Count off

Count off is a way of organizing a group of people. Let's say you and your friends are going on a field trip. To make sure no one gets left behind, the teacher asks everyone to count off.

Counting off means each person says a number in order, starting from one. For example, the first person says "one," the second person says "two," and so on. This way, everyone knows their number in the group.

If the teacher needs to take attendance or make sure everyone is there, they can simply call out a number and that person responds. If someone doesn't respond or they say the wrong number, the teacher knows that person might not be there or is confused.

Counting off is an easy way to keep track of everyone in a group and make sure no one gets left behind.
