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

Elaboration on this Achievement Objective:

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 uses the context of making paper planes to develop understanding of metre and centimetre measures. Students investigate a variety of paper airplanes designs, experiment to see which planes fly the furthest, and decide winners by measuring and comparing results.

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.

Angles

Units of Work
Geometry and Measurement
Level Two

This unit uses one of the digital learning objects, Angles, to support students as they estimate, and investigate measuring and drawing angles using other angles as units of measurement.

Weights

Problem solving activities
Geometry and Measurement
Level Two

Measure using grams

Apply addition to a measurement problem

Devise and use problem solving strategies to explore situations mathematically (be systematic, use equipment).

How many strips?

Problem solving activities
Geometry and Measurement
Level Two

Measure using cm and metres

Use additive strategies

Devise and use problem solving strategies to explore situations mathematically (use equipment)

Snails

Problem solving activities
Geometry and Measurement
Level Two

Measure using cm.

Solve problems using minutes as the unit.

Devise and use problem solving strategies to explore situations mathematically

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

Units of Work
Geometry and Measurement
Level Two

In this unit we will explore the idea of having benchmarks of 1 metre, 1/2 metre, and 1 centimetre to aid in estimating the length of given objects.

Pirate Plays

Units of Work
Geometry and Measurement
Level Two

In this unit we explore the size of a metre and develop our own ways to estimate a metre length.

Make a Measurement Maths Trail

Units of Work
Geometry and Measurement
Level Two

In this unit students pose measurement questions, make estimates and carry out practical measuring tasks using appropriate metric units.They first complete a trail devised by the teacher and then devise and complete a maths trail of their own.

Outlining Area

Units of Work
Geometry and Measurement
Level Two

This unit of work begins with an exploration of shapes that can be made with centimetre cubes. We draw around classroom objects then use centimetre squared paper to work out the area of their outlines.

Popcorn

Units of Work
Geometry and Measurement
Level Two

This unit is made of a number of popcorn investigations, which provide both a purposeful and enjoyable measuring context. The focus of the unit is introducing the students to the need for a standard unit for measuring volume.

Making Benchmarks - Mass

Units of Work
Geometry and Measurement
Level Two

In this unit we will explore the idea of having benchmarks of 1 kilogram and 1/2 kilogram or 500 grams to aid in estimating the mass of given objects.

Weighing Stations

Units of Work
Geometry and Measurement
Level Two

In this unit students work at a variety of stations involving practical measuring tasks. Estimation skills and the ability to measure accurately using kilograms and grams are developed.

Great Grams

Units of Work
Geometry and Measurement
Level Two

This unit comprises 5 stations which develop our concept of the "feel" of a gram. The stations may be taken as whole class activities or they may be set up as activities that groups of students use throughout the week.

Just a Minute

Units of Work
Geometry and Measurement
Level Two

In these five activities the students develop an understanding of the duration of minutes and seconds. We also practice reading time by counting the minutes after the hour.

Clock Wise

Units of Work
Geometry and Measurement
Level Two

In this unit students explore hours and half-hours and experiment with two ways of telling these times, using digital and analogue approaches.

How long does it take?

Units of Work
