K.MD.A. Measurement & Data: Describe and compare measurable attributes.
Students Can:
- Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object. (CCSS: K.MD.A.1)
- Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter. (CCSS: K.MD.A.2)
Academic Contexts and Connections:
Colorado Essential Skills and Mathematical Practices:
- Make sense of their world by comparing and ordering objects by their attributes. (Entrepreneurial Skills: Inquiry/Analysis)
- Be precise about meanings related to size when describing an object's height, weight, or other attribute. (MP6)
- What does it mean for one object to be "bigger" than another?
- If you are standing on a chair, how should your height be measured differently than if you were standing on the floor?
- If an object is moved, does that change its size?
- This expectation is in addition to the major work of the grade.
- In preschool, students develop conceptions of measurable attributes of objects and comparisons based on those attributes.
- In kindergarten, this expectation can contribute to students’ understandings of measurable attributes, comparison, and conservation of length, all of which connect to progressions in geometry, the number system, and to future work in ratio and proportion.
- In Grade 1, students measure lengths directly and by iterating length units, and express the length of an object as a whole number of length units.

- MP1. Make sense of problems and persevere in solving them.
- MP2. Reason abstractly and quantitatively.
- MP5. Use appropriate tools strategically.
K.MD.B. Measurement & Data: Classify objects and count the number of objects in each category.
Students Can:
- Classify objects into given categories; count the numbers of objects in each category and sort the categories by count. (Limit category counts to be less than or equal to \(10\).) (CCSS: K.MD.B.3)
Academic Contexts and Connections:
Colorado Essential Skills and Mathematical Practices:
- Group objects into categories to help make sense of problems. (MP1)
- Abstract individual objects into new conceptual groups. (MP2)
- Choose appropriate representations of objects and categories. (MP5)
- How can numbers of objects be represented to make comparisons?
- How can objects be categorized in different ways?
- How can an object's attributes determine if it does not belong with other objects in a group?
- This expectation supports the major work of the grade.
- In preschool, students use differences in attributes to make comparisons.
- In kindergarten, this expectation supports the work of counting and comparing numbers and is part of a progression of learning how to analyze categorical data.
- In Grade 1, students organize, represent, and interpret data with up to three categories.
