Displays actions that show intuition about parts and wholes such as gathering objects together. Only nonverbally recognizes parts and wholes. Recognizes that sets can be combined in different orders but may not explicitly recognize that groups are additively composed of smaller groups.

Other Examples:

  • When shown 4 red blocks and 3 blue blocks, an infant intuitively appreciates that "all the blocks" include the red and blue blocks, but when asked how many there are in all, may name a small number, such as 1. 
  • An infant notices differences in number and quantity based on physical characteristics of objects and visuals (i.e., stackable cubes, dot cards) by alternating visual tracking and the time spent looking at an object(s)/manipulative(s) of different quantities.

Experiences encourage explorations and appropriate talk of parts and whole in many contexts. Manipulating and grouping all kinds of objects builds foundations for parts and wholes from which all subsequent learning develops.
