Counting a collection — Data, 4–6 years

Counting tells us how many objects are in a group. Each object needs one number, and the final number tells the size of the whole collection.

One number for each thing

When we count, we touch or point to each object once while saying the number names in order. The last number we say tells how many objects there are altogether. It does not matter whether the objects are big, small, close together or spread out.

Why count carefully?

People count because “a lot” is not precise enough when sharing, checking or comparing. Counting solves the problem of knowing the exact size of a collection. To make the answer trustworthy, we need to avoid skipping an object or counting one twice.

Count six shells

There are six shells on a table. Move the first shell to one side and say “one”. Move the next five shells one at a time, saying “two, three, four, five, six”. You have moved six shells, so there are six shells altogether. The last number is the answer.

The last number matters

A common mistake is to say the counting words but then answer with a number from the middle, or to count one object twice. This is reasonable when objects move, because the eyes can lose track. Touch each object once and keep counted objects apart; then use the last number you said.

Counting in daily life

We count plates before dinner, steps on a walk, seats on a bus or apples in a bag. Shops count items, and families count people when making sure nobody is missing. Counting is useful whenever “how many?” needs a clear answer.
