K.12 - Sort and Classify

The student will 

  • sort and classify objects according to one attribute.


Adopted: 2016

BIG IDEAS

  • So I can describe objects to myself and others in a clearly, making connections with other known items
  • So that I can sort and classify objects in different ways

UNDERSTANDING THE STANDARD

  • Objects can be sorted and classified in different ways.
  • To classify is to arrange or organize a set of materials according to a category or attribute (a quality or characteristic). 
  • General similarities and differences among objects are easily observed by children entering kindergarten, who are able to focus on any one attribute. The teacher’s task is to move students toward a more sophisticated understanding of classification in which two or more attributes connect or differentiate sets, such as those found in nature (e.g., leaves having both different colors and different figures).


ESSENTIALS

The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to

  • Identify the attributes of an object (e.g., color, size, shape, thickness)
  • Sort objects into appropriate groups (categories) based on one attribute (e.g., size – large bears and small bears).
  • Classify sets of objects into groups (categories) of one attribute.
  • Label attributes of a set of objects that has been sorted.
  • Name multiple ways to sort a set of objects.
