All things Kindergarten Math
Unit 14-
This unit bundles student expectations that address identifying measurable attributes of objects and directly comparing two objects to determine which object has more of or
less of the measurable attribute.
Prior to this unit, in Units 11 and 12, students explored two- and three-dimensional objects. Students learned the prerequisite skills of describing, comparing, classifying, and sorting objects that will be necessary for discerning measurable attributes of objects.
During this unit, students focus on identifying measurable attributes of objects, including length, capacity, and weight. Through repeated direct comparison opportunities,
students develop an understanding of conservation (the length, capacity, or weight of an object does not change when the orientation of the object changes). Comparative
language is used to describe the differences of the attributes between two objects. Students develop appropriate vocabulary for describing the differences for a specific
measureable attribute versus a general term such as bigger. In Kindergarten, the focus of measurement is on direct comparisons using descriptive language rather than
quantity. These direct comparisons begin to provide the foundational understanding that measurement involves a comparison of a measurable attribute of an object to a
quantity of units of measurement.
After this unit, in Grade 1, students will explore the continuous nature of linear measurement. Students will select and use non-standard units of measurement for
determining length.
