Learning objects Scale matters: hundreds

TLF ID L2005

Explore the use of scale on a number line. Select a ruler displaying a helpful scale such as hundreds. Look at a pair of numbers such as 900 and 1200 marked on a number line. Identify the number corresponding to another point. Or locate another point on the number line to complete a series of three numbers. Apply a marked scale to help estimate the relative distances. This learning object is one in a series of seven objects. Some objects in the series are also packaged as a combined learning object.

Educational details

Key learning objectives
  • Students locate numbers on a given scale.
  • Students use a scale to measure discrete quantities.
  • Students locate numbers accurately on a continuous scale.
  • Students identify how variations in unit size relate proportionally to the number of units that will fit into a given space.
Educational value
  • Uses scales to relate numbers to each other on number lines.
  • Provides a range of scales to help students relate variations in unit size to the number of units that will fit into a given space.
  • Helps students to apply efficient multiplicative or additive strategies.
  • Random generation of points and numbers supports repeated use.
