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 came about after a colleague of mine (a Spurs fan) was moaning about a VAR decision that prevented Spurs from winning a Champions League match. Another colleague (a Brighton fan this time) suggested we check the errors in measurement and this was born. It is a bit of an experiment and I am aware that error is built in to the systems but I thought it was a nice practical use of something we cover in GCSE Maths. There are four scenarios: one tennis, two cricket and one football; questions are quite wordy but need to be to explain the laws of the sports in question.

Tutorial with questions taking you through primes, multiples, writing and reading numbers, directed numbers (negative numbers), prime factors, HCF and LCM.

This takes students through factors, multiples and on to HCF and LCM. Hopefully this will allow students to work out what HCF is themselves.

A student gave me the title (pun on 'The Hunger Games' - original was 'The Number Games'), I did the rest. Five different sets of questions in a functional style for students to work through either individually or in pairs/teams.

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!

With the new curriculum in mind I did this. Students must use their knowledge of parallel and perpendicular lines to fill in blanks but this could lead to discussions about different ways to write equations of lines etc. Errant negative signs on number 4 corrected (I hope).

There are eight matchings here: 4 surface area and 4 volume. They get increasingly difficult moving through cubes/cuboids to prisms to cones, cylinders, pyramids and spheres. These are designed to be used as starters or plenaries but you can use them for a lesson main activity, totally up to you.

This idea is from Craig Barton and is an excellent one (check them out his at website); essentially it is four questions based on the same information. There are four here which use perimeter, area, Pythagoras, equations of lines, coordinates, vectors, equations of circles, expanding brackets, solving equations as well as other topics. This really should create discussion and a deeper understanding of the topics covered on top of ensuring that students actually read the question. I hope these are worthy! I will be using these as starters or plenaries.

The students are given the answer and asked to fill in the gaps in the question. Topics used involve probability, algebra, fractions, percentages, ratio, speed, distance, time and many others. Some of the questions allow for multiple answers so discussion could be had. Designed to be used as starters/plenaries to get the grey matter moving. The Easter theme runs through every question and is a tad tenuous at times but there you go.

Work your way up to 3D Pythagoras and trigonometry…

A series of real-life graphs that are misleading in some way. Nice for a discussion activity.

This covers adding and subtracting vectors and multiples of vectors before moving on to describing journeys using vectors. This is essentially a load of questions on vectors but they should encourage discussion in class. Typo corrected

Surds practice from basic simplifying to expanding brackets to rationalising denominators. This encourages workings and the students to work backwards (what's the question given this answer?) so should also encourage discussion in class.

This is a different way to allow students to gain some practice in short bursts and helps introduce fractional indices. The point is to generate discussion in class whilst the students do some work.

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.

I just wanted something that covers bar graph; this covers “normal”, comparative and composite bar graphs and is designed, in two cases at least, to create discussion.

Taking students all the way from pictograms, through bar charts, pie charts, stem-and-leaf, scatter graphs, frequency diagrams, cumulative frequency, box plots and histograms. The graphs are as large as I can make them and should be ok if copied on to A4.

There are 8 sets of five questions that have been answered either correctly or incorrectly, the students have to decide which. These are designed to create discussion in classrooms and include one-step, two-step, brackets, variables on both sides, equations involving fractions, simultaneous equations (linear only) and quadratic equations (both factorised and non-factorised). Hopefully there should be something for all levels up to GCSE.

Six slides each containing five questions where students need to decide if the answer given is correct and explain how they have arrived at their conclusion. Topics include whether a coordinate lies on a line given its equation, y=mx+c, equations of curves (quadratics, cubics, reciprocals), gradient, These are designed to generate discussion in class.
