Worksheet 1Add 1/10 + 5/10.
Subtract 4/12 - 1/12.
Maya walked 3/6 mile, then 1/6 mile. How far did she walk?
Which equation decomposes 11/12 correctly?
Which answer matches the shaded fraction model for 3/10 + 3/10?
Add 2/6 + 1/6.
Subtract 3/8 - 2/8.
Maya walked 4/8 mile, then 2/8 mile. How far did she walk?
Which equation decomposes 7/8 correctly?
Which answer matches the shaded fraction model for 3/10 + 4/10?
Adding and subtracting fractions with like denominators depends on understanding what the denominator means is a major fourth-grade math step because students now work with larger numbers, multi-step reasoning, and more precise notation. Students often add both denominators, writing 1/8 + 3/8 as 4/16, even though the size of the pieces has not changed. This worksheet gives short, self-checking questions that rotate through the parts of the skill instead of repeating one template. Students add and subtract like-denominator fractions, solve word problems, decompose mixed numbers, and use visual models to check numerator reasoning. Support versions keep the numbers friendlier while preserving the same reasoning. Standard and challenge versions add larger values, closer distractors, or an extra comparison step. Encourage your child to write down the place, operation, or unit before calculating. If an answer is close but does not match the requested place value, fraction denominator, or measurement unit, it is probably the trap answer.
2/7 + 3/7 = 5/7 because the pieces are sevenths, so only the numerators are added.
Adding the denominators even though the pieces stay the same size.
Keep the denominator the same and work with the numerators.
