Surds appearing in contexts such as formulae/expressions, area, equations of lines, quadratic expressions, similarity, Pythagoras, trigonometry, speed and density. Enjoy the Erasure album track too…

Ten questions of increasing difficulty (you can choose which you do); four hypothetical students have had a go and one has got the answer correct with the other three making common errors. Not only should your class work out who got it correct but as an extension/part of the activity they could work out the misconception for the wrong answers. This involves lines, polygons, quadrilaterals, circle theorems and bearings.

Find the appropriate equivalent fraction and find the punchline to Tim Vine’s joke; designed as a bit more practice for some of my Year 7 and 8 classes, but could be useful for others. I have uploaded PDF versions so those who don’t have Equation Editor can see them; no need to thank me…

This covers sharing in a given ratio, simplifying and recipes. Each spider has challenges for discussion when seeking solutions. Designed to encourage discussion.

Six trees taking students through simplifying, fractions of an amount, add/subtracting, multiplying/dividing, mixed numbers. Four questions on each getting progressively harder so students can choose the level they start (and finish). Good for starters or plenaries(?).

Eight problems involving angles in parallel lines, probability, averages, area/perimeter, ratio, Venn diagrams, percentage change, arithmetic/geometric sequences where to solve them you can use simultaneous equations. There is a question slide and a solution slide.

Eight situations where forming and solving an equation could be required; topics include Perimeter, angles, averages, percentages, fractions, compound measures, probability and ratio (the final two involve quadratics). Read the instructions and from that form and solve. I have done solutions should you need them.

This not only lists all the topics on the IGCSE maths syllabus but also gives an example of what they all are so you don’t get the continual question “what does this topic mean?”. I put a RAG analysis against each too so that students can focus revision to where it’s required. A few topics added including expanding 3 brackets, transforming functions, an extra indices example, shading regions (I originally left this off by mistake) and adding/subtracting algebraic fractions. I have just added some more examples of transformations and constructions plus summing arithmetic sequences and recurring decimals. Also includes Sparx activity codes (you can delete if you don’t want those). There are now answers (which I have done quite quickly so hopefully not too many errors!).

Four “Show that…” questions involving inequalities; this is more about the method and workings than getting the final answer. This should involve good mathematical discussions.

Four questions, ten possible answers. Students seem to like these and can just get on with them as answers appear on the sheet. This only involves the cosine rule.

The usual joke found by converting times from 12 hour to 24 hour clock and vice versa. Also includes some "worded" times. Designed for starter, plenary, discussion, homework.

Using some (clean!) clips from Monty Python's Quest for the Holy Grail and Life of Brian (5 clips in total) there are some maths questions. Each clip (which has a hyperlink as the embed feature in Powerpoint is messing about) has 3 questions. It was a challenge given to me on Twitter! Should be fun though, and I will have to prevent myself from giggling in the corner. There are Smart Notebook version but the file size exceeds the limit apparently!

This is like Expressions 1 but tougher - involves simplifying with brackets etc. Again I have put two versions: one with my face and one with smileys. A bid to make simplifying expressions more memorable.

Does what it says on the tin frankly.

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

Help J.A.R.V.I.S. with his calculus calculations involving differentiation and integration.

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

Mick owns a printing firm and is doing an audit. His employees like amounts in improper fractions, Mick likes his as mixed numbers. Help both Mick and his employees communicate the amounts of printing equipment they have in stock. Just a quick activity to practice converting...

Calculate how much the catering compnay should order of each ingredient. The recipes are about right (if a little bland) as they are lifted from the BBC website essentially.

KS3 / GCSE questions quiz. This is for use as a team game - choose an Avenger and then choose one of their 3 questions and answer within 1 minute to win 5 points. The quiz is all hyperlinked so just click on the appropriate bit to get to the appropriate slide.
