Worksheet where answers to questions are used to obtain a 3-digit code (which I set as the combination to a lockable money box containing a prize). Pupils race to finish first and crack the safe.

Maze consists of squares containing identities, some of which are false. Pupils can only pass through squares containing true identities. Identities require ability to expand & factorise quadratic expressions and simplify algebraic fractions, so really only good for a GCSE top set. Extension - pupils find identities of incorrect squares and then design their own maze (there's a good discussion to be had about how to make a good maze - including common misconceptions to fool people).

Based on a few Nrich ideas, pupils use algebra to investigate a number of puzzling results.

A brief look at some of the Maths that underpins cycling performance - how gear ratios, gradient, air resistance and power output effect speed. Requires, ideally, some familiarity with ratios, linear & cubic formulae and functions. Includes some worksheets (at end of presentation) for printing. Nicely timed for the Tour de France. Suggestions for improvement welcome as I wonder if the content is a bit dry!

A set of powerpoints covering all topics in FP1. Examples labelled WB correspond to the separately attached 'Workbook&' (I give this as a single booklet so pupils have a clear model answer to each topic). References to Exercises are from the Pearson Edexcel FP1 textbook.

A set of powerpoints covering all topics in FP2. Examples labelled WB correspond to the separately attached 'Workbook' (I give this as a single booklet so pupils have a clear model answer to each topic). References to Exercises are from the Pearson Edexcel FP2 textbook. Mistakes on complex numbers now corrected.

Based on an Nrich activity, pupils investigate how many different triangles can be drawn (with some restrictions). Leads to a very nice visual result and discussions about how pupils know they have found all possible answers.

My take on Daniel Burke's excellent idea of odd-one-out set to a song featuring Cookie Monster. The box at the bottom of the puzzles should show the video but Powerpoint and the TES website don't like this link, so I&'ve given the website address to download the video, which you can then insert into the powerpoint. Menus are clickable (clicking on the top heading will take you back to the previous menu). Correct answer flashes after 50 seconds (this coincides with the video)

Inspired by something similar I saw on Don Steward's Median blog, a set of non-calculator questions that reward pupils for applying the basic index laws before trying to work out the answer.

A complete lesson on subtracting a negative number. Activities included: Starter: Some recap questions on adding a negative number (I always teach this first). Main: A slide showing a number pattern to demonstrate the logic of subtracting a negative. Example question pairs with number lines, for pupils to practice and give a chance to provide instant feedback. A set of differentiated questions. A more challenging task for pupils to discuss in pairs, where they try to find examples or counterexamples for different scenarios. Plenary: A deceptively simple puzzle to consolidate the key point of the lesson. Printable worksheets and answers included. Please review it if you buy as any feedback is appreciated!

Example question pairs with number lines, for pupils to practice and give a chance to provide instant feedback. A set of differentiated questions. A more challenging task for pupils to discuss in pairs, where they try to find examples or counterexamples for different scenarios. Plenary: A final question to prompt discussion about misconceptions pupils may already have. Printable worksheets and answers included. Please review it if you buy as any feedback is appreciated!

An excel file that shows pi as the ratio of circumference / diameter for a circle

Classic quiz with questions on linear equations, including unknowns on both sides, brackets and simple algebraic fractions. Answers on each slide by clicking on orange squares. Hope no-one minds my use of an image of Bob Holness - he will always be the face of Blockbusters to me!

Hard to describe! Shows how the functions sin and cos effect the trajectory of a cricket ball. A nice real-life example of SOHCAHTOA and the trigonometric functions. Includes some challenging questions at the end. Could be used to revise/demonstrate the curves of sin and cos at GCSE or introduce component form in A-Level Mechanics.

A very simple but motivating game where pupils race to complete a grid of times tables. Separate instructions attached. Also a spreadsheet which reveals answers and can be used to keep track of pupil progress (I maintain records of pupils' personal bests on there). A good task for settling a class that requires minimal preparation.

Classic quiz with question on angle rules, including simple parallel lines and knowledge of shape properties. Answers on last slide. Hope no-one minds my use of an image of Bob Holness - he will always be the face of Blockbusters to me!

A simple but adaptable interactive picture quiz in powerpoint to dress up asking questions - ideal for starters or plenaries. Think Catchphrase but with 2 different images for 2 teams and pictures of anything you fancy. You provide the questions. See separate instructions.

Based on the card game, pupils use their percentage and fibbing skills to win.

A GSP file (requires Geometer's Sketchpad software to open) which measures, for a right-angled triangle, the sides and ratios sin, cos and tan. The triangle can be changed dynamically. Also shows the graphs of the ratios. Could be used to introduce trigonometric ratios, explain the graphs of sine, cosine and tangent up to 90 degrees or to generate questions on SOHCAHTOA.

Worksheet where answers to questions are used to obtain a 3-digit code (which I set as the combination to a lockable money box containing a prize). Questions on all aspects of parametric functions as seen in C4
