2nd Grade Ordering Numbers to 1000 Worksheet: Largest to Smallest and Back

Give a seven-year-old the numbers 91 and 503 and some will say 91 is bigger, because 9 is a big digit. Sorting five numbers at once makes that idea wobble fast. This 2nd grade ordering numbers to 1000 worksheet holds six sets of five numbers, each next to a tall box with a blue arrow. In part 1, your child writes three sets from largest to smallest; in part 2, three more from smallest to largest. The first answer of each part is already written in red, 942 and 2, to show the way. The numbers range from 2 up to 1,000. A second page gives the answer key.

Why length comes before the first digit

Ordering is comparing, repeated. However, with five numbers your child needs a plan, not just a feeling. The first check is length: a three-digit number is always greater than a two-digit one, so 91 sits below 503 even though 9 looks large.

After that, the hundreds digit decides, then the tens, then the ones. That is place value used as a tool, the same idea behind tens and ones, stretched to three digits.

The page builds this step by step. For example, set 2c holds 536, 449, 507, 519 and 576, four of them in the 500s. So your child must look past the hundreds and compare the tens to finish the job.

At the table: 91, 1,000 and the 500s

Begin with set 1a, where 942 is already written. Ask, "Which number comes next going down?"

Set 1b hides a trap: 91 sits among 571, 836, 503 and 920. A child may put 91 near the top. Ask, "How many digits does 91 have?" Then let them move it.

In part 2 the arrow flips. Read the instruction aloud together, since many children keep sorting largest to smallest by habit. Set 2a also holds 1,000, the only four-digit number on the page.

Set 2c is the slow one. Cross out each number once you copy it, so none goes missing. Finally, count: five numbers in, five numbers out.

Price tags, scores and a board game

Three-digit numbers turn up all over the house. Collect a few receipts and ask your child to line them up by total, from smallest to largest. Also, look at page numbers in a chapter book and order three of them.

The board game Chutes and Ladders fits well. At the end of each round, write down where every player stands and put the squares in order: who leads, who trails?

These small sorts make the rule automatic. Once you finish the page, check it with the answer key and praise the method: "You checked the hundreds first every time. That kept the order right."
