Grade 2 Math Β· World 2: Place Value Peaks Β· Level 20
Compare with >, =, <
Compare three-digit numbers by hundreds, then tens, then ones.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 20
- Which is greater, 432 or 423? To compare, start with the biggest place: the hundreds.
- Both have 4 hundreds. That's a tie, so look at the tens. 3 tens is more than 2 tens, so 432 is greater!
- The symbol with the open side toward the first number means greater than. The other way means less than. The open side always faces the bigger number!
- When the hundreds are different, that's all you need! 610 is greater than 598, because 6 hundreds is more than 5 hundreds.
- The equal sign means both sides are worth the same. 300 plus 40 plus 5 is equal to 345.
