Tips for Adding Decimals - 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. To learn to add decimals, here are a few tips: Write the numbers down. 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." 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 In this case all the decimal places line up and no carrying is necessary: 2.752 is the end sum. This selection of worksheets and worksheets helps students learn how to find the sums of decimal values.

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.
