This is the third blog post in a series about Counting Principles. These principles are helpful when developing children’s number sense. It’s not enough for them to learn to count by rote, they have to develop a strong foundation of numbers and counting.

One-to-one correspondence is the third principle that I am taking a deep dive into.

What is One-to-Once Correspondence?

It is the ability to count each object in a set once, and only once. This usually involves touching each object while saying the number.

Why is One-to-One Correspondence important?

Developing this skill is vital to be able to solve problems, compare sets, and count the number of objects in a set accurately.

Activities to Work on One-to-One Correspondence Skills
