Enlargement resources

Students enlarge a diagram to a given scale.

Students enlarge a shape made of cubes and explore the relationship between the scale factor and volume.

Students work out the missing dimension on a rectangle and show how they obtained it using proportional reasoning.

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.

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.

Students calculate the scale factor and length of one side of a building extension, then draw in a different extension from a given scale factor.

Using grids, students enlarge shapes by different scale factors.

This task requires students to indicate the invariant properties of four transformations (translation, reflection, rotation, enlargement).

Students enlarge shapes by whole number scale factors.

Students enlarge shapes by whole number scale factors.

Students enlarge shapes by whole number scale factors.

Students identify invariant properties for enlargement.

In this practical task students use a ruler, a protractor, and a compass to enlarge an arrow by two given scale factors. They then complete a table to show the invariant properties.

Students identify the invariant properties of a translated and an enlarged shape.

This task requires students to describe the three transformations an animal picture has gone through, choosing from reflection, rotation, translation, and enlargement.

On a grid, students enlarge the net for a box by a scale factor of 3.

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.

This task requires students to indicate, in a table, the invariant properties of four transformations (translation, reflection, rotation, enlargement) of a picture of a traffic light.

Students enlarge shapes by specified increases in each dimension.

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