Based on an online sample of 30 students.
Diagnostic and formative information: 
In part b) students ignored the 3 20c coins at the beginning of the row and saw only the $1 coin and the 3 10c coins that make up $1.30.
In part c) students often confused the $1 and $2 coins, selecting the row showing $2.60.
Next steps: 
Using plastic coins can help students recognise their misunderstandings about the values of each coin and assist them with completing any of the following suggested tasks. It can also help them to easily identify the different coins and their values.
 
In pairs, groups or as a class, students could work out all the listed values for each question to check or confirm which one represents the given amount.
 
Students could explore other ways to make each given amount and share their ideas.
 
Students could also challenge a buddy or a group to make any amount they state using notes and/or coins.
 
For students who need more practice with coins these resources could be used to further explore the value of  different amounts of coins:
 
For students who are comfortable with working with coins these resources explore how to make different values using both coins and notes:
