Basic Concepts

Counting and Number Sense

Understanding Numbers and Counting

Numbers are everywhere! From counting your toys to the number of stars you see at night, we use numbers every day. In first grade, it's important to know what numbers mean and how to count them in order.

Counting Up and Down

Counting means saying numbers in the right order, like 1, 2, 3, 4, and so on. You can also count backward, which is called counting down: 10, 9, 8, 7...

Recognizing Numbers

It's not just about saying numbers, but also seeing them and knowing what they represent. When you see the number "5," it means five things—like five apples or five fingers.

Comparing Numbers

We can compare numbers to see which is bigger or smaller. If you have 3 cookies and your friend has 7, who has more? Your friend!

Why Counting Matters

Counting helps us keep track of things, play games, and solve problems every day.

Examples

  • Counting the number of crayons in a box.

  • Comparing who has more marbles during playtime.

In a Nutshell

Counting and number sense help us recognize, count, and compare numbers in everyday life.
