Australian Coins and NotesActivities & Teaching Strategies
Active learning builds lasting understanding of currency by letting students handle real objects. Touching coins and notes while solving problems makes abstract values concrete, turning memorisation into meaningful connections between size, colour, and worth.
Learning Objectives
- 1Identify the value of each Australian coin and banknote denomination.
- 2Compare the total value of different combinations of Australian coins and notes.
- 3Explain the purpose of having different denominations of currency for transactions.
- 4Design a specific combination of Australian coins and notes to represent a given monetary amount.
- 5Calculate the total value of a collection of Australian coins and notes.

Sorting Stations: Coin Features
Prepare stations with replica Australian coins grouped by metal colour, size, and edge type. Students sort them, note observations on charts, then verify values using a reference sheet. Extend by matching equivalent sets, like five 20-cent coins to $1.
Prepare & details
Compare the value of different Australian coins and notes.
Facilitation Tip: During Sorting Stations, circulate with a checklist that flags the 50-cent coin’s size versus its value to redirect any student who groups by appearance alone.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Shop Role-Play: Exact Change
Pairs use play money to simulate buying items priced $2.50 to $5. One acts as customer selecting coins/notes; the other as shopkeeper checks totals and gives change. Switch roles after three turns and discuss strategies.
Prepare & details
Explain why we have different denominations of currency.
Facilitation Tip: In Shop Role-Play, limit each customer to three coins or notes to force creative use of higher denominations and build flexibility.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Combination Challenge: Target Amounts
Provide cards with amounts like $3.75. Individually, students select from mixed coins/notes to make exact totals, recording combinations. Share one solution with the class, justifying why it works.
Prepare & details
Design a combination of coins and notes to make a specific amount.
Facilitation Tip: For Combination Challenge, provide larger target amounts like $3.70 so students practise bridging notes and coins without always landing on round amounts.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Trading Game: Optimise Value
In small groups, students start with random coins/notes totalling $5 and trade within the group to reach new targets like $7.45 using fewest pieces. Reflect on efficient denominations.
Prepare & details
Compare the value of different Australian coins and notes.
Facilitation Tip: In the Trading Game, start with low-value targets to build confidence, then increase complexity once students grasp the value hierarchy.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Teaching This Topic
Teach this topic through layered exposure: introduce coins and notes separately, then combine them in authentic tasks. Avoid teaching all denominations at once; instead, group related coins ($1 and $2, 20c and 50c) to highlight relative value. Research shows that mixing visual, kinaesthetic, and verbal tasks strengthens memory and application, so rotate activities to maintain engagement and consolidation.
What to Expect
Students confidently name each denomination, explain its value, and select combinations to reach targets. They articulate why different denominations exist and justify their choices during discussions and role-plays.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Sorting Stations, watch for students who group coins by size before noticing value.
What to Teach Instead
After the initial size sort, ask students, 'If the 50-cent coin is larger than the $1 coin, why does the $1 coin buy twice as much? Use the value labels to regroup and explain the difference.'
Common MisconceptionDuring Shop Role-Play, watch for students who insist exact change must use only one type of coin.
What to Teach Instead
Prompt the cashier to ask, 'Can you pay with other coins that still total $2.30?' Guide students to list two or three combinations on a mini-whiteboard before proceeding.
Common MisconceptionDuring Trading Game, watch for students who treat the $100 note as 'just big money' without considering its function.
What to Teach Instead
Pause the game and ask, 'Would you use a $100 note to buy a $1.50 ice cream? Why or why not?' Have students discuss the practical uses of large denominations versus small ones.
Assessment Ideas
After Sorting Stations, present a mixed collection and ask students to sort by denomination and calculate the total value of each group and the entire set using notes provided.
After Shop Role-Play, give each student a card with an amount like '$4.20' and ask them to draw or list the coins and notes they would use to make exact change.
During the Combination Challenge, pose the question, 'Why do shops need both $2 coins and $5 notes?' Allow students to share examples from their role-play to support their reasoning.
Extensions & Scaffolding
- Challenge early finishers to find the fewest coins or notes for amounts like $4.90 using only coins, then only notes.
- Scaffolding: Provide visual strips showing each coin’s portrait and value for reference during activities.
- Deeper exploration: Invite students to design a new Australian note or coin, explaining the chosen value and features to justify its place in the currency system.
