Using only nickels, dimes and quarters, there are 29 unique ways to make change for a dollar. It is helpful to use a systematic strategy for substituting coins in finding each unique combination totalling a dollar.

Because four quarters provide the simplest combination using the least coins, this is a helpful starting point.

Some students may find it helpful to make a chart to track solutions. This enables students to adapt learning in this scenario to bigger problems such as finding all ways to make change for a dollar using additional types of coins.
