Decimal Addition Worksheets

Finding the sum of two decimal values is very similar to working with whole numbers. It is all about focusing on where the decimal point belongs. This is an important skill because it relates directly to finding sum on money since dollars are often represented as the whole number value of a decimal and cents are represented by the decimal portion to the hundredths place. I encourage teachers to first go over adding a whole number value to a decimal value. That approach tends to help students visualize this process a bit better. This selection of worksheets and worksheets helps students learn how to find the sums of decimal values.

Aligned Standard: 6.NS.B.3

  • Answer Keys - These are for all the unlocked materials above.

Homework Sheets

I feel that it is very important for students to set up their own problem area with decimals.

  • Homework 1 - There is no carrying of numbers in this problem, so everything is very straight forward.
  • Homework 2 - Add the digits beginning with the number furthest to the right after the decimal, rename 10 as 1 + 0. Place 1 over the tens and add the carried number over to it.
  • Homework 3 - These go out to the thousandths place. We work on adding values in the thousandths.

Practice Worksheets

More of the same, but practice sheet 3 sometimes throws them off with the wording.

  • Practice 1 - Now add the digits before the decimal beginning with the ones. Then push your mind to right of the decimal.
  • Practice 2 - Add the following 33.333 & 33.333. We could just save time and multiply them.
  • Practice 3 - Find the sum of the decimals: 12.173 & 13.219. Set these up vertically.

Math Skill Quizzes

We throw a little sprinkle of algebra in here to cover two standards in one.

  • Quiz 1 - Example: 22 + __ = 22.3. What is the missing piece?
  • Quiz 2 - Straight up problems to solve. Whole only numbers are in some problems.
  • Quiz 3 - Fill in the blanks to complete the equations. This mixs up the other two quizzes.

Tips for Adding Decimals

Adding 1.452 to 1.3

Learning to add decimals can be a bit tricky at the beginning. It requires careful consideration of the numbers and where the decimal needs to be placed. It is very similar to adding whole numbers, but you just need to pay attention to the decimal point belongs. This comes down to alignment and properly organizing yourself throughout this process.

To learn to add decimals, here are a few tips:

Write the numbers down in a vertical fashion. Each number below the other and all the decimal points lined up. It is important to line up the decimals so that the addition can take place smoothly.

Put in zeros so that the numbers can have the same length. The reason we add extra zeros is that it is an indication that "there is no value at the place of this decimal". For example, In the number 10, it indicates that there is "no ones." by using the zero at the ones place. In number 2.50, it indicates that there are no "no hundredths."

Then comes the main part, addition. Add using the columns, remember to put the decimal points in the answer. Let's learn it using an example: Adding 1.452 to 1.3.

Step 1) Line them up.

Step 2) Fill in zeroes.

Step 3) Add the values form lowest to highest place value. In this case all the decimal places line up, and no carrying is necessary: 2.752 is the end sum.
