Human Body

This resource, aimed at primary learners, contains three lessons on skeleton and muscles, digestion and circulation. An interactive simulation, 'Inside the Human Body', explores each of the systems demonstrating their structure and function. It also provides interactive games which support the activities.


Number Stairs

This Subtangent investigation looks at the total of the squares inside a stair shape.

Initially students investigate the relationship of the totals of a three step stair and its position on a 10 by 10 grid.

Using algebra, students may discover a general rule which applies to any stair on the grid....

Loopy Snooker

A special snooker table is the basis for this investigation from Subtangent. There are only four pockets on the table and you can only play the ball at 450 to the sides of the table. The ball begins from a given corner of the table and keeps moving until it hits a pocket. The number of bounces is...


The frogs in this Subtangent investigation have to be moved from one set of lily pads to another, following specific rules. This classic investigation is suitable for a wide age range of students. The number of frogs on each side can be varied, allowing further investigation and generalisations for the number of...

Diagonal Differences

This Subtangent investigation looks at what happens if the numbers in opposite corners of a three by three square, placed on an eight by eight grid, are multiplied then their difference found. Using algebra, students may discover a general rule which applies to any three by three square placed on the grid. Students...

Colouring Maps

This activity from Subtangent is based on the four colour theory, which is used by mapmakers. There is an interactive task which challenges students to colour a map using no more than four colours and ensuring that no two regions which share a border have the same colour. Further resources include examples of...

North Sea Rocks

The resource available consists of the following items:

Circuit Construction Kit

This simulation allows students to build circuits with capacitors, inductors, resistors and AC or DC voltage sources, and investigate current and voltage.

Sample Learning Objectives include: *Build circuits from circuit diagrams. *Use an ammeter and voltmeter to take readings in circuits. *Discuss basic...

Visited Hazelwick School in Crawley- On their open day on careers -on 7 February 2018

Represented Stem  on the above 

Carried out/Talk /Discussions on Engineering as a career for for groups of students.

In all I talked  7 groups of students.. Gave a brief history of my career as an engineer and answered the students' queries and concerns

It was a a whole day affair. 



This Core Maths task investigates various aspects of gambling. Students investigate various aspects of gambling and helps develop a realistic assessment of the risks involved. Students will need a good understanding of theoretical and experimental probability.

Gambling: Teacher guidance...
