Understanding Numbers

Numbers help us count, measure, and compare things in the world. In 2nd grade, you will work with numbers up to 1,000 and learn how each digit has its own place and value.

Place Value

The place of a digit in a number tells us how much it is worth. For example, in the number 345:

• The 3 is in the hundreds place, so it means 300.
• The 4 is in the tens place, meaning 40.
• The 5 is in the ones place, meaning 5.

Comparing and Ordering Numbers

When we compare numbers, we figure out which is greater or smaller. We use symbols like \( < \), \( > \), and \( = \).

Real-World Connections

Knowing numbers and their values helps you count your toys, read prices at a store, or tell which house number is bigger!

Practice

Try breaking apart numbers to see what each digit means and put numbers in order from smallest to largest.
