A comment from my trainee teacher made me think that rounding to decimal places and significant figures needed an activity, so I came up with this. It should get students thinking and should open up discussion on rounding, which can be a little "dry" but essential to get to grips with. Typo corrected!

Four spiders, two with curve and two involving trigonometric functions. These are designed to be used as starters or plenaries but they also work as consolidation activities.

My daughter won this in a Christmas cracker (she was over the moon!) but it is full of sequences and I thought it would make a nice little activity for a class or two of mine.

I just wanted a reasonably simple reflection worksheet for some lower ability students so came up with this and it seemed to challenge them.

I've recently discovered this in my folders on my computer. It is a 10 question non-calculator quiz using real situations.

This was designed as a "taster" session to A Level mathematics for Year10s/11s and builds on what they should know regarding expanding brackets until they discover that you can use Pascal's Triangle to expand brackets. It gives them the chance to investigate their theories and what effect a negative sign makes.

This is designed to get students to think about algebra and substitution as well as knowing properties of number. This is looking at what you can substitute into an expression or a formula (so that rearranging is involved) to produce a given property. This is intended to create discussion and each question has multiple answers, some of which could be generalised therefore creating extra challenge for those who require it.

This presentation just takes you through definite integrals and uses questions from Edexcel; please don't expect anything flashy. If the animations get mixed up I apologise but for some reason Equation Editor doesn't have square brackets onto which one can put limits! Annoying.

These spiders (there are seven of them in total) take you through simplifying, calculating, rationalising denominators, expanding brackets and rationalising "tough" surds.

This should bring about plenty of discussion. Four "spiders" of increasing difficulty asking students to complete a list of numbers to make the average and range properties true. A couple of typos corrected.

I did this having seen numerous poor attempts at sketches in books on recognising types of graph.

Four sheets (two with mixed numbers, two without) to practise multiplying and dividing fractions. This is just a different way of doing some questions and depending on how it's run can involve plenty of discussion.

This moves through fairly easy to expanding two brackets via 8 different matching activities. This should give students the opportunity to discuss their thoughts and demonstrate their understanding.

Six matchings involving set notation and shading Venn diagrams. Hopefully these will encourage discussion in the classroom and they are designed as starters or plenaries where students, since most of the answers are there, are encouraged to try harder problems than they might normally do.

All the skills required for sequences up to and including summing arithmetic sequences and geometric sequences.

This (hopefully) covers circle theorems from basic up to one proof questions using circle theorems. There should be enough variety to cover all bases.

This leads students through graphing trigonometric functions, transforming f(x) and transforming a trigonometric function. The graphs are as big as I can make them in the format given so sorry if they are a bit small. I used Desmos for the graphs if you are interested (it’s brilliant!).

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.

From drawing the next pattern to finding the nth term of an arithmetic sequence. Enjoy!

Geometry worksheet activity: Cut out the facts on triangles and quadrilaterals and put them in to groups: Always True; Sometimes True; Never True.
