Sort and Count II
Before you open · source notes
A second sort-and-count task supports sorting into categories with a new set. Not every probability tree.
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 sort a new set, count each group, and say one rule they used.

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
- Answer 'how many?' for each category in a data set
- Calculate the total number of data points across all categories
- Compare two categories using 'how many more/fewer' language
“If your child looks at a chart showing how many children chose each flavour of ice cream, can they answer questions like "how many chose chocolate?" and "how many more chose vanilla than strawberry?"”
