Learning objects Cubirocks are measured!


Help three cuboid characters to estimate the volume of cube-shaped rocks made by a special volcano in 'Cubiland'. Each character uses a different measuring unit: small, medium-sized or large. Use a measuring cube to help estimate the volume of different 'cubirocks' made up of cubes. Complete a data table. Volumes range from 1 unit up to 162 units (3x3x3x6). Notice cubic number patterns in your completed data table. This learning object is one in a series of three objects.

Educational details

Key learning objectives
  • Students use ratios to estimate the volume of solids made up of cubes.
  • Students explore relationships between unit size and volume.
Educational value
  • This resource is useful for the Australian Curriculum content description in year 4 mathematics about calculating and comparing volumes of three-dimensional shapes using informal units.
  • It may also be relevant to applying ratios to solve problems at year 7 and to recognizing and using multiples at year 5.
