In this resource students are given four coordinate points and asked to find the equation of the lines that connect them. The four lines intersect to form a rectangle- can students find the area of the rectangle?

Each student worksheet contains different coordinate points, but the solutions all have...

This problem is an interesting variation on ‘Goldilocks and the Three Bears’. All three bears start eating their porridge at the same time but at different rates. The time is given for Daddy...

The equations of two intersecting lines are given. The challenge is to use Pythagoras’ theorem to show that the triangle formed by the lines and the y-axis is a right-angle. The point of intersection is determined by solving simultaneous equations.

Each example is derived from a pair of perpendicular lines....

In this teacher presentation and collection of student worksheets, the area of each face of a cuboid is given. Students are then asked to calculate the volume.

Each student worksheet contains a different cuboid, but the solutions all have something in common. The teacher presentations highlights two possible...

There are two parts to the DIY Dendrometer resources: 

Part A focusses on how trees grow and their role within both the carbon cycle and the water cycle. Learners are encouraged to take part in a citizen science project which involves creating and installing a DIY...

Produced by ARKive this presentation introduces Charles Darwin as a naturalist. It tells the story of his life, describes how he was influenced and encouraged by the learning of his friends and contemporaries; and describes the voyage of the Beagle from 1831-36. The presentation illustrates Darwin's skills of...

Produced by ARKive in this resource students observe images of different species of finches from the Galapagos Islands. The activity supports students in producing a simple key.

Please note that the ARKive.org website is no longer available, where links are listed for additional information within the...

Using a spreadsheet as a grid of 'pixels', this computing activity teachers how 1's and 0's can store image data. The classroom exercises use images with increasing pixel resolution, looking at how this affects the clarity of the image. Moving from black-and-white images, the students then use grids of colour...

In this Science upd8 activity students take on the role of forensic science technicians who are acting as expert witnesses for the murder of Angel. Students analyse blood splatter patterns to check whether the murder weapon used was a hammer. They also watch a demonstration of a blood viscosity test to check...

This resource develops the concept of finding the slope and equation of a linear graph defined by pairs of coordinates. There is also work on using the slope and y-axis intercept of a straight line to derive its equation.

The initial task for students to consider is to use proportional reasoning to calculate...

This lesson develops the concept of naming and classifying quadrilaterals according to their properties. Students identify the minimal information required to define a quadrilateral. They sketch quadrilaterals with given conditions.

During the first part of the lesson students choose from the words ‘all’, ‘...

This lesson develops the concept of constructing triangles with given conditions. In particular students will:

• Recall and apply triangle properties
• Determine whether a set of given conditions for the measures of angle and/or sides of a triangle describe a unique triangle, more than one...
