What this page helps with
For grades 2-3 and CCSS 2.NBT.A.4, this US Letter PDF contains 13 pages. Six sorting sheets are paired with keys. The sheets labeled 2, 3, and 7 pose 12 prompts apiece: arrange four three-digit values, with Name and Date lines included. Some choices separate at hundreds, others require checking tens or ones, as in 607, 945, 201, 610. Remaining student sheets continue the exercise. Ordered solutions appear in the key section, numbered 8-13.
Compare digits from left to right
To order three-digit numbers, compare their hundreds first because hundreds represent the largest groups. The number with fewer hundreds is smaller. If two numbers have the same hundreds digit, compare their tens; if those match too, compare the ones. This left-to-right check identifies which number is smaller without treating a later large digit as more important than an earlier place.
After comparing a set, place the numbers in a row from the smallest to the largest. For 607, 945, 201, and 610, 201 has the fewest hundreds. The two numbers in the six hundreds come next; compare their tens, 0 and 1, to put 607 before 610. Then 945 is greatest. Recheck adjacent numbers in the row to make sure each is no larger than the one after it.
Worked example 1
Order 800, 678, 511, 359 from least to greatest.
Compare hundreds: 359 has 3, 511 has 5, 678 has 6, and 800 has 8. Each hundreds digit differs, so their hundreds decide the order.
Answer: 359, 511, 678, 800
Worked example 2
Order 607, 945, 201, 610 from least to greatest.
201 has the fewest hundreds. Compare 607 and 610: both have 6 hundreds, but 0 tens is less than 1 ten. 945 has the most hundreds.
Answer: 201, 607, 610, 945
Worked example 3
Order 225, 822, 985, 206 from least to greatest.
Both 206 and 225 have 2 hundreds, so compare tens: 0 is less than 2. The other hundreds digits are 8 and 9, placing 822 before 985.
Answer: 206, 225, 822, 985
How to teach this skill
Use a hundreds chart
Write each number's hundreds digit beside its name and sort those digits first. For numbers with the same hundreds, look only at the tens next, then ones if needed. A place-value chart can hold all three digits in aligned columns and helps children point to the first place where two numbers differ.
Make a number line
Draw a line from 0 to 1,000 and mark broad hundreds landmarks. Ask students to place each three-digit number in the correct interval, then refine positions within that interval. This gives a visual sense of magnitude before they write the exact least-to-greatest sequence.
Compare one pair at a time
For a set of four, select two numbers and decide which comes first by checking hundreds, tens, then ones only as needed. Keep the smaller number at the left of a growing row. Repeat with each remaining number, explaining which place settled every comparison.
Read the order back
Once the sequence is written, compare neighboring entries rather than starting over. Ask whether the next number has more hundreds, or if tied, more tens or ones. If any neighboring pair is reversed, swap and recheck that section. This helps children verify the entire list in a manageable way.

Classroom and home ideas
A place-value launch
Before the worksheet, display four numbers and ask which place should be compared first. Students can identify the hundreds column and explain why it settles many comparisons quickly.
A partner explanation
Pairs can choose one set and justify the order by naming the first differing place in each comparison. Listening for a place-value reason helps an adult spot guesses that happen to be correct.
A sequence check
After ordering a row, cover all but two neighboring numbers and compare that pair. Repeat across the row to confirm the sequence increases at every step.
What usually goes wrong
Putting 945 before 201 because 9 is larger than 2 ignores the hundreds place comparison.
Compare the hundreds digits as whole groups: 2 hundreds is fewer than 9 hundreds, so 201 comes first. Read each number's hundreds aloud before looking at tens or ones.
Ordering 607 after 610 by comparing the ones digits before the tens digits reverses the pair.
Both numbers have 6 hundreds, so compare tens next. Since 0 tens is fewer than 1 ten, 607 is smaller. Look at ones only when both hundreds and tens match.
Placing 225 before 206 because 225 has a smaller ones digit overlooks the tens difference.
The hundreds tie at 2, so compare tens: 0 tens in 206 is less than 2 tens in 225. Therefore 206 comes first, even though its ones digit is larger.
Reversing the direction and listing 800, 678, 511, 359 is greatest to least, not least to greatest.
Check each neighboring pair from left to right. The next number should be greater than or equal to the previous one. Reverse the row to get 359, 511, 678, 800, then verify the hundreds increase.
Questions people ask
How do you order three-digit numbers from least to greatest?
Compare the hundreds digits first. If those are equal, compare tens, and then ones if needed. Put the number with the smaller value at the left and continue until the row rises. For 607 and 610, hundreds tie and 0 tens is less than 1 ten, so 607 comes first.
How to teach ordering numbers with place value?
Put each number in a chart with hundreds, tens, and ones columns. Compare the hundreds column across the set, then use tens or ones only to settle ties. Students can explain which first differing place decides a pair before arranging the whole group from least to greatest.
What is an easy way to order four numbers by place value?
Read the hundreds digits across the set and identify the smallest group first. Where values tie, inspect the tens, then the ones if needed. For 206 and 225, the hundreds match but 0 tens is less than 2 tens. Once arranged, compare neighbors to confirm the row keeps increasing.
