Squirt: three containers
TLF ID A002708
Examine the relationships between capacities of various containers. Look at three containers that may have different diameters, heights and shapes. Fill a container and squirt liquids between the containers to establish the proportional relationship. Work out the third 'unlinked' relationship from two known relationships. Express relationships using mathematical notation, for example where a=7b and c=5b, then 5a=7c. In level 3, relationships may be expressed as fractions.
