How to teach alphabetical order
Kindergarten to Grade 3
Alphabetical order (ABC order) means arranging words by the order of the letters in the alphabet. It is a practical skill for using dictionaries, glossaries, indexes and contact lists. Children first sort by the first letter, then learn to look at the second and third letters when the first ones match.
How to teach it
- Make sure the alphabet sequence is secure first, using an alphabet strip as a reference tool.
- Sort words by their first letter only, physically moving word cards into order.
- Introduce the second-letter rule for words that share a first letter (cat before cup), then the third letter as needed.
- Apply it for real by finding a word in a simple dictionary or glossary, noticing the guide words at the top.
- Progress to ordering longer lists and words that share several opening letters.
Worked example
First letter differs: apple, ball, cat Same first letter, use the second: cap, cat, cup (a before a? compare 2nd: a, a, u) cap before cat (p before t), then cup
Common mistakes
- Sorting by word length or first sound instead of the alphabet.
- Stopping at the first letter when words share it, instead of comparing the next letter.
- Losing the alphabet sequence partway (forgetting where a letter sits).
- Ignoring case or spaces and misplacing a word as a result.
Frequently asked questions
What is alphabetical order?
Alphabetical order, or ABC order, means arranging words by the order of the letters in the alphabet. It is a practical skill for using dictionaries, glossaries, indexes and contact lists. Children first sort by the first letter, then compare later letters when the first ones match.
What age or grade is alphabetical order taught?
Alphabetical order is usually taught from Kindergarten to Grade 3. Young children sort by the first letter, then learn the second-letter rule for words that share a first letter, and apply it to find words in a simple dictionary or glossary.
What is the second-letter rule?
When two words share the same first letter, you compare their second letters to decide the order, and the third letter if the second also matches. So cap comes before cat because p comes before t, even though both start with ca. This rule sorts words that share opening letters.
Why is alphabetical order useful?
Because so many reference tools are arranged that way: dictionaries, glossaries, indexes, contact lists and library catalogues all use it. Knowing alphabetical order lets children find a word or name quickly, using the guide words at the top of a dictionary page to jump to the right place.
What should a child know before learning ABC order?
The alphabet sequence should be secure first, since ordering words depends on knowing which letter comes before which. An alphabet strip kept as a reference tool helps children who are still learning the sequence, so they can check the order rather than losing their place.
Why does my child struggle with alphabetical order?
Common problems are sorting by word length or first sound instead of the alphabet, stopping at the first letter when words share it instead of comparing the next, and losing the alphabet sequence partway. An alphabet strip and practice with the second-letter rule usually help.
What are guide words in a dictionary?
Guide words are the two words printed at the top of each dictionary page, showing the first and last entries on it. They let a reader tell at a glance whether a word falls on that page, so they can flip quickly to the right place using alphabetical order.
