Measurement:
Measurement concepts and skills are directly applicable to the world in which students live. Many of these concepts are also developed in other subject areas, such as science, social studies, and physical education.
In this strand, students learn about the measurable attributes of objects and about the units and processes involved in measurement. Students begin to learn how to measure by working with non-standard units, and then progress to using the basic metric units to measure quantities such as length, area, volume, capacity, mass, and temperature. They identify benchmarks to help them recognize the magnitude of units such as the kilogram, the litre, and the metre. Skills associated with telling time and computing elapsed time are also developed. Students learn about important relationships among measurement units and about relationships involved in calculating the perimeters, areas, and volumes of a variety of shapes and figures.
Concrete experience in solving measurement problems gives students the foundation neces- sary for using measurement tools and applying their understanding of measurement relation- ships. Estimation activities help students to gain an awareness of the size of different units and to become familiar with the process of measuring. As students’ skills in numeration develop, they can be challenged to undertake increasingly complex measurement problems, thereby strengthening their facility in both areas of mathematics.
