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 tell an academic word from a subject word and work out each one's meaning.
Students are successful when they can
- Sorts words into academic and subject-specific.
- Uses the right strategy for each kind.
- Gives a meaning that fits the sentence.
What you need
- A subject text with both kinds of vocabulary
- Two sorting columns
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — which subject?
5 min- Give eight words. Ask which subject each belongs to.
- Some belong to one; some turn up everywhere.
Teach — two kinds, two strategies
13 min- Name them: subject words belong to one topic; academic words turn up in every subject.
- Take a subject word. The text or the glossary will define it.
- Take an academic word — 'compare', 'describe', 'develop'. No glossary will have it.
- For those, the strategy is the sentence plus what you already know from other subjects.
- Say why academic words are harder: nobody teaches them explicitly and they matter everywhere.
“Nobody puts 'develop' in a glossary. You will meet it in every subject you take.”
Guided practice — sort and define
12 min- Pairs sort six words into the two columns.
- They define each with the right strategy.
- They check each meaning fits the sentence it came from.
Independent practice
8 min- Students complete the vocabulary page.
- The passage and a glossary are on the sheet.
Close
2 min- Give one academic word. Take a meaning and another subject it appears in.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Treats every unknown word as a subject word.
Why: Subject words are the ones flagged in bold and taught explicitly.
Fix: Ask whether it would appear in a maths lesson. Academic words would.
Looks up an academic word in the glossary and finds nothing.
Why: The glossary is where meanings live.
Fix: Sort first. The sort tells you which strategy to use before the search.
Gives a meaning that does not fit the sentence.
Why: A remembered meaning from another subject arrived first.
Fix: Substitute and read. Academic words shift slightly by subject.
If they are not there yet
- Give the sort.
- Three words rather than six.
If they finish early
- Find an academic word used differently in two subjects.
- Write a subject word's definition without the glossary.
- Collect five academic words from a maths lesson.
Exit ticket
Sort these two words. What does each mean here?
What to look for: A correct sort and two fitting meanings. Both sorted as subject words means the maths-lesson test needs asking each time.

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?
A subject text with both kinds of vocabulary, two sorting columns 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: treats every unknown word as a subject word; looks up an academic word in the glossary and finds nothing and gives a meaning that does not fit the sentence. 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: “Sort these two words. What does each mean here?.” A correct sort and two fitting meanings. Both sorted as subject words means the maths-lesson test needs asking each time. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.

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.
