Measurable Attributes of Objects
Describe and identify measurable attributes of objects such as length, height, weight, and capacity; use comparative language (longer, shorter, heavier, lighter, more, less)
Lesson
Set out your lesson
“Objects have measurable attributes. Weight can feel heavier or lighter. Length can look longer or shorter. We name the attribute we are comparing before we decide.”
Bring to the table
- One closed water bottle with some water in it
- One hardcover book
- One empty cup or small bowl
Extra for the adult
Worked example. “The water bottle is heavier than the empty cup.” “The book is longer than the cup.”
Optional challenge. Order the bottle, book, and cup from lightest to heaviest by carefully lifting each pair, then explain one comparison that led to the order.
What to notice. Save a parent note quoting two comparison sentences your child said.

Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
Objects have measurable attributes. Weight can feel heavier or lighter. Length can look longer or shorter. We name the attribute we are comparing before we decide.
Spend about 10–15 minutes comparing a bottle, a book, and a cup by weight and length.

Longer/heavier comparisons support noticing measurable attributes. Not every unit conversion table.

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
- Identify that a pencil has length and can be measured
- Describe multiple attributes of one object (e.g. a bottle has height, weight, and capacity)
- Use words like 'long', 'heavy', 'full' to describe objects
“If your child picks up a water bottle and a book, can they tell you which is heavier and which is taller — without any measuring tools?”
