AC9M3M02 Year 3 Mathematics

This Content Descriptor from Year 3 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.

measure and compare objects using familiar metric units of length, mass and capacity, and instruments with labelled markings

Elaborations

• 1 making a measuring tape using metric units of length and using it to measure and compare things; for example, the girth of a tree; explaining that the lines on a ruler show the beginning and end of each unit
• 2 using a strip of centimetre grid paper to measure and compare the length of objects, connecting this with centimetre units on a ruler and using fractions of a graduation to give a more accurate measure
• 3 discussing how the capacity of a container or object usually refers to the amount of liquid it can hold, measured in millilitres and litres; comparing the capacity of different sizes of familiar drinks; for example, \(600\) millilitres, one litre, \(2\) litre and \(3\) litre milk containers
• 4 measuring and comparing the mass of objects and capacity of containers, using measuring jugs and kitchen or other scales and standard metric units of millilitres, litres, grams and kilograms; interpreting and explaining what the lines on the measuring jug or scales mean
• 5 comparing the capacity of different beakers used in science lessons and using the numbered graduations to measure out different capacities of liquid
