Four sets of four problems where students have the answer but there are blanks in the questions which require filling in. This is designed to create discussion in class and hopefully provides natural differentiation (stretch the “top end” by finding the general solution where possible compared to finding a single solution). I will be using these as starters or plenaries as I believe they will develop deeper understanding of topics, but feel free to use them as you like (you will as you don’t need me to hold your hand).

This deals with plotting co-ordinates up through gradients and equations of lines, to plotting different types of graph and finally transforming functions.

Clive's made mistakes on his homework again. This time it is on solving quadratics, including the quadratic formula and completing the square in the final two questions. Students need to find Clive's error in each question and involve common mistakes I've seen made in class and in tests/exams. These are designed to assess understanding and to generate discussion.

Calculate how angry The Bulk is by figuring out what scale factor he's enlarged by and using Bulk's 'Angry Scale'. See how that relates to his 'safety' box and its surface area and volume.

This is a word document worksheet involving finding the missing angles using circle theorems for KS4. A colleague of mine gave me this idea of using records and circle theorems - you have to calculate the missing angles to get the turntable fixed in each case. I've chosen some of my favourite albums! A separate answer sheet is included.

Six spiders on surface area and volume (3 of each) and a final "problems" spider. They are of increasing difficulty, moving from cubes and cuboids to prisms to cones, spheres and pyramids. These are designed to avoid students getting into a rut of performing a mathematical recipe by asking a mixture of finding surface area/volume to working backwards. These usually encourage discussion in class.

A simple sheet to match up equivalent fractions, decimals and percentages - colouring in the equivalences in the same colour.

This is a start or end of term activity just to stretch the mathematical hamstrings. Find the punchline to a joke by answering the questions.

Clive is still struggling to get his homework right, this time rearranging formulae being the issue. Your task, or more likely, your students' task (should they choose to accept it) is to check, correct and explain where Clive has gone wrong. Designed to create discussion in class and to check understanding.

Pretty dull worksheet but done for a purpose - it shows two methods of long division.

These are 20 puzzles taken from the popular Nintendo games of the same name. I have chosen 20 more mathematical/logic ones. There are screenshots of each question.

A colleague told me that I didn’t have anything on gradient and so I produced this. The worksheet hopefully leads students from finding a gradient of a line to drawing a line given its gradient to finding the equations of lines and so on. There are 8 sections and a challenge in each section to allow students to prove that they are capable of some quite complex mathematics. It ends with finding the equation of a line given two points on that line but is designed for you to drop in and out at a place of your choosing. Typo corrected!

Clive has two transformation homeworks (the second is more challenging than the first), but as usual he has made mistakes on each of the four questions. The students need to correct Clive's mistakes and explain what he has done wrong. This is designed to create discussion amongst students and with their teacher. The second involves negative and fractional scale factors of enlargements.

Clive's made mistakes on his homework again. This time it is on expanding brackets and factorising expressions. Students need to find Clive's error in each question. These are designed to assess understanding and to generate discussion.

Clive is having a go at some homework regarding speed, density and population density. As usual with these it is a case of spotting Clive's mistakes, correcting then explaining what he has done wrong. They are designed to create discussion points in class.

There are two of Clive's homeworks to check here: one with bar charts, pie charts and frequency diagrams, the second with scatter graphs, cumulative frequency graphs and a histogram. These are designed entirely around discussion both between students and between students and teachers.

A fairly simplistic activity involving calculating the tax bills for various different jobs.

Dr Doom has designed a virus that has infiltrated superhero gadgets and suits. Find the probability of each hero's gadget working. This involves simple probability, expected outcomes, relative frequency and a challenge of mutually exclusive events. It can be done as a discussion activity or as a worksheet where the challenge is on the back.

A little known fact about Santa's helpers the elves is that they are very keen mathematicians. They have written down various bits of information required by Santa in algebra. Help Santa sort it all out. Contains simplifying expressions, solving equations, expanding and factorising and co-ordinates on graphs.

Disarm the bombs by typing in the code that requires Bidmas to find the answers. I admit it, I came up with the name first.
