Bearings

This interactive excel file begins with a sheet showing a compass rose to help students estimate the bearing of the direction shown. The next sheets allow students to estimate bearings between points shown on a coordinate grid. To calculate the bearings students would need to use the tangent ratio.

Cuboids

This interactive excel file begins with a sheet showing the dimensions of a cuboid beside an oblique drawing of the cuboid. The student needs to calculate the area of the three different faces, the total surface area and the volume of the cuboid. The dimensions can be changed and the net can be shown on a separate...

Geometry: Construction Proof

This resource consists of two interactive excel files dealing with some aspects of construction and geometric proof.

Perpendicular Bisectors
This excel file begins with illustrating the perpendicular bisector of a line segment. It goes on to show the perpendicular bisectors...

Loci

This interactive excel file allows students to investigate loci. Each of the interactive sheets enables students to see random points on or near the locus and how the locus is constructed. Loci include the locus of points equidistant from a point, from a line segment and from two lines. There is an interactive...

Perspective

This interactive excel file allows students to investigate two-point perspective drawings of some simple shapes. The concept is put into context by a picture of the interior of a French church.

The shapes in the investigations are a cuboid, a building with a simple roof and a building with a spire. The...

Polygons (Regular)

This interactive excel file has a series of sheets showing nine different regular polygons. Each polygon can be rotated and also shown with or without the circumscribing circle. They can be shown with or without the radii.

The next sheet shows a table of questions related to these and other regular polygons...

The different types of quadrilateral are illustrated in the first seven interactive sheets of this excel file. Examples of each type of quadrilateral are shown and then further examples illustrated on a coordinate grid. The next sheet is more like a quiz as quadrilaterals are shown and the student is able to check...

Prisms

This interactive excel file shows how the volume of a prism relates to the area of cross section and the length. Various different shapes of cross section are used including pentagons, hexagons, circles and semicircles. In each interactive sheet the cross section can be seen to move through the length of the prism...

Similarity

The first five interactive sheets deal with various types of diagram involving similar triangles. Each sheet shows a clear diagram and a table of values. Lengths of line segments can be revealed to allow the student to calculate the scale factor of enlargement and the remaining lengths.

The next interactive...

Time: Clocks - Analogue and Digital

This excel file has separate sheets dealing with various styles of analogue clock face and different levels of difficulty. It begins with a sheet showing times limited to quarter, half and whole hours. The next two sheets have the numbers removed from the clock face. These first sheets would require teacher input...
