Ordering numbers means putting them in a clear sequence, such as least to greatest or greatest to least. Young learners can use a number track from 0 to 10 to see which numbers come first and which come later. This matters because ordering helps children compare amounts, count with confidence, and understand place on a number line.
When numbers are lined up in order, patterns become easier to see.

Common Mistakes to Avoid
- Starting with the biggest number when asked for least to greatest is wrong because least to greatest must begin with the smallest number.
- Skipping a number card while ordering is wrong because every card in the group must be placed in the final line.
- Thinking the number farther left is bigger is wrong because on a 0 to 10 number track, numbers grow bigger as you move right.
- Mixing up 6 and 9 is wrong because they are different numbers and belong in different places on the number track.
Practice Questions
- 1 Put these numbers in order from least to greatest: 2, 5, 1, 8, 4.
- 2 Put these numbers in order from greatest to least: 7, 3, 10, 0, 6.
- 3 A card with 3 is to the left of a card with 6 on a number track. Explain which number is smaller and how you know.
