Full lesson on data collection (used for an observation) comprising: starter to be discussed on what makes a good survey question and collection method, collection worksheet (to be circulated) for groups to decide on their question and how to collect the data, and peer-assessment form for adjacent groups to mark work.

Match-up task drawing lines between conditional probabilities and answers. Best for use under a visualiser.

Match-up task drawing lines between surds and their simplification. Best for use under a visualiser.

Match-up task determining the procedure for solving problems using SOHCAHTOA. Best for use under a visualiser.

Lesson starter on sine and cosine rule recapping which formulae are applicable to a given triangle. Best for use under a visualiser.

Detailed lesson starter on sectors and segments, including labelling circles and calculating areas. Best for use under a visualiser.

Match-up task drawing lines between sampling types in A level maths and their descriptions. Great for revision.

An extension lesson which introduces basic group theory (without the formalisation) applied to symmetries of a square. Cut-outs provided: students should stick pairs of squares back-to-back so that the numbers line up on either side. Answers to the worksheet also provided.

Worksheet that guides students through the derivation of the sine and cosine rules. Answers provided.

Advanced worksheet on areas of sectors and segments of circles, which finishes with difficult questions using MacClaurin series to answer a couple interesting questions!

An investigation on finding circumference and areas of circles with cutout circles to measure.

Lesson starter for a review lesson on Pythagoras’ Theorem. Includes addressing misconceptions and the area proof as a mini-extension. Good for use under a visualiser in front of the class.

Starts off with basic (but creatively written!) compound interest questions, before moving on to some difficult multi-step questions on percentages. Answers provided.

Extension on transformations that works with reflections algebraically. Answers provided.

Extension on Sample Space Diagrams that generalises the class “sum of two spinners” setup to spinners with n numbers on each. Answers provided.

Extension that works with linear and quadratic sequences, finishing with using quadratic sequences to find expressions for sums of positive integers. Answers provided.

An extension on Pythagoras’ theorem, including multi-step problems. Answers provided.

A hedgehog-themed worksheet on problem-solving with averages from frequency tables. Answers provided.

Simple series of questions (perhaps for a quick homework) that gets students to sketch shapes of further graphs. Answers provided.

A good powerpoint to show a Year 11 class near their GCSEs on how not to lose silly marks by e.g. forgetting how to draw a frequency polygon or stem-leaf-diagram, how to estimate the mean from a grouped frequency table etc. Aimed around Grade 4/5 topics, so should be suitable for both foundation and higher sets.
