The Measurement and Geometry strand includes opportunities for students to understand size, shape, relative position and movement of two dimensional figures in the plane and three dimensional objects in space. They investigate properties and apply their understanding of them to define, compare and construct figures and objects. They learn to develop geometric arguments. They make meaningful measurements of quantities, choosing appropriate metric units of measurement. They build an understanding of the connections between units and calculate derived measures such as area, speed and density (ACARA, 2012).
The Measurement strand is divided into five sub strands which contains content descriptors. The content descriptors illustrate the sequence of development of concepts through and across the year levels. They support the ability to see the connections across strands and the sequential development of concepts from Foundation to Year 10 (ACARA, 2012). The sub strand Using unit of measurement is the focus of resource package.
Providing opportunities for students to immerse themselves into measurement sense is important and is dependent on both number sense and spatial sense. Many measurements use aspects of space such as length, area and volume. Others use numbers on a scale such as time, mass a it allows them to understand about problems and solutions. Understanding meanings, representations and relationships among mathematical ideas is an essential aspect of their ability to think mathematically and solve problems (Booker, et al., 2010, p. 41).
