes and cuboids and reveal the punchline to a fish joke. These work well in class, online or as a homework and offer some reassurance as students find their answers in the table allowing the teacher to help those who really need it.

Defuse The Bomb - Surface Area (Cubes and Cuboids)

(0)
I am going to be teaching Year 7 some surface area of cuboids and cubes but only had one of these involving prisms which might be a step too far at this point. This was what I came up with. The answers are on the sheet (although there are more answers than questions to avoid default answers at the end) which gives students the confidence to keep going if they are getting questions correct allowing the teacher to help those who really need it.
Defuse The Bomb - Tree Diagrams
alutwychealutwyche

Defuse The Bomb - Tree Diagrams

(1)
Students must work out whether statement is true or false regarding the tree diagram. These sheets work well online in my experience as they can be done from the screen. This involves a tree diagram where the second probability is conditional upon the first.
Defuse The Bomb - HCF and LCM (including Prime Factors)
alutwychealutwyche

Defuse The Bomb - HCF and LCM (including Prime Factors)

(1)
This is a sheet which involves eight questions with answers given on the sheet (there are ten potential answers for the eight questions to avoid guessing). These have worked well for online schooling and allow students who are reasonably confident to get on as their answers appear on the sheet. In the meantime the teacher can help those who are less confident.
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)

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
alutwychealutwyche

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.

There are 28 Defuse The Bomb worksheets here, each with answers.

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

(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.

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

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.
