Arrange numbers from smallest to largest or largest to smallest.
Where your child meets this in real life: Ranking items by price, ordering scores, or sorting data
SEAGReady breaks order a set of whole numbers into 3 steps, taught in order so each skill builds on the last.
Order 3-4 numbers with the same number of digits from smallest to largest
Order numbers with different digit counts from smallest to largest
Order numbers from largest to smallest (descending order)
Three free sample questions from our order a set of whole numbers course. Every question comes with a full explanation, and hints that guide without giving the answer away.
Put these numbers in order from smallest to largest: 3,456, 3,214, 3,789, 3,123
Answer: A. 3,123, 3,214, 3,456, 3,789
All numbers start with 3 thousand, so compare the hundreds digits. Hundreds digits are: 4, 2, 7, 1 Ordering these: 1 < 2 < 4 < 7 So the order is: 3,123, 3,214, 3,456, 3,789
Stuck? Start here: All numbers have the same thousands digit (3). What digit should you compare next?
Put these numbers in order from smallest to largest: 85, 950, 1,200, 12,500
Answer: A. 85, 950, 1,200, 12,500
Count the digits in each number: - 85 has 2 digits - 950 has 3 digits - 1,200 has 4 digits - 12,500 has 5 digits For whole numbers, more digits means bigger. 2 < 3 < 4 < 5 digits, so: 85, 950, 1,200, 12,500
Stuck? Start here: When numbers have different lengths, count the digits first. More digits means bigger.
Put these numbers in order from largest to smallest: 234, 567, 89, 123
Answer: A. 567, 234, 123, 89
Descending order means largest to smallest. Count digits: - 567, 234, 123 have 3 digits - 89 has 2 digits (smallest) Among 3-digit numbers, compare hundreds: 5 > 2 > 1 So: 567 > 234 > 123 Descending order: 567, 234, 123, 89
Stuck? Start here: Descending means largest to smallest. Which number has the most digits?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Niamh recorded the number of visitors to four tourist attractions in Belfast last month: Giant's Causeway had 4,567 visitors, Titanic Belfast had 4,321, Ulster Museum had 4,892, and Belfast Zoo had 4,156.
Put these numbers in order from smallest to largest.
4,567, 4,321, 4,892, 4,156
Step 1 of 5
Niamh recorded the number of visitors to four tourist attractions in Belfast last month: Giant's Causeway had 4,567 visitors, Titanic Belfast had 4,321, Ulster Museum had 4,892, and Belfast Zoo had 4,156.
Put these numbers in order from smallest to largest.
From smallest to largest: 4,156, 4,321, 4,567, 4,892.
The key insight: When numbers have the same leading digits, keep moving right until you find a difference!
Watch out: 4,156, 4,321, 4,892, 4,567. Mixing up the order when numbers look similar - always compare digit by digit from the left.
These are the misconceptions we see most often in order a set of whole numbers, including the ones our practice questions are specifically designed to catch.
Struggling with order a set of whole numbers? The real gap is often in one of these earlier topics.
SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
