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!

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.

This was an idea one of my Year 10s gave me using the "Mean Girls" films. This covers basic mean, median and mode before moving on to stem-and-leaf (including IQR) and grouped data - there are three very distinct sections moving up in difficulty to enable you to start/end where you like. It's all on the powerpoint to save the planet (no worksheet) but everything can be copied and pasted to create a worksheet.

This is a set of 6 sheets of increasingly difficult simultaneous equations designed to make students think and discuss how to work through their solutions by giving them different parts of the process. They include simultaneous equations that involve a linear and a non-linear equation. This is also designed to stretch at GCSE or could be used at the start of A level.

Solve the equations correctly to find the quickest path to the exit for our Greek warrior! KS3 / GCSE maths activity with answers.

Two-way tables, filling in the missing information. I needed some questions on this for a lesson and struggled to find what I was looking for so wrote this. Typos now corrected!

Erica is struggling when she has negative and fractional indices to expand using the binomial expansion. Can your class help her out and explain what she's done wrong please? Designed to demonstrate deep understanding and to encourage discussion in class.

I produced this as a class of mine were struggling massively with both topics, and the topics are linked. Designed so that you can just use the multiplying and dividing bit or the metric conversions bit separately.

This is a worksheet with tables using actual data released by the PFA and came from an investigation by the BBC's Football Focus. It's all quite straight forward stuff, but might open student eyes somewhat! Students use he data to calculate percentage changes.

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.

Reveal the Tim Vine joke by finding the fractions of a number. Silly typo corrected too!

The mandatory joke (courtesy of Tim Vine) and various probability questions including simple calculation, expected number of outcomes, the probability of x and y, the probability of "not x".

Erica is struggling with the binomial expansion; can you (and your class) help Erica correct the answers she has arrived at and explain to her what she has done incorrectly. This is designed to create discussion and help students become familiar with new style questions. Actual thing now linked - sorry!

The predictably lame joke upon answering the histogram questions. The first part involves calculating from a frequency table and the second involves reading a histogram.

The mandatory terrible joke revealed by finding some partial fractions. Sheet 2 involves the cover up rule and both involve fractional as well as negative numerators.

This was an idea I had in on the way to work one morning - Clive makes mistakes on his homework and you need to correct them, explaining the mistake he's made in each case. I intend to use this as a plenary or starter to check learning etc. They should create discussion too. There are 5 different mistakes to correct.

There are six spiders to do: two on reading and writing numbers in standard form, two on multiplying and dividing and two on adding and subtracting. Each is designed to be a bit more difficult than the last with some opportunities for discussion.

Clive is getting confused with fractions, fraction of an amount, adding, subtracting, multiplying and dividing. This designed to get students to explain their reasoning and should encourage discussion.

Clive is having more issues, this time with decimals, and a little bit of fractions and percentages. This involves ordering, adding, multiplying, dividing and recurring decimals. Clive needs someone to explain what he’s got wrong. This should encourage students to demonstrate their understanding.

Four matching activities where students can create formulae - they get progressively more difficult. These could be ideal for starters or plenaries and should encourage some discussion. Typos corrected...
