This Content Descriptor from Year 1 Mathematics provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

compare directly and indirectly and order objects and events using attributes of length, mass, capacity and duration, communicating reasoning

Elaborations

• 1 using a piece of string to indirectly compare the length of several objects, deciding which will fit within a space; using comparative language to describe the order: shortest, short, longer, longest
• 2 ordering the mass of \(3\) or more objects such as rocks, using hefting and balance scales; using comparative language to explain the order: lightest, light, heavier, heaviest, and how they decided on the order
• 3 pouring sand/rice/water from one container to another to compare and order the capacity of \(3\) or more containers; describing the order of the results in terms of which holds the most/least, and those in between
• 4 creating sand timers from everyday items or recycled material and comparing them to order the duration of time required for the sand to run through
• 5 investigating situations where First Nations Australians estimate, compare and communicate measurements; for example, the duration of seasons; understanding animal behaviour using the length of animal tracks; investigating capacity through water management techniques of First Nations Australians, such as traditional water carrying vessels and rock holes
