Clarifications: Each clarification provides an explanation of the indicator/objective to help teachers better understand the concept. Classroom examples are often included to further illustrate the concept. While classroom examples could be shared with the students, the intended audience for the explanation/clarification is the classroom teacher-not the student. In addition, classroom examples may or may not reflect the assessment limits.

Standard 3.0 Knowledge of Measurement

Topic B. Measurement Tools

Indicator 1. Measure in customary units

Objective d. Describe the attributes of length, weight, and capacity

Clarification

When young children recognize that objects have measurable attributes, they are deepening their understanding of measurement concepts. Describing the attributes of an object helps students to think about what can be measured on an object, and that an object can be measured in different ways to find out about its size. For example:

  • A piece of ribbon - How long it is (length).
  • A bag of peanuts - How heavy it is (weight).
  • A glass - How much it can hold (capacity).

Many objects have an attribute that is very specific to its purpose. For example, a bucket's or pail's most measurable attribute is its capacity. When considering fruit at a store, the attribute of weight is the attribute that would be considered. Provide many opportunities for students to examine, compare, and describe a variety of measurable attributes. When students compare two objects, they will be deciding what can be measured.
