There are four spiders (the last one has lost a couple of legs, I realise that!) of increasing difficulty. Fill in the blanks by using skills of adding and subtracting fractions. The final "spider" is a discussion one with many answers and the chance for students to fully demonstrate their understanding.

Four lots of 4 average and range problems where the students are given the answer but need to find the blanks in the question. Some have one possible solution and some have many solutions which automatically builds in differentiation as you could task students with finding the range of possible solutions. I use these as starters/plenaries but use them however you like (assuming you like them).

This involves the old water issue, requiring 4 litres when you only have containers of 3 litres and 5 litres, plus an interactive game from subtangent.com. I have done a powerpoint version exported from SmartBoard too, on request, and now I have worked out how to embed the video! Enjoy!

Matthew the Mathematician has wants a house designed mathematically - this involves transformations, calculations, properties of number etc.

Is Blitzen correct in telling Santa what the equation of his flight path is? It's up to you (or your class) to show that it is!

This worksheet has six questions and eight answers to choose from (this is to avoid students guessing the final answer/answers) so that Santa can rest two reindeer for each trip. This one covers parallel and perpendicular lines and contains an answer sheet. I use these as starters/plenaries or as "prove you can do this topic" sheets. I have used them as quick homework tasks too.

Taking students through the skills required to solve problems involving surds. There are questions that students will need to do without a calculator as the calculator will give them the fully simplified solution.

Two codebreakers: one of frequency tables and one with grouped frequency. The usual; you know how these work by now… Typo corrected…

Three sheets; one each on reflection, rotation and translation. Each one leads to a lame joke as usual.

The aim of this is as a starter or plenary but could be used as a class activity. This activity is designed to get students thinking and discussing properties of number. The aim is to allow students to show what they do/don't know and understand. I have two versions: one where students find the number given the properties and vice versa which I suspect will create more discussion. There will be extra properties I've left out on purpose. There is a blank to make up your own too.

This is designed to encourage students to explain their working rather than just read out an answer at the end. I have given an example of solutions but these are not the only solutions for each. This should encourage discussion too.

Use the information to cost the building of a swimming pool. I have tried to use genuine values for costs of hire and labour, so the the results should be fairly accurate.

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

Answer the questions and reveal the gag; I rather like this joke (I saw it on social media and it’s clean). There are “given that…” questions too to create discussion.

Calculate how much of the wall can be covered by Willis and Granite's new invention and draw your own conclusions! Involves area, percentages and as a result proportion.

This worksheet cover negative quadratic graphs. The curves are drawn and students must find the equations using the roots. They can then solve simultaneous equations using their graphs, both y = a number and y= mx+c and we finish off with some differentiation and calculating of gradients and normals. There are 4 parts to this so you can stop or start at the appropriate level for your class.

Four screens each with four questions that have the same answer but the question is missing information; can your class work out what information is missing? This is designed to create discussion (some questions have multiple answers possible) and I intend to use these as starters. Topics include gradient, equations of lines, probability, solving equations, indices and many more.

Worded pie chart questions with a terrible joke to unravel; my Year 7s enjoyed it as a starter…

Answer the questions involving density, mass and volume to reveal the punchline to a joke. These work well as either class activities, online school activities of as a homework and students seems to like the challenge and competition to find the punchline first.

Cut out the cards and the students use the clues to guess each shape.
