Scale factor resources

This task requires students to draw, on a grid, an enlargement of a radio station logo. The scale factor and the centre of enlargement are given. Students answer a question about the area of the original compared to the enlarged logo.

From diagrams of four original and enlarged drawings to be used for Christmas wrapping paper, students identify the scale factor used and find a missing length on either the enlarged picture or the original picture.

This task requires students to enlarge two patterns on a grid using centres of enlargement and scale factors.

Students identify which square, from a selection of five, is the original square resized by a given scale factor.

From three different sized animal pictures and their enlargements, students are required to identify the scale factor and the length of an unknown side.

Students identify the centre of enlargement and the scale factor for an enlargement on a grid.

Using isometric dots, students enlarge a 3-dimensional shape by a scale factor of 2.

On grids, students enlarge shapes by different scale factors through given centres of enlargement.

Students enlarge a diagram to a given scale.
