Like a wordsearch but with fractions, decimals and percentages. Students have to find lines which sum to 1.

Students experience division visually through dienes block manipulatives. Learners develop the skill of short division, including understanding of the carrying process. The lesson includes a sheet which can be copied and cut up in case a class set of dienes blocks is unavailable at your school.

This lesson is an introduction to equations by analogy with the balance scale. The animations show what happens when we try to find the mystery weight x, and what to write down in algebra. At the end of the powerpoint is a group activity where students have to solve the equations and spot the pattern in the numbers they find.

This activity invites learners to use calculator skills to find the mean and standard deviation, using statistics students work together to decide on which horse will do the best of 5 races. The powerpoint presentation animates the horse race.

In a series of challenges, students explore the Ulam spiral, finding nth terms of a quadratic sequences. Skills with factorising and proof are developed.

Introduction to Venn Diagrams and set notation using the game “Guess Who?”. Learners follow the clues to eliminate all but one person.

This is a Halloween themed number starter, where students factorise numbers to work out the fangs. This would be an appropriate starter for revising prime factorisation, finding HCF and LCM, or factorising quadratic expressions.

A number puzzle to do with the number of factors of a number. Suitable for a short investigation for KS3 students who have learned about factors and multiples, or a starter for GCSE students learning about the HCF, LCM and prime factorisation.

Students cut out the expressions (hexagons) and the arrows (half hexagons) and find the next expression by following the arrows. This is a special set of expressions and something special happens.

This is a football-themed polygon angles activity. The animated slide shows the ball being passed, the question is at what angle? This would be suitable for a starter or a plenary on the topic of polygon angles, designed to appeal to football fans.

In this activity learners estimate the land area of the British Isles including Ireland, applying knowledge of area formulae for squares, triangles, parallelograms and trapezia. In doing so, students also learn about the modelling process, and how a model can be refined to give a more accurate estimate. The activity would be suitable for the main part of a lesson.

In this lesson, students apply knowledge of surface area of cylinders and spheres to estimate body surface area - the area that the skin covers.
