The worksheet titled "Making Change: Find the Correct Combination of Bills and Coins" is all about figuring out what types of bills and coins add up to the amount shown. For example, one question asks, "Pam has $20.13. She has 2 bills and 17 coins. How?" Higher grade-level worksheets include problems like "Use the fewest bills and coins to make $32.58."

All worksheets frame the solution according to grade level. For example, lower levels provide empty boxes for bills and circles for coins to help students organize their thoughts and double-check their work. Upper-grade levels use blank boxes and circles for the first question, but subsequent questions come with an empty space where students can write out their thinking on their own.

Counting money is an important skill for students to learn. It also poses a unique math challenge because bills and coins come in different amounts, which can encourage students to skip count or group numbers together when counting.

Using actual money or play money is an effective way for students to experience money counting firsthand. Bills and coins can also be represented on worksheets to give students practice without access to manipulatives.

Students can start by counting or subtracting money to find an answer. Questions can also ask what combination of bills and coins equals a certain amount, how many ways they can make the same amount, or how they can use the fewest bills and coins to make an amount like $11.54.
