Students enlarge shapes by whole number scale factors.

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.

Using grids, students enlarge shapes by different scale factors.

In this practical task, students measure two circular objects to find the circumference, diameter and the relationship between them (pi).

Students read pairs of measurements on linear scales and identify which are greater than, less than, or equal to.

Students calculate or estimate the area for each of three shapes on a grid.

Students are required to describe the compass direction and distance that an ant travels toward different items of food positioned on a grid.

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

For this task students are required to record, in a table, the compass bearings of objects shown on a submarine radar screen. Distances from the submarine are also recorded.

Students use a plan of the school and a scale to answer questions about length and distance of buildings and courts in the school.

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

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

In this practical task, students estimate how many multi-link blocks equal the length of two common classroom items. They then check their estimate with the blocks, then measure with a ruler.

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

Students identify invariant properties for enlargement.

In this practical task, students first estimate, then measure, how many 500ml jars it takes to fill a 1 litre and a 3 litre container

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.

Students measure images of objects on a centimetre ruler.

Students read scales to measure images of objects to the nearest tenth of a centimetre.

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

Students match pictures of objects with a list of capacities involving litres and millilitres.

Using given trigonometry ratios, students calculate distances in practical problems.

Students identify the approximate capacities of everyday containers.

This task requires students to calculate the size of angles using their knowledge of angles and parallel lines: alternate angles, corresponding angles and co-interior angles. Understanding of adjacent angles on a straight line is also required.

Students work out the area of different shapes.
