This is the ninth 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.

Unitizing is the ninth principle that I am taking a deep dive into.

What is Unitizing?

The broad definition of unitizing is when you bundle a group of objects into smaller sets (like diving an order of boxes onto pallets). With the counting principles, we discuss unitizing as making groups of 10s, 100s, 1000s, etc. This is a shift in using one-to-one correspondence skills, because now 1 can mean 1 bundle of 10. Your kindergarten students may not be ready to internalize this learning, but you should still be exposing them to it.

Why is Unitizing important?

It is the foundation of fractions and place value. Students need to have a clear understanding of unitizing before the can move on to these higher levels of thinking.

Activities to Work on Unitizing

Practice counting by 10s so that when students are ready to begin unitizing, they have the ability to skip count.

Practice unitizing using concrete materials and model how you would count groups of 10.
