Learning objects Squirt: three containers: level 1

TLF ID L1991

Examine the relationships between capacities of containers of the same shape, but different size. Squirt liquids between three containers to establish the proportional relationship. Work out the third 'unlinked' relationship from two known relationships. Express relationships using mathematical notation such as 2a=6b=3c. This learning object is the third in a series of five objects that progressively increase in difficulty. Some objects in the series are also packaged as a combined learning object.

Educational details

Key learning objectives
  • Students use proportions to represent quantitative relationships.
  • Students use the transitive property of equality to find the relationship between three variables.
  • Students express proportional relationships using mathematical notation.
Educational value
  • Encourages the use of the transitive property to establish relative proportions.
  • Students use symbols to express proportional relationships.
  • Randomised generation of containers with a range of volumes and relationships supports repeated use.
