What RI.2.4 Means in Plain English

Second graders work out the meaning of subject words in science and social studies texts, using the sentences around them. A text on coconuts never defines germinate, but it shows a shoot pushing out and roots growing down, and that is enough to figure it out.

In 1st grade (RI.1.4) children asked and answered questions to clear up a puzzling word. Second grade ties the words to the subjects children are studying. In 3rd grade (RI.3.4) general school words like compare and describe join the subject words.

RI.2.4 I Can Statements

  • I can figure out a science or social studies word from clues.
  • I can find the sentences that help me understand a new word.
  • I can check a word’s meaning by putting it back in the sentence.

RI.2.4 Worked Example

A science passage that uses germinate without defining it, one question about the word, and two answers: one that borrows a nearby phrase and one that uses the clues.

Read the Story
A coconut is a giant seed. It has a hard shell inside a thick, hairy husk.The husk is full of air, so a coconut that falls into the sea can float for weeks.When waves wash it onto a warm, sandy beach, it can germinate. A green shoot pushes out through the husk, and roots grow down into the sand.A coconut that stays cold and dry will not germinate. It needs warmth and water before it can start to grow.Years later, that little shoot can be a tall coconut palm.
A short passage written for this page.
Question: What does germinate mean? Which words in the text helped you figure it out?
Not Yet“Germinate means to wash up on the beach.”The child took the phrase just before the word. It fits that one sentence, but it falls apart in line 4: a coconut that stays cold and dry “will not wash up on the beach” makes no sense.
Meets the Standard“Germinate means a seed starts to grow. Right after the word, a shoot pushes out and roots grow down. And a cold, dry coconut will not germinate because it needs warmth and water to start to grow.”The meaning comes from two clues in two places, and it still makes sense when the child puts it back into both sentences.
Question Stems to Use
What do you think this word means?Which words near it give you a clue?Put your meaning back in the sentence. Does it still make sense?Does the word show up again? What does that sentence add?Where else could you check, like a glossary?

Common Mistakes with RI.2.4

Borrowing the nearest phrase

“Germinate means to wash up on the beach.”

Try this: Teach the swap test: read the sentence again with the meaning in place of the word and listen for nonsense.

Stopping at the first clue

A meaning built from one sentence when the word appears twice

Try this: Have students find every place the word appears and underline a clue near each one before deciding.

Skipping the word entirely

The child reads “germinate” as “something” and keeps going

Try this: Stop at each bold or new subject word and ask for a guess and the clue behind it before reading on.
