The computers are down and people want to check out so their bills need ot be calculated manually. There's an extension that involves taking off a given amount in tokens.

Nothing particularly enlightening here other than I found that using function machines to show how to calculate a dimension given the area formula seemed to work quite nicely with a class of mine. This should be a discussion activity in my view.

Powers calculations to get correct so that the student can defuse the bomb successfully. This is based upon squares and cubes but ventures into other powers of 2 and 10.

Read this piece of news item from the BBC Sport website, then answer the questions, mainly about percentage change.

Casey is doing the AQA Further Maths Level 2 Certificate but keeps making mistakes; can your class help Casey and explain what went wrong? This time Casey is tackling circle theorems, trigonometric identities, trigonometric equations and surds (trigonometry in right-angled triangles). Spot the mistakes…

Casey’s tackling quadratic sequences, quadratic inequalities, factorising cubics using the factor theorem and solving quadratics “in disguise” but making errors again and need your class’ help. Ideal for discussion in class… Designed for use in the AQA Further Maths Level 2 Certificate course.

Casey is making mistakes in the AQA Further Maths Level 2 Certificate chapter on Coordinate Geometry, involving gradients, circles (equations), dividing lines in a ratio; can your class help Casey out? This works nicely in class and gets students discussing mathematics. Typo corrected…

Four of Clive’s “homework” sheets to correct and explain where he’s gone wrong. There are four to complete: a “basic” one, one on parallel lines, one on polygons and finally one on circle theorems. The basic and parallel lines ones have 5 questions to correct; the other two have 4 questions to look at. These are designed to encourage discussion between students and then to share that discussion with the teacher as there’s not always one way to correct a question. I introduced these before the holidays and they went very well.

Casey is at it again whilst going through the AQA Further Maths Level 2 Certificate course. Algebra III is essentially functions so this includeds domain/range, equations of functions given two points, composite functions, functions split in to three distinct parts. The usual correct and explain stuff which encourages discussion in class.

Casey is making mistakes again, this time involving difference of two square, rearranging formulae, algebraic fractions and completing the square where the coefficient of x squared is not 1 (and is negative). The aim is to get classes discussing methods and deepening understanding and is aimed at the AQA Further Maths Level 2 Certificate course (Chapter 2).

This is a twist on revision notes. I have written some notes and given examples but there are mistakes that the students have to correct. They must therefore read the notes very carefully and a partner must check their work. The idea is derived from an idea born from a discussion on Twitter (if you're not on Twitter, seriously think about it). I have split the notes up into three but I have included the whole thing so that you can chop them up your own way, or change stuff if you want. It&'s a bit of an experiment and we&';ll see how it goes!

This is an activity where you have to calculate missing sides and angles for computer software designers, based upon Link's Crossbow Training on the Wii! There is an extension where they have to produce general formulae where there are different ways of calculating the same thing depending on what you are given.

This is a powerpoint covering all aspects of sets and venn diagrams required for GCSE. It contains brief notes by way of an explanation, model answers to questions and a question or two for the students to do; all of the questions come with answers that you can display when ready. The slide show comes with a progress grid (regularly referred to in the presentation) so that students can mark their progress from start to finish and pinpoint any areas that may need extra work with a “red/amber/green” system that they fill in; each one is given an approximate grade in both new (2017 onwards) and old system in England. It’s what I use in my lessons before setting tasks from worksheets or text books to practise.

This is a powerpoint covering probability from basic single events to tree diagrams of dependent events. It contains brief notes by way of an explanation, model answers to questions and a question or two for the students to do; all of the questions come with answers that you can display when ready.

Given the equations of the curves required to destroy the pigs, can the students plot the graphs? This is an attempt to bring quadratic graphs to the world of the teenager!

This is a powerpoint covering inequalities from number lines, solving and shading regions. It contains brief notes by way of an explanation, model answers to questions and a question or two for the students to do; all of the questions come with answers that you can display when ready.

Help desperate Food Tech teacher Billy Black with his cake recipes before he's abducted by aliens. Clearly a play on the TV show, but an exercise in simple proportion using amounts of ingredients for recipes - the calculations get progressively more difficult.

These are all available individually for free but are available as one big bunch here. The concept is to choose the correct order to cut the wires by answering the questions correctly - each wire is linked to a question. Not all the wires need cutting to prevent guessing at the end. I use these as starters, plenaries (prove you can do the work tasks) and quick homeworks!

The bosses at Legoland are building a new scale model of the UK and need your help with the scales. Basically fill in the blanks.
