Comparing Two-Digit Numbers Up to 99
Discover a simple way to compare any two numbers up to 99 by looking at their tens and ones digits, then use greater than, less than, or equal to.
What You'll Learn
Compare the tens digit of each number first since it carries more value than the ones digit
Move to the ones digit only when the tens digits are the same, such as with 34 and 38
Use the symbols \( \gt \), \( \lt \), and \( = \) to record whether one number is greater than, less than, or equal to another
Recognize that a number farther right on a number line up to 99 is always the greater value
Apply place value blocks to see that \( 52 \gt 47 \) because 5 tens is more than 4 tens
What You'll Practice
1
Selecting the larger number from two given numbers up to 99
2
Identifying the smaller number between two values
3
Comparing numbers using visual base-ten models
Why This Matters
Comparing numbers is a fundamental skill you'll use every day, from handling money and telling time to understanding measurements and scores. This foundational skill builds your number sense and prepares you for ordering numbers, rounding, and mental math strategies in future grades.
