Comparisons 1 supports reading, writing, and comparing multi-digit numbers on the way to decimal comparisons. Not every fraction strip lesson.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.

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.

- Compare 0.372 and 0.38 using place-value reasoning

“Can your child read and write decimals like 3.047 or 0.625, say what each digit means (3 ones, 0 tenths, 4 hundredths, 7 thousandths), and put a set of decimals in order?”
