About this resource

Description

The Making Cents Adding Decimals Worksheet helps third graders connect coins to decimal notation. Every coin has a value in cents, and every one of those values can also be written in dollars with a decimal point: a quarter is 25 cents, or $0.25. Once students see that link, adding a handful of coins becomes the same place-value addition they already know, with the decimal point holding the columns in line.

This Making Cents Adding Decimals Worksheet opens with a coin chart that shows a penny, nickel, dime, quarter, and half dollar at their true relative sizes, each labeled with its value in cents and in dollars. Students use the chart to total four coin groups written in words, add two stacked column problems of decimal coin values, and finish with a two-step story problem about money found around the house. Keep the chart in view the whole time so students can check each value before they add.

What’s Included

  • A coin value chart for the penny, nickel, dime, quarter, and half dollar
  • Four problems that turn coin groups into decimal totals
  • Two column addition problems with decimal money values
  • A two-step money story problem
  • A complete answer key

Why It Helps Kids

First, it builds a bridge between the coins children handle every day and the decimal notation they will meet in fourth and fifth grade. Second, the column problems keep every decimal point on one vertical line, so students see why lining up place value matters when they add money. Third, several problems require regrouping in the hundredths place, which gives real practice with carrying rather than simple fact recall. It is a strong 3rd grade adding money worksheet for independent practice or review.

Ideas for Teachers and Parents

Hand out real or play coins and have students build each coin group before writing its total. Ask partners to invent a coin group, write it in words, and trade papers to find the value. At home, empty a coin jar and let a child sort the coins, total each pile as a decimal, and then add the piles together. Each of these keeps money math hands-on and meaningful.
