What RL.9-10.1 Means in Plain English
Ninth and tenth graders back every part of a reading with evidence: what the story states and each inference built on it. One odd moment proves little. A lamp pulled close at noon, dropped screws and a daughter covering mistakes prove a watchmaker is losing his sight.
In 8th grade (RL.8.1) students picked the single line that proved a point best. Grades 9 and 10 want evidence under every claim, the stated ones and the inferred ones alike. In grades 11 and 12 (RL.11-12.1) students also show where the text leaves a question open.
RL.9-10.1 I Can Statements
- I can support every claim in my analysis with text evidence.
- I can separate what a text states from what I infer.
- I can combine several details to prove an inference beyond doubt.
RL.9-10.1 Worked Example
A watchmaker’s daughter covers for him at the counter, and the story never says what she is hiding, so the evidence has to.
When customers asked for her father, Inés said he was in the back, catching up on repairs, and that was true as far as it went.He sat at the bench all afternoon with the loupe screwed into his eye, though she had noticed the lamp now stayed on even at noon, turned so close it warmed his knuckles.Every evening she gathered the tiny screws he had dropped and sorted them back into their trays by size, and she never once asked how they had fallen.When Mrs. Achterberg came for her husband’s pocket watch, he handed over the wrong one, and Inés was already smiling, already swapping it, already saying the mix-up was hers.
Common Mistakes with RL.9-10.1
One quotation carrying a whole analysis
“He is going blind because he gave back the wrong watch.”
Try this: Have students list every claim in their paragraph, then check that each one has its own quotation under it before they revise.
Blurring stated and inferred
“The text says his eyes are failing.” It never does.
Try this: Teach two sentence frames, “The text states…” and “This suggests…”, and require students to sort each claim under one of them.
Ignoring the other reading
Never asks whether one wrong watch could just mean a tired afternoon
Try this: Ask “What else could this detail mean?” and have students add the evidence that rules the alternative out.
