Volume of Cylinder 2
This Virtual Maths resource demonstrates a practical application of the formula for finding the volume of a cylinder. Voids created by auger piling, created when constructing a piled wall, are filled with concrete and the engineer on site has to calculate the volume of concrete required. Also available is a tool which shows a…
Volume of Cylinder 1
This Virtual Maths resource demonstrates a practical application of the formula for finding the volume of a cylinder. A cabinet has to be built to hold drums of oil and the presentation shows how to convert units, before using them to find the radius of a cylinder and thus the diameter. Students then calculate the necessary dimensions…
Surface Area of Semi Cylinder
This practical activity from Virtual Maths provides the net of a semicylinder, which is used to construct a 3-D model and calculate the surface area of the shape. Students are prompted to measure dimensions and find the area of the semicircles and rectangles. Their results are put into a structured table to enable them to find the…

Volume of a Brick
These resources from Virtual Maths include a presentation and video which explain the technique used to find the bulk density of a brick, using the water displacement method. Because a brick is quite a complicated shape, in so much as it is not even and has a rough surface, to calculate its volume accurately it is weighed in air…
Basic Structures
This resource from Virtual Maths illustrates the basic principle of bending moments and shear force. These are the effect that altering a load, both at a point and uniformly distributed on a beam, has on the beam and the reaction forces.
Formulae of Shapes
This activity from Virtual Maths reinforces knowledge of the formulae used for finding perimeter, area and volume of shapes. There are several tools which can be used to calculate the area of a triangle, rectangle or elipse. They show a diagram with the relevant formula and as the values for two dimensions are altered, the diagram…
Transposition of Formula
This resource from Virtual Maths looks at the transposition of formulae by demonstrating the relationship between three terms. Each term can be selected as the subject of a formula and there is an option to substitute numbers for letters, which will allow students to link arithmetic skills to algebraic manipulation. There is also…

Light Survey
This is a practical activity from Virtual Maths where students collect information to be used in a data handling investigation. Students will need to have access to light meters, which are used to measure light readings in natural and artificial conditions at 1m2 intervals. These readings are repeated and students take the average…
Heat Analysis
This resource from Virtual Maths investigates heat loss from a building. The introduction looks at fabric heat loss (external walls, windows, roof etc.) and ventilation heat loss through cracks and openings in the external building fabric (around window frames, door, etc.). Formulae for each type of heat loss are given and students…
Algebra Games
This resource from Virtual Maths reinforces the distinction between equations, expressions and formulae. It is an interactive game with three levels where students use keyboard arrows to manipulate a wheelbarrow in which they catch equations, expressions or formulae as a selection of all three drop down the screen. An explanation…
