Lesson 25: Teacher Guide & Master Solutions
Interrogative to Declarative • "Whose" Concord
Syntactic Inversion • Answering "Whose" Inquiries:
Children practice converting an interrogative inquiry introduced by the possessive relative pronoun Whose into a complete declarative statement. The response must supply a concrete owner possessing the item and correctly attach the apostrophe ('s), matching demonstrative pronouns (this/that) and number concord (is/are).
Section A: Master Solution Exemplars (Accept reasonable owner names):
1. Whose slate is this? → This is John's slate. (or This is my sister's slate.)
2. Whose table is that? → That is the teacher's table. (or That is Mother's table.)
3. Whose desk is that? → That is Arthur's desk. (or That is the pupil's desk.)
4. Whose book is on the desk? → Mary's book is on the desk. (or The teacher's book is on the desk.)
5. Whose hats are in the closet? → Father's hats are in the closet. (or The boys' hats are in the closet.)
6. Whose ring is on her finger? → Grandmother's ring is on her finger. (or Her mother's ring is on her finger.)
Key Grammar Checkpoints:
• Full Statement Requirement: Do not accept one-word answers like *"John's"*. Require complete statements: *"This is John's slate."*
• Number Concord in #5: Notice the plural subject hats and plural verb are: Father's hats are in the closet.
• Punctuation Shift: The prompt is a question ending in ?, but the answer is a statement ending in a period (.).
