Choose accessible prices
Use picture cards and play coins. Price an item at twelve baht and explore different ways to pay exactly.
Treat change as a missing part
For a twenty-baht payment on a twelve-baht item, ask how much more twelve needs to reach twenty. Count on or draw the eight-baht change.
A 20-baht payment consists of a 12-baht price and 8-baht change. The two parts add back to the payment.
