Students explore a variety of experiences in the use of scale on a number line.
- Two activities are provided. In 'Name the number' students identify the number that corresponds to a highlighted point on the line. In 'Select the spot' students identify where a given number goes on the number line. A ruler is available to assist students after their first attempt.
- The learning objects assist student understanding of scales as diagrammatic representations reflecting the placement of unit lengths along a line; scales are additive and multiplicative, in that parts of scales can be separated and combined and scales can be discrete (whole numbers) or continuous (e.g. decimals, fractions).
- The learning objects provide feedback to the student about accuracy of placement or identification of the number.
