Money and financial mathematics
Solve problems involving purchases and the calculation of change to the nearest five cents with and without digital technologies (ACMNA080 – Scootle )
- Recognising that not all countries use dollars and cents, eg India uses rupees.

Measurement and Geometry
Using units of measurement
Use scaled instruments to measure and compare lengths, masses, capacities and temperatures (ACMMG084 – Scootle )
Compare objects using familiar metric units of area and volume (ACMMG290 – Scootle )
- Comparing areas using grid paper

Shape
Compare the areas of regular and irregular shapes by informal means (ACMMG087 – Scootle )
- Comparing areas using metric units, such as counting the number of square centimetres required to cover two areas by overlaying the areas with a grid of centimetre squares
Compare and describe two dimensional shapes that result from combining and splitting common shapes, with and without the use of digital technologies (ACMMG088 – Scootle )
- Identifying common two-dimensional shapes that are part of a composite shape by re-creating it from these shapes
- Creating a two-dimensional shapes from verbal or written instructions
Location and transformation
Use simple scales, legends and directions to interpret information contained in basic maps (ACMMG090 – Scootle )

Compare angles and classify them as equal to, greater than, or less than, a right angle (ACMMG089 – Scootle )
- Creating angles and comparing them to a right angle using digital technologies
Statistics and Probability
Chance
Describe possible everyday events and order their chances of occurring (ACMSP092 – Scootle )
- Using lists of events familiar to students and ordering them from ‘least likely’ to ‘most likely’ to occur
Identify everyday events where one cannot happen if the other happens (ACMSP093 – Scootle )
- Using examples such as weather, which cannot be dry and wet at the same time
Identify events where the chance of one will not be affected by the occurrence of the other (ACMSP094 – Scootle )
