For this NEMP task students perform a range of practical measuring tasks including calculations involving time and selection of appropriate units of measuring.
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.
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.
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 order litre and millilitre capacities from smallest to largest, compare given capacities and explain how they know whether one is larger/smaller or the same.
Students calculate an exact square root and estimate approximate square roots by finding the length of the square flower bed of a given area, and give an explanation for their answers.
Students demonstrate their understanding of a graph showing the relationship between the cost of different bottles of drink and the amount each bottle contains. They then explain which bottle of drink is the best value for money paid.
A spatial pattern involving the area of a shape is represented by a table and a diagram. Students describe the rule in words and as an algebraic expression.
Students use substitution into equations to evaluate the number of blocks and total surface areas in shapes of different heights.
The stimulus can be used as a challenging task to try and derive the rules from the spatial pattern. This is classified as Patterns and Relationships.
