Lesson 10: Using "Are" to Ask Questions - Teacher Answer Key & Explanatory Guide

Plural Interrogative Fluency: Master formulating inquiries about multiple objects opening with capitalized Are.
Determiner Distinctions: Reinforce that plural nouns omit a/an and can be preceded by the, your, these or stand as bare plurals.
Punctuation & Inversion Concord: Consolidate subject-verb agreement across Lesson 9 (Is + Singular) and Lesson 10 (Are + Plural).

Comparative Inquiries: Contrast Lesson 9 vs. Lesson 10 orally: "Is the book new?" • "Are the books new?"
No 'A' in Plural Drill: Strictly correct any attempts to use *Are a slates...?*. Remind pupils: "'A' means one!"
Spoken Intonation: Encourage expressive vocal rise on the final syllable before the question mark.

#	Exemplary Model Question (Accept Creative Answers)	Syntactic Structure	Teacher Evaluation Notes
1	Are the slates clean? (Alt: Are slates useful in school?)	Are + (the) slates + predicate	Must begin with Capital Are; plural noun; question mark (?).
2	Are the desks in neat rows? (Alt: Are the desks wooden?)	Are + the desks + predicate	Check agreement; verify plural noun ending in '-s'.
3	Are the apples sweet and ripe? (Alt: Are apples red?)	Are + (the) apples + predicate	No an before apples! Plural agreement verified.
4	Are your pencils sharp? (Alt: Are the pencils in the box?)	Are + (the/your) pencils + predicate	Meaningful inquiry; check handwriting on ruled line.
5	Are the books on the shelf? (Alt: Are our books new?)	Are + (the) books + predicate	Locational or descriptive predicate; question mark (?).
6	Are those pictures beautiful? (Alt: Are the pictures on the wall?)	Are + (the/those) pictures + predicate	Check capital 'A' in Are; end with mark (?).
7	Are the classroom doors shut? (Alt: Are the doors painted green?)	Are + the doors + predicate	Verify plural noun doors; terminal question mark (?).
8	Are the windows open today? (Alt: Are the windows clean?)	Are + the windows + predicate	Notice new vocabulary windows; verify agreement.

Comparing Questions: Lesson 9 ("Is") vs. Lesson 10 ("Are")

Lesson 9: Singular Inquiries with "Is"
• Is + [the/a + singular noun] + [predicate] + ?
"Is the slate clean?" • "Is the book new?"

Lesson 10: Plural Inquiries with "Are"
• Are + [the/bare plural noun] + [predicate] + ?
"Are the slates clean?" • "Are the books new?"

Illegal Determiner Intrusion: Writing *Are a desks clean?*. Teach: "Never use a or an when you have more than one!"
Singular Noun Slip: Writing *Are the desk clean?*. Ensure child retains the plural suffix '-s'.
Terminal Punctuation Error: Ending with a period (.) instead of (?). Prompt: "Ask yourself: Is this an asking sentence?"
