Pupils eliminate suspects/weapons/rooms by completing worksheets on a range of algebra topics including substitution, expanding, factorising, linear & quadratic equations, algebraic fractions and simultaneous linear equations. Works well as revision or as a competition. Also includes answers and a worksheet to remind pupils of techniques required.

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).

The first of two complete lessons on distance-time graphs that assumes pupils have done speed calculations before. Examples and activities on calculating speed from a distance-graph and a matching activity adapted from the Mathematics Assessment Project. Printable worksheets and answers included. Please review it if you download as any feedback is appreciated!

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!

Maze consists of squares containing questions (on addition, subtraction, multiplication and division of fractions) with answers, some of which are wrong. Pupils are only allowed to pass through squares containing correct answers. Extension - pupils design their own maze (I like to discuss how they can make their maze harder by including classic misconceptions). Extra worksheet included to help pupils think about misconceptions (warning - this may well confuse weaker pupils!)

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.

Starts as a dice substitution game but goes a lot deeper by considering the expressions as functions and the effect this has on potential strategies for playing the game. Only suitable for able GCSE students - requires a good grasp of quadratic functions. Nice way of revising and exploring the connection between expressions and functions.

A challenging set of puzzles involving equivalent fractions, probably best for high ability secondary groups. Also offers pupils practice of using divisibility tests, simplifying fractions and working systematically. Please review if you like it, or even if you don’t!

A complete lesson (or maybe two) on finding an original amount, given a sale price or the value of something after it has been increased. Looks at both calculator and non-calculator methods. Activities included: Starter: A set of four puzzles where pupils work their way back to 100%, given another percentage. Main: Examples, quick questions for pupils to try and a worksheet on calculator methods for reversing a percentage problem. Examples, quick questions for pupils to try and a worksheet on non- calculator methods for reversing a percentage problem. Both worksheets have been scaffolded to help pupils with this tricky topic. A challenging extension task where pupils form and solve equations involving connected amounts. Plenary: A final question to address the classic misconception for this topic. Printable worksheets and answers included. Please review if you buy as any feedback is appreciated!

A complete lesson on connected ratios, with the 9-1 GCSE in mind. The lesson is focused on problems where, for example, the ratios a:b and b:c are given, and pupils have to find the ratio a:b:c in its simplest form. Assumes pupils have already learned how to generate equivalent ratios and share in a ratio- see my other resources for lessons on these topics. Activities included: Starter: A set of questions to recap equivalent ratios. Main: A brief look at ratios in baking, to give context to the topic. Examples and quick questions for pupils to try. Questions are in the style shown in the cover image. A set of questions for pupils to consolidate. A challenging extension task where pupils combine the techniques learned with sharing in a ratio to solve more complex word problems in context. Plenary: A final puzzle in a different context (area), that could be solved using connected ratios and should stimulate some discussion. Printable worksheets and answers included. Please review if you buy as any feedback is appreciated!

Pupils solve straight forward quadratic equations to reveal a pathetic joke.

Pupils eliminate suspects/weapons/rooms by completing worksheets on a range of fraction, percentage and decimal skills (see separate instructions). Works well as revision or as a competition. Also includes answers and a worksheet to remind pupils of techniques required.

Maze consists of squares containing questions with answers, some of which are wrong. Pupils are only allowed to pass through squares containing correct answers. Extension - pupils design their own maze. I like to discuss how to make the maze harder by including classic misconceptions like divide by 5 to get 5%

Fun quiz where pupils get to run around while still doing maths. Goes down an absolute storm! Can be easily adapted to other topics. See separate instructions.

Classic quiz with questions on area, including parallelograms, triangles, trapezia and composite shapes made with rectangles. Answers on each slide by clicking on orange squares plus 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!

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.

Looks at switching between different bases and the effect of base on arithmetic and divisibility tests.Plus an excel 'base switch&' calculator. A good enrichment task with a historical/real-life aspect, though probably best for more able pupils.

A complete lesson for first teaching what mixed numbers and improper fractions are, and how to switch between the two forms. Activities included: Starter: Some quick questions to test if pupils can find remainders when dividing. Main: Some examples and a worksheet on identifying mixed numbers and improper fractions from a pictorial representation. Examples and quick questions for pupils to try, on how to convert a mixed number into an improper fraction. A set of straight forward questions for pupils to work on, with an extension task for those who finish. Examples and quick questions for pupils to try, on how to simplify an improper fraction. A set of straight forward questions for pupils to work on, with a challenging extension task for those who finish. Plenary: A final question looking at the options when simplifying improper fractions with common factors. Worksheets and answers included. Please review if you buy as any feedback is appreciated!

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

A treasure hunt requiring knowledge of interior and exterior angles. Two sets of questions to dissuade pupils from just following each other! Mistakes on first version now fixed.
