Eight matching activities that encourage discussion in class involving substituting into functions, inverses and composite functions. These would work as a starter/plenary or as a revision lesson on function notation.

This takes students through factorising quadratics, solving them and onto completing the square, including solving quadratics that won't factorise nicely. Designed as starters/plenaries/assess the learning activities.

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 twelve transformations here, all of which have more than one solution; this asks students to find as many solutions that work, including reflections, translations, rotations and enlargements with negative scale factors. I did this with a class and offered rewards for any solutions I hadn’t listed which seemed to motivate them even more! Solutions are on a separate slide to enable printing.

Given one coordinate, can students come up with a second coordinate so that the line between the two meets certain criteria? This is an activity designed to create discussion, covering gradient and equations of lines. Extension should be pretty easy, allowing students to generate equations of lines etc. I have left a slide template so that you can create your own if you wish.

This is a presentation involving six real recipes (linked on each slide) and their ingredients which students have to work with to make the number of each required. This is designed to create a bit of discussion and the questions get more challenging as you work through them.

Each slide contains five questions that have been answered, but not necessarily correctly. Your class need to discuss whether the answer given is correct or not and find the correct answer if not. These bring up common errors and lots of discussions. Areas covered: substitution, inverses, composite, domain & range.

I got shown this by a colleague so thought I would PowerPoint it; there are essentially a few versions of the same thing: Minimally labelled etc - for a strong set of mathematicians All angles marked The side or angle you need to find next is highlighted I will use this to introduce the addition formulae. There may well be other/better versions out there so I am sorry if I have wasted your time.

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

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.

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

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...

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?

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.

I found a graphic on Twitter and thought it would make a nice discussion lesson/part lesson on time and number, possibly standard form. Anyway, I made this Powerpoint to get people started.
