Which Spinners?
This NRICH maths activity is intended for students who are already familiar with sample space diagrams. The interactive file offers an ideal context in which to consider the messy randomness of experimental results and the certainty of the long run results. Working backwards from the graphs should help students notice more features…
Odds and Even
This NRICH maths task offers a good way to reinforce number properties at the same time as encouraging pupils to think about likelihood. It offers an opportunity to explore and discuss two types of probability: experimental and theoretical. The simulation generates lots of experimental data quickly, freeing time to focus on predictions,…
Factors and Multiples Game
This maths game from NRICH can replace standard practice exercises finding factors and multiples. In order to play strategically, students must start to think of numbers in terms of their factors, utilising primes and squares to develop winning moves. There is an interactive resource which allows the students to play against the…

100 Square Jigsaw
This NRICH maths activity can be used as an exploratory tool for children who haven't met the 0 - 99 hundred square before, or it could play a part in assessing their understanding of it, if they have already met it. The problem is a great way for children to reinforce their understanding of the sequences contained within…

Tilted Squares
This NRICH maths activity is an investigation on tilted squares. The aim is to be able to predict the area of any tilted square. In the context of calculating areas by 'boxing in' and/or dissection, this problem offers rich opportunities for systematic investigation which should lead to Pythagoras' Theorem.

Cyclic Quadrilaterals
In this maths problem from NRICH, students will be working with cyclic quadrilaterals. A cyclic quadrilateral is a quadrilateral whose vertices lie on a circle. This maths problem from NRICH is in two parts. The first part consists of four similar challenges which provide building blocks to help you to solve the final challenge.…
Square It
This interactive maths game from NRICH can be played against the computer, or against a friend. It involves completing squares on a grid. It offers an excellent opportunity to practise visualising squares and angles on grids and also encourages students to look at strategies using systematic approaches. Describing strategies to…

Semi-Regular Tessellations
This NRICH maths challenge could prove suitable for students who have learnt how to work out the angles of regular polygons This activity supports the idea that the interior angles of regular polygons are a crucial factor in determining whether the regular polygons will fit together or not. Students are asked to work on paper…
