A 2 page, easily customisable taboo starter / plenary activity. Change the keyword and make the forbidden words as hard or easy as you need to suit the group. 32 cards should be enough!

A task where students can challenge themselves to substitute negative numbers into algebraic expressions - their work is scored according to their complexity, by their colleagues.

A number of activities to consolidate rules when working with directed numbers. A good starter activity to use is an addition pyramid starting with some negative numbers As a plenary I ask the students to tell me where they started and why....

KS3 / GCSE Lesson Plan. A clear powerpoint to explain how to add/subtract fractions. Ideal for first lesson on topic.

A group based recall activity for all major constructions. Read the Smart file for how to run as a lesson.

A set of activity sheets and presentation/lesson for KS3 students to cover the properties of quadrilaterals. Explains line / rotational symmetry, and how/why we mark equal angles, equal and parallel sides. The plenary works as a 'mystery' and checks learning of students by getting them to ask questions that distinguish two shapes from each other.

Useful sheet to get students estimating the roots of integers other than perfect squares, through students knowledge of square numbers.Ask students to work in pairs or small groups. Also works well as a lead in to surds at ks4 *Update* the post it idea below works fantastically well, students can then rank the answers in terms of their closeness to the answer to further reinforce working with decimals.

An initial 3 part lesson to familiarise students with language of circles. Students can then investigate/establish first three circle theorems by drawing/measuring and using what they have learned to solve a few problems. Plenary states the proper names for the theorems and invites students to apply the theorems to further problems.

Circular Task worksheet with a variety of activities for L5 / L6 students to complete, including Writing Expressions Substituting Values Collecting Like Terms General questions about algebra eg...why do we write in alphabetical order. I let students tackle questions in any order then tell me which question was the hardest for them.

Grid style puzzles to assess key skill / revise There are 6 / 8 versions of the same puzzle on each sheet. Tougher problems take out the information in the grid and students have to work backwards to find the missing term or number.

An easy way to try to explain to students why 'minus minus' actually means 'plus'. With thanks for the idea to Craig Barton.

Students have to 'zap' as many aliens as they can by drawing three straight lines and writing their equations. Sheets can either be laminated for multi-use or a purchase of some spaghetti allows students to experiment before they commit pen to paper!

A bingo activity focussing on students knowledge of classifying numbers as square, cubes, multiples, odd / even etc. A fun activity that can generate plenty of discussion, check prior knowledge and provide an opportunity for higher level thinking on the topic.

A complete Revision lesson for putting all those angle facts together, I use this prior to teaching angles in parallel lines. Starter designed to recall previous knowledge, lots of extension opportunities and then a riddle activity for a plenary to reinforce those facts

Three examples of a sheet that I enlarge to A3 to give students general purpose revision on these topics. Most suitable for a lower ability GCSE or any KS3 maths class. The templates can be changed for any topic once youve used them.

A Bundle of Notebook and Powerpoint Presentations introducing ratio, simplifying, unitary form, dividing into a ratio and some basic proportion.

A big value bundle which would form the basis of a 2 or 3 lesson block on this topic. First lesson - why do some decimals terminate and some decimals recur? - getting students to find for themselves through division and investigation that this relates to the prime factors of the denominator. Second / Third lesson - plenty of work / practice including a well graded Mild / Hot / Spicy / Inferno sheet for this tricky topic.

Suitable for KS4 or able KS3 student this is an introduction to probability, with a discussionon the probability scale, through the basics of Tree usage, right upto using a tree for "without replacement" questions. There are opportunities for discussion and extension within the worksheet materials

A two lesson set of notebook files covering finding the exterior and interior angles of regular polygons

A differentiated New Style GCSE lesson on expanding and simplifying expressions, with some work on expanding three binomials.
