This lesson develops the concept of making sense of the standard algorithms for addition, subtraction, multiplication, and division of positive integers. In particular students will work on the following areas:

• Improving conceptual understanding of why and how the algorithms work.
• Developing...

This resource from TechSheCan explores how technology is used to keep us safe online. It references cyber-attacks, facial recognition, hacking home devices and password protection. It includes lesson slides, teacher notes and a homework activity.

Carom Maths provides this resource for teachers and students of A Level mathematics.

There are six ways to write the total edge length, total surface area and volume of a cube, or cuboid, in order of size. This presentation challenges students to find a cube for each order. Autograph files are provided to...

In this activity, learners will use a vacuum former to manufacture a suitable casing for a programmable product. It...

This activity away from the computer is from the Barefoot Computing project. It is intended to provide a theoretical understanding of why and how variables are used in computer programming, using the example of score-keeping in a classroom quiz. Involving several volunteers from the group, the activity uses...

This interactive resource, produced by the University of Leicester, is designed to enable students to explore vectors, beginning with the definition of a vector followed by the algebra of vectors and the scalar product. The opening slides of the presentation explain the difference between scalar and vector...

This paired-programming activity from the Barefoot Computing project focusses on sequences in algorithms and programs.

Children create an animation of a Viking raid – ideally they will have previously studied Vikings...

Recent headlines point out a 400 % rise in rickets and other bone diseases as young people spend more and more time indoors. Recent UK health guidance recommends that everyone should consider taking a daily vitamin D supplement, particularly in autumn and winter. In this activity students make a personal decision...

This activity shows how Earth observation can be used to study human geography by comparing the satellite images of Las Vegas over the last few decades. Linking to measurement of irregular areas and addition and multiplication of fractions, it asks children to measure the area of Las Vegas at three separate times...

This resource explores what volcanoes are and some of their key features. Students will learn why volcanoes erupt and the difference between effusive and explosive eruptions as well as understanding the effects magma viscosity can have on lava flows and eruptions by conducting experiments to test the impact of...

In this resource pupils will learn that volcanoes are openings in the Earth’s rocky surface and can be active, dormant or extinct. They will learn about the structure of a volcano, how volcanoes form and different types of eruption then create their own erupting volcano using washing-up liquid, bicarbonate of soda...

The coordinates of the vertices of a tetrahedron is given. The challenge is to work out the volume of the tetrahedron. This involves calculating the area of the base,...

This activity comes with a handy teacher's guide and lesson plan, a set of easy to read questions aimed at probing deeper thinking in your pupils, and an informative presentation to run the activity. Learn how water is able to walk between glasses, using an absorbent bridge. Teach about water transport in plants,...

Carom Maths provides this resource for teachers and students of A Level mathematics.

Wallpaper patterns all have one thing in common; they are all produced by repeating a single fundamental tile by translation, that one basic rule gives rise to a range of possible patterns, each with their distinctive...

This brief activity uses false-colour images of the Columbia glacier to introduce the idea of using sequences of satellite images to monitor change and focuses on the selection of appropriate data for an investigation.
