Building Number Sense
Subitizing is an important mathematical concept that can greatly benefit student achievement in counting on, composing and decomposing numbers, place value and arithmetic. Subitizing is the ability to “instantly see" how many. This method of teaching is achieved when students can spontaneously recognize and discriminate small numbers of objects. Students who can successfully subitize are able to “just know” a group of numbers and recognize the pattern.
