Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
Fractions of a whole means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: Paper strips or a folded circle; Pencil and labels (1/2, 1/4). Adult folds a strip into halves and labels 1/2. Child makes three fair shares (halves/quarters) and names each piece. Done: three correctly named equal parts. Stop after the fresh check; keep optional challenge for another day.

Naming the Whole for a Fraction
Before you open · source notes
Name the whole that makes a pictured piece a unit fraction. This supports fractions of a whole, not every fraction operation.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk what the whole is before naming the fraction. Keep the solution diagram for the adult.

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 2026-11-11 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
- Given a shape divided into 5 equal parts, identify one shaded part as 1/5
- Explain that 3/4 means 3 parts each of size 1/4
- Draw a model showing 2/6 as 2 pieces of a whole cut into 6
“If you cut a pizza into 6 equal slices, can your child explain what 1/6 means — and then work out what 4/6 of the pizza looks like?”
