Length resources

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.

Students calculate the lengths of circles and straight lines on an oval athletics track from its given radius and total length, and show their working.

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

This task is about identifying the best unit to measure temperature, weight, time, capacity and length.

Students draw a line from each measurement and unit to its equivalent.

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 identify the correct unit of measurement that would be used for the weight or length of a range of everyday objects.

Students convert the millimetre dimensions of a door to metres and centimetres.

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.

In this practical task students design a net for a lidded cardboard cube to hold a tennis ball. They then cut out and construct the cube.

Students decide if the height, length, or width of everyday objects is less than, or more than, one metre.

Students estimate the height and length of various items around their school.

Students measure images of objects on a centimetre ruler.

This practical task requires students to rank a series of animal pictures in order from shortest to tallest.

Students select the best unit measure of length for a number of situations.

Students calculate and record the length and height of coins in centimetres and metres.

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.
