Simple Fraction Sums
Add and subtract fractions with the same denominator within one whole (e.g. 5/7 + 1/7 = 6/7)
Lesson
Set out your lesson
“Simple Fraction Sums 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 Simple Fraction Sums, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Simple Fraction Sums, not mastery.

Unit-fraction sums support simple fraction addition. Not every unlike-denominator shortcut beyond the task.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk the learner to write one sum of unit fractions that matches a given fraction.

Source, access and review notes
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 2/5 + 2/5 = 4/5
- Calculate 6/8 − 3/8 = 3/8
- Explain that when denominators are the same, you add/subtract the numerators
“If a recipe calls for 2/8 of a cup of milk and then another 3/8 of a cup, can your child work out the total without a calculator?”
