### SUBITIZING SEBAGAI KEMAMPUAN MENDASAR BAGI ANAK USIA DINI UNTUK MENGUASAI KONSEP BILANGAN

#### Sari

The concept of numbers is closely related to counting and arithmetic. Counting is

concerned with knowing how many of a given set of objects. To find out how many, maybe what

can be done is just by counting one by one. However, if the set is small, say 1 to 4, or 5, then the

viewer is able to state how many instantly, without counting it directly. This capability is known

as subitizing. Things relating to counting and arithmetic, should begin with an understanding of

subitizing skills, because if we want to know how many by counting one by one, it will be less

effective. It is possible that early children can do subitizing. Therefore, it is very important for

teachers and also early children to understand the ability of subitizing as a fundamental ability

to perform calculations. With such understanding it is strongly recommended to teachers to

provide facilities that can practice the subitizing ability to early childhood. In this paper, we

discuss about the notion of subitizing, type of subitizing, what factor that make subitizing easy

or hard, how the subitizing relationship with counting and arithmetic, and how to develop

subitizing skills.
