Grade 2: ABC Order

Warm up with a few quick abc order warm-ups on the board while the class settles, so every child starts thinking about the skill.

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. Model the method clearly, thinking aloud:

• 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.

Work this through step by step on the board, then have the class talk you through a second one.

• 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

Do the first few questions of the practice worksheet together, one child explaining each step. Check for understanding before releasing the class to work alone.

Students complete the practice worksheet independently while you circulate and support.

Circulate and look for these, they are the usual sticking points:

• 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.

Pull the class back together. Ask one child to explain abc order in their own words, pose a single check question everyone answers on a mini whiteboard, and name what you will build on next lesson.

Use the independent worksheet as the evidence. A child who can complete it accurately and explain one answer has met the objective; anyone who cannot needs the easier level and a short reteach next session.
