These add fractions with like denominators worksheets for grade 4 include two printable activities for computation, mathematical vocabulary, and word-problem practice. Students add fractions that have the same denominator, keep the denominator unchanged, combine the numerators, and record each resulting fraction.
The first worksheet presents eight multiple-choice fraction addition problems. The second page includes four holiday-themed stories with spaces for students to write the numerical sum and describe the answer in words. Together, the two pages provide direct calculation practice followed by meaningful application.
Add Fractions with Like Denominators Worksheets for Grade 4
Fractions with like denominators represent parts of wholes that have been divided into the same number of equal sections. Because the-sized parts are the same, students only need to combine the numerators when adding the fractions.
For example, in the equation 2/13 + 5/13, both fractions describe thirteenths. Students add 2 and 5 to obtain 7 while keeping 13 as the denominator. The completed sum is 7/13.
The central rule practiced throughout the printable PDF is:
- Add the numerators.
- Keep the common denominator.
- Check that the resulting numerator matches the total number of selected parts.
- Simplify only when the lesson or teacher requires it.
Prerequisite fraction practice: Students who need additional support reading fractions with a shared denominator can first complete our compare fractions with same denominators worksheets.
Choose the Correct Fraction Sum
The Choose the Holiday Sum worksheet contains eight multiple-choice questions. Every equation uses two fractions with an identical denominator. Students calculate the sum and circle the correct answer from four choices.
The denominators include 13, 14, 15, 16, 17, and 18. These less familiar denominators encourage students to apply the addition rule rather than depend on memorized fraction facts.
The problems include:
- 2/13 + 5/13
- 6/14 + 4/14
- 3/15 + 8/15
- 9/16 + 2/16
- 5/17 + 7/17
- 10/18 + 3/18
- 1/14 + 12/14
- 8/15 + 6/15
The incorrect options reflect common fraction mistakes. Some choices add the denominators, subtract the numerators, or change both parts of the fraction. Discussing why these choices are incorrect can help teachers identify misunderstandings before students move to more advanced fraction operations.
Holiday Fraction Addition Word Problems
The Holiday Fraction Stories worksheet applies fraction addition to four short real-world situations. Each problem includes a colorful illustration, a line for the fraction sum, and a second line for writing the answer in words.
In the first story, Mia decorates 4/10 of a classroom banner before lunch and another 3/10 after lunch. Students combine the decorated portions to find that she completed 7/10 of the banner.
The second story asks students to combine 5/12 of a sheet of silver paper with 6/12 of a same-size sheet of gold paper. The combined amount is 11/12 of one same-size sheet.
Students also find the total portion of a treat box filled with pretzels and crackers. The equation 7/15 + 4/15 produces 11/15. The final problem combines 8/18 and 5/18 to determine that 13/18 of a display board is covered.
Write Fraction Answers in Words
Writing each result in words reinforces mathematical language. Students should connect a symbolic answer such as 11/15 with the phrase “eleven fifteenths.”
This additional step helps students recognize that the denominator determines the name of the fractional parts. A denominator of 10 represents tenths, 12 represents twelfths, 15 represents fifteenths, and 18 represents eighteenths.
Suggested Teaching Sequence
Begin by reviewing one equation together. Ask students to identify the shared denominator and explain why it remains unchanged. Then have them add the numerators and read the resulting fraction aloud.
Use the multiple-choice worksheet for guided or independent computation practice. Students can show their numerator calculation beside each equation before circling an answer.
Continue with the story worksheet after students demonstrate that they can add like-denominator fractions accurately. Encourage students to underline both fractions in each story, write an addition equation, and check that the denominator remains the same.
Ways to Use the Printable Worksheets
- Whole-class lesson: Solve the first few equations together and discuss common incorrect answers.
- Math centers: Use the multiple-choice page as an independent fraction station.
- Small-group practice: Read each story aloud and identify the quantities being combined.
- Homework: Assign one page after teaching addition with common denominators.
- Quick assessment: Check whether students keep the denominator unchanged.
