When areas and volumes are enlarged the results are far from intuitive. Doubling the dimensions of a rectangle produces a similar shape with four times the volume! Doubling the dimensions of a cuboid produces a similar shape with eight times the volume!
Map Scales: Test your understanding of map scales expressed as ratios with this self marking quiz.
Similar Shapes: Questions about the scale factors of lengths, areas and volumes of similar shapes.
Transformations: Draw transformations online and have them instantly checked. Includes reflections, translations, rotations and enlargements.
Enlargement by a scale factor: A Maths teacher goes through the idea of enlarging a shape from a centre of enlargement.
Enlargements: How to enlarge a shape by a positive scale factor and a centre of enlargement. Includes a scale factor less than 1 and a centre of enlargement inside the shape.
Negative Enlargement: A video from MathsWatch about Enlargement by a Negative Scale Factor.
