As many of my students struggle with number facts and recalling what they mean I thought I'd do this as a bank of starters/plenaries. Nothing to print, just display on the board.

This activity uses clues involving number facts and special numbers to find certain items in a supermarket. Some of the clues are easier than others, but it's a nice challenge and makes students aware of Fibonacci, square, cube and triangle numbers.

Three different activities, each with five questions and a choice of three answers. They must scan the QR code associated to the correct answer to get the next 'colour' in the code. Activity 1 is wordy but relatively easy, Activity 2 a little tougher and Activity 3 that hardest (including factorising quadratics).

I was doing some revision with a class and realised that I was yet to do a sheet involving HCF and LCM and everything along those lines. That is now remedied.

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.

Erica has homework again but is getting a little confused. She needs your help to explain where she has got confused and to correct what she's done. These questions contain common mistakes and should lead to discussion in class between students.

Laura Craft, our hero, has slides to go down this time ot complete the game that are in the shape of cubic graphs. we have the equations but not the graphs (you need to draw them) and work out which is the steepest - could you tell from the equations?

Four problems for students to correct for Clive; he has made some common errors on his homework again. This is designed to get the students and teacher discussing probability. Small typo amended.

This is an activity taking students through nth terms of arithmetic sequences, summing arithmetic sequences and nth terms of quadratic sequences. Different pieces of information are given each time to ensure that students develop understanding rather than get in a rut and performing a process. This should lead to discussion in class between students and teacher.

Erica is struggling with iteration and Newton-Raphson, as it's on the new "Pure 2" syllabus. Can you help her sort out her homework answers and explain what she's done wrong?

The “Building Blocks” sequel to “Percentage of an Amount” - this goes through percentage change of all types.

Calculate how much food my pets are going to need whilst I'm away on holiday for a week. This involves multiplying, dividing and adding fractions.

This covers pictograms, bar charts and dual bar charts. It is just a simple set of 4 queestions, nothing more than it says on the tin.

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!

Answer the questions, reveal the punchline; this old chestnut once again! It includes ascending and descending sequences.

A task based on card shuffling from QI from a video posted on Twitter by @bobloch. What possible order could the cards be in in each case?

Erica is struggling with integrating e^x, is getting confused between integrating 1/(x) and 1/(x^2) and basic trigonometric integration. Can someone help her out? This is designed to help students discussion and prove their understanding.

Calculate how many heads the Hydra will have after a certain amount of cuts by Hercules. The Powerpoint now contains the video.

I now teach enlargements using the vector method and decided to produce a worksheet to encourage this method, which involves fractional and negative scale factors.

This was an idea I had in a bid to get the students to explain their thinking mathematically. Error corrected!
