# K.MD.A.1

Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.

## Summary:

In kindergarten, students begin to understand the concept of “measurement” and the idea that all objects have attributes that can be measured. Length and weight are two attributes with which most kindergartners are familiar. Students should describe attributes (that can be measured) with vocabulary that supports description (taller, bigger, shorter, wider, smaller, heavier, etc.). A statement that any attribute that can be measured or compared is applicable with this standard (i.e., darker versus lighter color might come up in a discussion with children).

## Understanding the Standard:

• Use everyday objects such as a bottle of water to point out to students how the objects have measurable attributes.
• Have balance scales set out for children to explore how different objects can be weighed; then children will begin to understand that some objects are "heavier" and some are "lighter".
• Weight, length, and capacity are different concepts that are most effectively learned one at a time.
• A water center is one way to begin teaching the measurement of volume.
• Teachers should have exploratory activities that allow students to "play" with the different measurable concepts, with objects that have those measurable attributes.

## Questions to Focus Instruction:

• Can students determine that length pertains to how long an object is and that weight pertains to how heavy an object is?
• Can students name several measurable attributes of objects?

## Skills

Prior to: Students can identify objects and distinguish physical differences.
