Equal sharing means every group gets the same amount. We give one to each group in turns, then count to check that the shares match. That is early division.
Spend about 10 minutes sharing objects equally onto plates and counting the equal shares.

Two Interpretations of Division
Before you open · source notes
The same 12 ÷ 3 story is told as equal sharing and as equal grouping. This is a division-as-sharing/grouping supplement; ribbon lengths are fictional.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk how the ribbon is cut in each story and why both use 12 ÷ 3. Keep the solution for the adult.

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
- Share 10 counters (real or on-screen) equally between 2 plates
- Group 20 objects into sets of 5 and find there are 4 groups, e.g. by skip counting 5, 10, 15, 20, or alternatively by subtracting 5 repeatedly (20, 15, 10, 5, 0)
- Use concrete objects or a drawing to solve 'How many groups of 2 in 8?'
“If your child has 12 grapes to share equally between 3 friends, can they work out that each friend gets 4 — and explain what they did?”
