Counting objects is the process of determining the total number of items in a group. This can involve anything from counting apples in a basket to books on a shelf. The basic principle is to assign a unique number to each item, ensuring that every object is counted only once. Counting can be done using various methods, such as one-to-one correspondence, where each object is paired with a number. This skill is fundamental in mathematics and helps in understanding larger concepts like addition and subtraction. Counting is also essential in everyday life, such as when shopping or organizing toys.
