Key Learning Concepts

Master these essential comparison skills aligned with 1st grade standards

Compare Tens First

When comparing two-digit numbers, always look at the tens place first. The number with the larger tens digit is greater.

Example:

35 vs 27: 3 tens > 2 tens, so 35 > 27

Compare Ones When Tens Are Equal

If the tens digits are the same, then compare the ones digits. The number with the larger ones digit is greater.

Example:

28 vs 25: Both have 2 tens, but 8 ones > 5 ones, so 28 > 25

Understanding Symbols

> means 'greater than' (opening toward the larger number), < means 'less than' (pointing toward the smaller number), = means 'equal to'.

Example:

35 > 27, 19 = 19, 56 < 65

Step-by-Step Comparison Rules

Follow these systematic steps to compare any two-digit numbers

1

Step 1: Compare Tens Place

Look at the tens digit of both numbers. The number with the larger tens digit is greater.

Example:

42 vs 29 → 4 tens vs 2 tens → 42 > 29

2

Step 2: Compare Ones Place

If tens digits are equal, compare the ones digits. The number with the larger ones digit is greater.

Example:

53 vs 58 → 5 tens = 5 tens, 3 ones vs 8 ones → 53 < 58

3

Step 3: Use Correct Symbol

Choose the right symbol: > (greater than), < (less than), or = (equal to).

Example:

35 > 27, 19 = 19, 56 < 65
