Resizing resources

Students work out area, length and angles of a shape after enlargement.

Students use their knowledge of transformation to complete an enlargement of a bird by a scale factor of two.

From two different street sign pictures and their enlargements, students are to identify the scale factor of each enlargement and either a missing length or the missing factor when enlarging the area.

Students enlarge a shape on a grid and explore the relationship between scale factor and area.

Students calculate increases in length, area, and volume, and relate this to the scale factor for an enlargement.

Using grids, students enlarge shapes by different scale factors.

Students enlarge shapes by whole number scale factors.

Students identify invariant properties for enlargement.

Students construct enlargements of 2-dimensional shapes using sticks.

Students cut out 2-dimensional shapes and enlarge them by factors of 2 and 3 using paper squares.

Students complete statements which explore the relationship between scale factor enlargements and length, area, and volume of 2 and 3 dimensional shapes.

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

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

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.
