This puzzle provides an introduction to simultaneous equations in three variables. Three combinations of coins are shown, together with the total value for each pair. The challenge is to calculate the value of each coin.

This task is designed to assess how well students understand various aspects of the number system.

There are a series of short tasks on using a calculator, working with fractions, directed numbers, and extending a multiplication fact.

With just one fold of a square piece of paper, is it possible to make a triangle and a quadrilateral? Two quadrilaterals? A triangle and a pentagon? A further challenge asks students to explore the combination of shapes that can be made by using two folds of a square.

This is a nice example of an animation produced by students to explain one impact of climate change - ocean acidification.  You could link with a local university department to enrich a project like this, as has been done in this case - Ridgeway School in Plymouth ...

This lesson plan and classroom presentation explores some of the skills and knowledge needed to work in the field of biomechanical engineering. Combining knowledge from Biology, Design and Technology and Engineering, it asks students to investigate the design and development of a prosthetic arm.

In this lesson students will gain an understanding of timber seasoning (both naturally and artificially) to help reduce the moisture content. They will develop an understanding of the process of converting a log into lumber and timber conversion through video clips and diagrams. Exam style questions are included to...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe what a light ray represents
• Describe the direction in which light travels from a light source
• Describe how light rays are emitted from each point on an extended...

This puzzle provides a gentle introduction to simultaneous equations. Three pictures are given that show different combinations of three items from a menu, together with the total price for each meal. The challenge is to work out the cost of each item.

A statistical graphic from the Gatsby Foundation which demonstrates the chronic shortage of physics teachers across the UK and which looks at the various campaigns to address this shortfall over the past few years.

This problem looks at fencing chickens using pens. The challenge is to work out how many lengths are needed to create six separate pens for the roosters.

This combination problem builds up from combinations of three socks to six socks. Can students find a pattern and use it to work out how many socks would be needed to ensure a different pair was available each day for a month?

Hold a ruler or speed of light indicator, to test your reaction times by working in pairs with one student holding the ruler at...

A sheet is shown containing six calculations that have been partially obscured by juice spilled on the sheet. The challenge is to work out what the calculations were, and their solutions.
