Content Descriptor

recognise the relationships between dollars and cents and represent money values in different ways

Elaborations

• investigating the relationship between dollars and cents, using physical or virtual materials to make different combinations of the same amount of money
• representing money amounts in different ways using knowledge of part-part-whole relationships; for example, knowing that $\$1$ is equal to $100$ cents; representing $\$1.85$ as $\$1 + 50$c $+ 20$c$ + 10$c $+ 5$c or $50$c $+ 50$c $+ 50$c $+ 10$c $+ 10$c $+ 10$c$ + 5$c; when calculating change from buying an item for $\$1.30$ from $\$2$, starting from $\$1.30$ add $20$c and $50$c which gives $\$2$
• representing money values in multiple ways when role-playing money transactions; for example, using play money to represent the coins and dollars you could use to pay for items

Year 3 Mathematics Achievement Standard

By the end of Year 3, students order and represent natural numbers beyond 10 000. They partition, rearrange and regroup two- and three-digit numbers in different ways to assist in calculations. Students extend and use single-digit addition and related subtraction facts and apply additive strategies to model and solve problems involving two- and three-digit numbers. They use mathematical modelling to solve practical problems involving single-digit multiplication and division, recalling multiplication facts for twos, threes, fours, fives and tens, and using a range of strategies. Students represent unit fractions and their multiples in different ways. They make estimates and determine the reasonableness of financial and other calculations. Students find unknown values in number sentences involving addition and subtraction. They create algorithms to investigate numbers and explore simple patterns. Students use familiar metric units when estimating, comparing and measuring the attributes of objects and events. They identify angles as measures of turn and compare them to right angles. Students estimate and compare measures of duration using formal units of time. They represent money values in different ways. Students make, compare and classify objects using key features. They interpret and create two-dimensional representations of familiar environments. Students conduct guided statistical investigations involving categorical and discrete numerical data and interpret their results in terms of the context. They record, represent and compare data they have collected. Students use practical activities, observation or experiment to identify and describe outcomes and the likelihood of everyday events explaining reasoning. They conduct repeated chance experiments and discuss variation in results.
