AC9E2LY12: Build morphemic word families using knowledge of prefixes and suffixes

1. Outcome Overview & Core Concepts

Prefixes and suffixes are morphemes added to a base word. They create word families and change meaning, grammar or both.

Learning target: build morphemic word families using knowledge of prefixes and suffixes

Big idea: Build related words by adding meaningful parts

Learning routine: Find base → Add prefix or suffix → Read new word → Explain new meaning

4. 4-Step Instructional Sequence

2. Subject-Specific Content & Key Examples

Guided practice

1. Sort and notice — Build word-family trees from common base words.
2. Build or improve — Sort affixes by whether they come before or after the base and explain their effect.
3. Explain your choice — Use the words base word, prefix, suffix to explain what you changed and why.

Curriculum Coverage & Elaborations

The content description is the required target. The elaborations below are taught as examples and contexts, not as disconnected checklist wording.

• E1: using morphemic knowledge of words to spell unknown words; for example, “one”, “once”, “cover”, “covering”, “uncover”
• E2: writing unknown words using morphemic knowledge; for example, using the known word “friend” to write “friendly” and “friendship”

3. Common Student Misconceptions

• Any similar spelling is a family: Word-family members share a meaningful base, not just nearby letters.
• Ignoring meaning changes: Explain what the prefix or suffix contributes.
• Answer without evidence: Point to the word, sentence, image, sound pattern or text feature that supports the answer.

Practice Thought & Formative Assessment

Use a fresh, code-aligned example. The student should show the exact word, sound, sentence, image feature, audience clue or text evidence that supports the answer.

Quick checks

• What is a base word?
• Where does a prefix go?
• What does -ful add?
• Build two words from play.

Mastery evidence

• Identify base words
• Identify prefixes
• Identify suffixes
• Build word families

Revision Notes

• Remember: Build related words by adding meaningful parts
• Use the routine: Find base → Add prefix or suffix → Read new word → Explain new meaning
• Before answering: point to the clue in the spoken words, written sentence, image, page layout or text purpose.
• Self-check: change the example slightly and see whether the same reasoning still works.
