Adding Fractions (Same Denominator)
Add and subtract fractions with the same denominator, including results greater than one whole (e.g. 5/8 + 6/8 = 11/8)
Lesson
Set out your lesson
“Adding Fractions (Same Denominator) means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Paper strips or a folded circle
- Pencil and labels (1/2, 1/4)
Extra for the adult
Worked example. Fold a strip in half: each piece is 1/2 of the whole.
Optional challenge. For Adding Fractions (Same Denominator), add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Adding Fractions (Same Denominator), not mastery.

Before you open · source notes
Punch recipes add fractions with the same denominator. Supports same-denominator sums, not every unlike-denominator rewrite.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk for the total punch as a fraction and show the same-denominator addition.

Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-12 returned HTTP 200 with no login or payment prompt. Where a teacher solution is present, it is on the same page as the student task; this check did not find a separate locked student view. An adult can use the student view section and should not read a solution aloud. Advertising was not observed in the fetched HTML text; that is not a browser, device, or ad-free guarantee. This is a paper or discussion task, not an automatically marked interactive game. Opening the link does not save practice or assess mastery. Diagrams on the page use missing or filename-only alt text, so they are not an accessible image equivalent. Accessibility still depends on an adult describing the picture.

Check understanding
- Calculate 3/5 + 4/5 = 7/5 and explain it equals 1 2/5
- Subtract 2/6 from 5/6
- Solve addition problems where the sum exceeds the whole: 7/8 + 3/8
“If a recipe uses 5/8 of a bag of flour and then another 6/8, can your child work out the total and explain what the answer means as a mixed number?”
