Lesson 28: Teacher Answer Key & Guide
TEACHER KEY
Grammar Foundation
Mastering Past Participles: In early grades, children frequently say *"I seen"* or *"He has saw"*. This lesson establishes auditory and kinetic patterns: seen requires an auxiliary partner (have, has, had), whereas saw functions independently as the simple past.
1. Rose saw the white rabbit.
Analysis: No auxiliary verb is present; the simple past saw is required.
2. Charles has seen Ann's pet.
Analysis: The auxiliary verb has precedes the verb; seen must be used.
3. Have you seen the little chicks?
Analysis: The question uses auxiliary Have (inverted: Have you seen); seen is required.
4. Have the children seen their presents?
Analysis: Inverted question with auxiliary Have; requires past participle seen.
Statements with Saw (Standalone Simple Past):
• Exemplar 1: I saw a red robin hopping upon the lawn this morning.
• Exemplar 2: We saw the bright stars shining through our bedroom window.
Statements with Have Seen / Has Seen (With Helping Verbs):
• Exemplar 3: The farmer has seen three fluffy yellow chicks in the barn.
• Exemplar 4: We have seen the large ships sailing upon the wide blue sea.
