Counting Small Collections of CoinsActivities & Teaching Strategies
Active learning works for counting coins because young students need concrete, sensory experiences to connect abstract numbers to real objects. Handling real coins and moving them into groups helps bridge the gap between counting by ones and using more efficient strategies like skip counting. Movement and discussion also keep engagement high while building both procedural skills and conceptual understanding.
Learning Objectives
- 1Calculate the total value of small collections of Australian coins up to 50 cents.
- 2Classify Australian coins (5, 10, 20, 50 cents) by their denomination.
- 3Explain how skip counting by fives and tens aids in counting coin collections.
- 4Design a strategy for efficiently counting a mixed collection of coins.
- 5Compare different combinations of coins that sum to 20 cents.

Sorting Stations: Mixed Coin Collections
Prepare trays with 10-15 mixed Australian coins at four stations. Students sort by denomination, skip count each group, record subtotals, and add for the total. Groups rotate stations and share one strategy learned.
Prepare & details
Design a strategy for efficiently counting a mixed collection of coins.
Facilitation Tip: During Sorting Stations, model placing coins in labeled trays while naming each value aloud to build auditory and visual connections.
Setup: Groups at tables with problem materials
Materials: Problem packet, Role cards (facilitator, recorder, timekeeper, reporter), Problem-solving protocol sheet, Solution evaluation rubric
Shop Role-Play: Exact Change Challenges
Pairs take turns as shopkeeper and customer. Customers select items totaling 20 cents; shopkeepers use coins to give exact change. Switch roles and discuss efficient coin choices afterward.
Prepare & details
Explain how skip counting can help when counting coins.
Facilitation Tip: In Shop Role-Play, circulate with a small basket of coins to drop exact change into, so students see the value in action.
Setup: Groups at tables with problem materials
Materials: Problem packet, Role cards (facilitator, recorder, timekeeper, reporter), Problem-solving protocol sheet, Solution evaluation rubric
Skip Count Relay: Coin Lines
Lay out lines of identical coins (e.g., 10-cent pieces) for teams. One student at a time skip counts aloud while placing a finger on each coin, then tags the next teammate. First team to finish records the total.
Prepare & details
Evaluate different ways to make 20 cents using various coins.
Facilitation Tip: For Skip Count Relay, stand at the finish line to receive each group’s counted coins and total, listening for clear skip counting language.
Setup: Groups at tables with problem materials
Materials: Problem packet, Role cards (facilitator, recorder, timekeeper, reporter), Problem-solving protocol sheet, Solution evaluation rubric
Combination Match-Up: Make the Amount
Provide cards showing amounts like 15 cents and trays of coins. Individually or in pairs, students select and arrange coins to match, then count aloud to verify. Record and compare with a partner.
Prepare & details
Design a strategy for efficiently counting a mixed collection of coins.
Facilitation Tip: In Combination Match-Up, sit with struggling pairs to model recording combinations as equations before they attempt independently.
Setup: Groups at tables with problem materials
Materials: Problem packet, Role cards (facilitator, recorder, timekeeper, reporter), Problem-solving protocol sheet, Solution evaluation rubric
Teaching This Topic
Teachers should avoid rushing students to skip counting before they’re fluent with one-to-one counting. Start with visual and tactile sorting so students notice differences in size, color, and value. Use peer discussion to normalize mistakes and encourage students to explain their thinking. Research shows that students learn money concepts best when they physically manipulate coins and connect actions to verbal counting sequences.
What to Expect
Students will confidently sort coins by value, use skip counting to find totals, and explain their counting methods with clear reasoning. They will compare different ways to make the same amount and justify their choices. Success looks like accurate totals, fluent counting, and students volunteering their strategies during group sharing.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Sorting Stations, watch for students treating all coins as equal. They may group coins by size rather than value.
What to Teach Instead
Prompt students to read the value printed on each coin while sorting, and ask them to explain why a 20c coin is worth more than a 5c coin despite being smaller.
Common MisconceptionDuring Skip Count Relay, watch for students counting each coin by ones even when they belong to the same group.
What to Teach Instead
Stop the group and model counting the coins aloud using skip counting by fives or tens, then ask the students to repeat the count together before resuming the relay.
Common MisconceptionDuring Combination Match-Up, watch for students swapping a 10c coin for two 5c coins without verifying the total.
What to Teach Instead
Ask them to place the coins on the table and count each set aloud, then compare the totals to see why swapping changes the value.
Assessment Ideas
After Sorting Stations, present each student with a mixed collection of 5c, 10c, and 20c coins (e.g., three 5c coins, two 10c coins, one 20c coin). Ask them to write the total value and show their working on a mini-whiteboard.
After Shop Role-Play, ask students: 'Imagine you have a 20c coin. What are two different ways you could make 20c using only 5c and 10c coins? Have students discuss in pairs before sharing their answers with the class.'
During Combination Match-Up, give each student a small bag with 3–4 coins (e.g., 10c, 5c, 10c). Ask them to count the total value and write one sentence explaining the strategy they used to count the coins before leaving the activity.
Extensions & Scaffolding
- Challenge: Ask students to find all possible combinations of 5c and 10c coins to make 30 cents, recording each set.
- Scaffolding: Provide coin stamps or stickers so students can record their collections before counting aloud.
- Deeper exploration: Introduce a 50c coin and ask students to find three different ways to make 50 cents using any combination of coins.
Key Vocabulary
| Coin | A small, flat, round piece of metal used as money. In Australia, these include 5, 10, 20, and 50 cent pieces. |
| Denomination | The face value of a coin, indicating how much it is worth. For example, the 10-cent coin has a denomination of ten cents. |
| Collection | A group of coins gathered together. This topic focuses on counting small groups of these coins. |
| Total Value | The sum of the values of all the coins in a collection. It represents the total amount of money. |
| Skip Counting | Counting forward by a specific number, such as counting by fives (5, 10, 15) or tens (10, 20, 30). This helps count groups of coins quickly. |
Suggested Methodologies
Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
