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.

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.

Group Challenge Lesson on Area, Volume etc. Students work in groups of 3/4. Collective memory style task to start, then answer questions...submit codes on sheet. Review three times during lesson. Self assessment towards end of lesson whilst you check the scores...plenary..review their self assessment and any questions that proved difficult to answer Top Tip: Freeze your IWB or hide excel as you enter the scores to build the suspense and review progress after each time you mark.

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

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.

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.

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.
