What is Subitizing?
The ability to subitize is an important part of developing a strong mathematical foundation. There are two components of subitizing; conceptual and perceptual. Perceptual subitizing is the instant visual recognition of a pattern such as the dots on a die. Conceptual subitizing is recognizing smaller groups and adding them together, such as two dots plus two dots equals four dots. Understanding “how many” without counting will help children:
Count on from a known patterned set
Combine numbers from sets
Develop mathematical fluency
