Addition Decimal Operations Worksheets

About Our Decimal Addition Worksheets

Our decimal addition worksheets help students in Grades 4-6 master adding decimal numbers with proper place value alignment. Every worksheet includes a complete answer key for quick feedback.

What Students Will Learn

Students learn to align decimal points when adding tenths, hundredths, and thousandths, progressing from simple problems (2.3 + 1.4) to complex calculations (3.75 + 2.608). Real-world money and measurement contexts make decimal addition meaningful and practical.

How Teachers Can Use These Worksheets

• For place value emphasis: Use grid paper or vertical alignment guides to help students line up decimal points — this is the most common error in decimal addition.
• For money connections: The money-based worksheets directly connect to real-life skills — students calculate total costs, add prices, and balance simple budgets.
• For intervention: Students struggling with decimal alignment benefit from the scaffolded worksheets that include pre-drawn decimal point guides.

How Parents and Homeschoolers Can Use These Worksheets

Connect decimal addition to money immediately: use real receipts, calculate the total cost of items in a shopping cart, or add up allowance savings. The money word problems give children authentic reasons to practice decimal addition. Remind your child: "Line up the decimal points, then add like regular numbers — and don't forget to bring the decimal straight down!"
