Compare & Order Numbers to 999

What you'll learn

  • Compare two whole numbers up to 999 using the words and symbols greater than, less than, and equal to
  • Order three whole numbers from least to greatest and greatest to least
  • Use place value to explain a comparison

Words to know

Greater than (>) —
the first number is larger
Less than (<) —
the first number is smaller
Equal to (=) —
the numbers have the same value
Compare —
decide which number is more or less
Order —
arrange numbers from least to greatest, or the reverse

Why it matters Comparing numbers helps us tell which is more, such as points in a game or days left, and put a list in a sensible order.

Worked examples

Model ItI do

Compare 348 and 342.

Compare from the left. The hundreds (3) and tens (4) are the same. In the ones place, 8 is greater than 2, so 348 is greater than 342. We write 348 > 342.

Try It TogetherWe do

Order 120, 210, and 102 from least to greatest.

Compare the hundreds first: 102 and 120 both have 1 hundred, but 210 has 2 hundreds, so 210 is greatest. Between 102 and 120, compare tens: 0 is less than 2. Order: 102, 120, 210.

Now YouYou do
