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.

Task: Measure 100mL of water into three different pieces of equipment. Weigh the result and calculate the precision of using that piece of equipment. Assessment focus: measuring and evaluating the accuracy of equipment.

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

Students construct enlargements of 2-dimensional shapes using sticks.

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 use the Modified Mercalli intensity scale to assign magnitudes to three described earthquakes. Then they interpret data about the distance from an epicentre, and explain why, from given information, one earthquake might be more damaging than another.

Students design a qualitative scale for measuring how hard their school work is, then use it to record their opinions throughout the day.

Each student designs a question and an associated scale to record other students' attitudes to mathematics.

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

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

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 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

Students use a table of some substances and their pHs to answer four questions.

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.

Explain how to test if a solution is an acid or not, and describe and explain what happens if rusty nails are put in an acid. Assessment focus: acid reactions.

In this practical task, students follow a plan to construct a water timer. They then put on markings for times 1-5 minutes based on observations and recordings.

Students measure images of objects on a centimetre ruler.

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

For this practical task students collect time-series data on the change in water temperature in a container at regular time intervals. Students are also required to display their results on an appropriate graph.

Students use survey data about sports results to estimate the probability of the next person's answer.

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

Students estimate and tally the number of each activity their partner completes in 30 seconds. They then identify the best estimate.
