# GM2-1: Create and use appropriate units and devices to measure length, area, volume and capacity, weight (mass), turn (angle), temperature, and time.

This means students will recognise that the attributes length, area, volume and capacity, and weight can be measured. At Level Two students are expected to recognise that measurement units are countable and therefore able to be partitioned and recombined in the same way as other units of one. For example, if an 8 unit length is cut from a 14 unit long strip the remainder will measure 6 units. Units of measure have other characteristics including being a part of the attribute they measure and uniformity (same size). When measuring, the units need to fill a length, space, time etc, with no gaps or overlaps (this is known as tiling). Students should create measurement devices, for example rulers, rod towers, scales, to quantify the attributes of objects in numbers of units. In doing so they should develop an understanding that the marks on a linear scale show the endpoint of units and that scales always have a baseline (zero). Less tangible attributes such as turn (angle), temperature and time should also be measured. While the focus at Level Two is on students’ understanding the role of units in measurement it is also expected that students will encounter simple standard measures such as metres, centimetres, kilometres, minutes, seconds, kilograms, litres, etc, through using everyday measurement instruments.

## Paper Planes Level 2

- Units of Work
- Geometry and Measurement
- Level Two

This unit is the first of two around making paper planes. In this unit students investigate a variety of designs for paper airplanes and experiment to see which planes fly the furthest. They measure how far their planes fly using the standard measures of metre and cm, compare results and have a flying competition.

This unit is suitable for students that have had plenty previous experience with non-standard units and have had the concept of standard units introduced. It provides a good context for practising the use of metres and centimetres. In the second unit, Paper Planes L3, students create scatter plots of the distance their planes travel when a variable is changed.

## All About Me

- Units of Work
- Geometry and Measurement
- Level Two

In this unit we explore the size of a centimetre and measure objects using the centimetre rulers that we have constructed.

## How Much Cereal?

- Units of Work
- Geometry and Measurement
- Level Two

In this unit students consolidate their knowledge of volume by using kitchen measuring cups in a variety of measuring tasks. A stations approach is employed with all the tasks based around the theme of cereal.

## Party Volumes

- Units of Work
- Geometry and Measurement
- Level Two

In this unit students build on previous experiences with litres and millilitres. Work is carried out in the context of planning a party with students measuring volumes accurately as part of the planning process. It is suggested this unit follows the units *Popcorn* and *How Much Cereal?* which involve students working with litres, half litres and cups.

## Angles

- Units of Work
- Geometry and Measurement
- Level Two

This unit uses one of the digital learning objects, Angles, to support students as they investigate measuring and drawing angles using other angles as units of measurement. It is suitable for students working at level 2 of the curriculum because they estimate and measure the size of other angles using other angles and not with compasses and protractors. This unit includes background information on teaching about angles, a sequence that can be used by the teacher when working with a group of students on the learning object, and ideas for independent student work.

## Clockwise

- Units of Work
- Geometry and Measurement
- Level Two

In this unit we develop the concept of angle to see that an angle may be constructed in a clockwise or anticlockwise direction. We see the effect of clockwise and anticlockwise turns on objects. We also think about corners of objects that are equivalent to quarter turns. We also think about whether a corner can be a half turn. These ideas are explored physically.

## Making Benchmarks - Length
