RI.3.4
Determine the meaning of general academic and domain-specific words and phrases in a text relevant to a grade 3 topic or subject area.
Objective
Students will be able to sort words in an information text into subject words and academic words, and work out each meaning with the strategy that suits its kind.
Students are successful when they can
- Sorts words from the text into "subject words" and "academic words" and says why.
- Uses the glossary or a text clue for a subject word.
- Uses the sentence and other subjects for an academic word.
- Gives a meaning that makes sense when swapped into the sentence.
What you need
- "The Water Cycle" (five sentences, below), displayed and one copy per pair
- A mini-glossary: evaporate, water vapor, condense, precipitation
- Eight warm-up word cards and two sorting columns: Subject words, Academic words
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — which subject?
5 min- Show eight cards: multiply, island, volcano, fraction, describe, compare, explain, evaporate. Ask pairs which lesson each belongs to.
- Most pairs place multiply and fraction in math, island and volcano in geography, evaporate in science — then get stuck on describe, compare and explain.
- Ask: "Which lesson does compare belong to?" Take "all of them." Write on the board: "Subject words belong to one subject. Academic words turn up in every subject."
Teach — two kinds, two strategies
13 min- Read the text: "The water cycle is the process that moves water around the Earth. When the sun warms a lake, some of the water evaporates and rises into the air as water vapor. High in the sky, the air is colder, so the vapor condenses into tiny drops that form clouds. When the drops grow heavy, they fall as precipitation — rain, snow or hail. Scientists compare the rain each month to describe how the weather is changing."
- Take a subject word: "precipitation." Show the two places its meaning lives: the dash after it ("— rain, snow or hail") and the glossary. Subject words are usually explained, because the writer knows they are new.
- Take an academic word: "process." Look in the glossary — it is not there. Ask: "Where else have you heard process?" Take math ("the process for column subtraction") and art ("the process of making clay pots").
- Combine the sentence and the other subjects: a process is a set of steps that happen in order. Swap it in: "The water cycle is the set of steps that moves water around the Earth." It fits.
- Take "form" in "tiny drops that form clouds." Some students will offer "a sheet you fill in." Swap it in: "drops that a sheet you fill in clouds" — nonsense. In this sentence form means "make." Academic words shift a little with the sentence, so always swap and reread.
- Sort the four bold words and the four academic words into the two columns on the board.
“Nobody puts "process" in a science glossary, because it is not a science word — it is an everywhere word. For a subject word, look for the clue or the glossary. For an everywhere word, use the sentence and what you know from other lessons.”
Guided practice — sort and define
12 min- Pairs take six words from the text: evaporates, water vapor, condenses, compare, describe, cycle.
- They sort each, then write a meaning using the right strategy and a note saying which strategy they used ("glossary," "clue in the text," "sentence + other subjects").
- Expected academic meanings: compare — look at two things to see what is the same and different; describe — tell what something is like.
- Discuss "cycle." Some pairs will put it in subject words (water cycle) and some in academic (bicycle, life cycle). Accept either with a reason: it means something that goes round and repeats.
- Every pair swaps their meaning into the sentence and reads it aloud to check it fits.
“Swap your meaning in and read the sentence aloud. If it sounds wrong, the meaning came from somewhere else, not from this sentence.”
Independent practice
8 min- Students complete the printable practice sheet: a short passage, a glossary and a set of words to sort and define.
- Prompt anyone stuck on an academic word with: "Where else have you heard it?"
Close — one everywhere word
2 min- Say "describe." Take a meaning and two other subjects where students have met it (e.g. "describe a shape" in math, "describe a character" in English).
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Puts "compare" and "describe" in the subject-words column.
Why: Students have only ever been taught vocabulary as subject words — the bold words with a glossary entry — so every unfamiliar word looks like one. Academic words are rarely taught by name.
Fix: Teach the math-lesson test: "Would you hear this word in math AND science AND English?" Compare and describe pass; condense does not. Run the test aloud for each word in the sort.
Searches the glossary for "process," finds nothing and leaves it blank.
Why: The glossary is where meanings have always been, so when it fails the student believes the meaning is unavailable. They do not yet have a second strategy.
Fix: Sort before searching. The sort tells you which strategy to use: subject word → glossary or text clue; academic word → the sentence plus other lessons. Model "process" with the math and art examples.
Says "form" in "drops that form clouds" means "a sheet you fill in."
Why: A meaning from another context arrives first, and it is a real meaning of the word. The student remembered correctly but did not check it against this sentence.
Fix: Swap and reread: "drops that a sheet you fill in clouds" is nonsense, so that meaning is wrong HERE. Ask what the drops do to the clouds — they make them. Teach that academic words shift slightly with each sentence.
If they are not there yet
- Give the sort already done and ask only for meanings, with the glossary words highlighted.
- Work with three words (precipitation, process, compare) rather than six.
- Provide a "where else have I heard it?" card listing math, science, English and art for academic words.
If they finish early
- Find an academic word that means something different in two subjects — "product" in math (the answer to a multiplication) and in design (something made) — and write a sentence for each.
- Write a glossary entry for "condense" without looking at the mini-glossary, then compare it with the real entry.
- Collect five academic words from today's math lesson instructions and write a meaning for each.
Exit ticket
"Rain helps seeds develop into tall plants. Seeds need precipitation to grow." Sort "develop" and "precipitation" as subject or academic words. What does each mean in its sentence?
What to look for: Develop: academic, grow or change bit by bit. Precipitation: science, water falling as rain, snow or hail. Both sorted as subject words: the math-lesson test is not yet a habit. "Develop photos": a remembered meaning not swapped into the sentence.

Questions about Academic and Domain Words
How long does the Academic and Domain Words lesson take?
40 minutes, split across 5 timed sections: warm-up 5 min, teach 13 min, guided practice 12 min, independent practice 8 min, close 2 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.
Which standard does Academic and Domain Words teach?
CCSS.ELA-LITERACY.RI.3.4 — RI.3.4, Reading: Informational Text for Grade 3: “Determine the meaning of general academic and domain-specific words and phrases in a text relevant to a grade 3 topic or subject area.” In plain terms, work out what a subject-specific word means in this text.
What do I need to teach this lesson?
"The Water Cycle" (five sentences, below), displayed and one copy per pair, a mini-glossary: evaporate, water vapor, condense, precipitation, eight warm-up word cards and two sorting columns: Subject words, Academic words and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.
What mistakes should I expect in this lesson?
Three, each a reasoning error rather than carelessness: puts "compare" and "describe" in the subject-words column; searches the glossary for "process," finds nothing and leaves it blank and says "form" in "drops that form clouds" means "a sheet you fill in.". The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.
How do I know whether the lesson worked?
The exit ticket asks: “"Rain helps seeds develop into tall plants. Seeds need precipitation to grow." Sort "develop" and "precipitation" as subject or academic words. What does each mean in its sentence?.” Develop: academic, grow or change bit by bit. Precipitation: science, water falling as rain, snow or hail. Both sorted as subject words: the math-lesson test is not yet a habit. "Develop photos": a remembered meaning not swapped into the sentence. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
Is there a worksheet to go with Academic and Domain Words?
Yes — 1 printable RI.3.4 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.
Is Academic and Domain Words free to use?
Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on October 8, 2026. Please do not resell it or republish it as your own.
