Tier 2 and Tier 3 Vocabulary: Examples and Teaching

Tier 2 vocabulary includes words used across many written texts and subjects, such as consequence and establish. Tier 3 vocabulary includes specialist words, such as photosynthesis and isotope. These groups help teachers choose which words to teach directly.

The framework comes from Beck, McKeown and Kucan (2013). The authors describe tiers as a rough guide, with blurred boundaries. It is a planning aid, rather than a scale of learner ability. Knowing a familiar word also does not establish that a learner knows every subject meaning.

For a Year 8 history task about changes in towns, teach both urbanisation and consequence. Explain the new process and the language needed to discuss it. Do not delay a necessary subject term because a policy says Tier 2 words must always come first.

Use the whole-school vocabulary planning pack to choose words, prepare examples and record where they will be revisited.

Use three tiers to guide selection

The three tiers show how words tend to be used. Use them when you check a text, then decide what needs teaching. The examples below are starting points. Check the meaning needed in your lesson and what these learners already understand.

Vocabulary tiers and teaching decisions

Tier	Typical vocabulary	Teaching decision
Tier 1	Everyday words, such as table, run and happy.	Check familiarity. Teach directly when learners need the meaning.
Tier 2	Words useful across written contexts, such as consequence, reluctant and establish.	Explain the meaning and apply it in several relevant contexts.
Tier 3	Specialist terms, such as isotope, photosynthesis and feudalism.	Teach the term with its subject concept, then use it again.

In Year 4, table may refer to furniture or a way of organising data. A learner may know one meaning and need the other taught. Familiarity affects the teaching required; it does not make every known specialist term a Tier 1 word. High-frequency word reading is also a different decision from understanding a word's meaning.

Choose words from the next lesson

Start with the text, question or task. In a Year 5 water-cycle lesson, evaporation and condensation name processes learners must understand. Compare tells them what to do with that knowledge. Select a manageable set you can teach and revisit, rather than copying every unfamiliar word into a list.

• Needed now: does the lesson depend on this meaning?
• Already understood: can learners explain or use it in this context?
• Useful again: where will it appear later in the unit or another subject?
• Easily confused: does it have another meaning learners may bring to the task?

Check what learners know before you teach the word. Show two examples of compare: listing separate facts and finding a similarity or difference. Ask learners which response fits the instruction and why. This shows whether they know what to do, and links word teaching with reading comprehension strategies.

‍

Explain and practise Tier 2 words

Give an explanation using language learners understand. For consequence, say: “A consequence is something that happens as a result of something else.” Show a sequence: heavy rain, a flooded path, a cancelled walk. Ask learners to identify a consequence and explain its cause.

Add a non-example, such as opening an umbrella as the cause of rain. Ask learners to correct that relationship, rather than merely repeat the definition. The Frayer Model template separates meaning, characteristics, examples and non-examples. It is useful when the comparison reveals what a word includes and excludes.

For a Year 2 story, teach reluctant through a character who hesitates to join a game. Contrast that with someone eager to join. Ask learners to select a picture or describe the difference. During a later dialogic reading activity, return to the character's choice to provide another meaningful encounter.

Ask learners to apply consequence to a new event, as well as explain its meaning. Accept a labelled sequence, a spoken response or a written sentence when it shows the intended reasoning. For example, they can arrange rain, flooding and a cancelled walk in order, then explain one link.

‍

Teach Tier 3 words with the concept

In Year 8 geography, demonstrate how moving water wears material away, then name erosion. Contrast it with material being moved and being left behind. Ask learners to label those processes and explain one difference. A polished definition without that distinction is an incomplete check.

Use a diagram to explain the concept. For photosynthesis, connect light, carbon dioxide and water with the production of glucose and release of oxygen. Teach learners how to read the diagram. When combining words and diagrams, show how each part of the drawing links to the explanation.

Point out word parts when they help, but check the complete meaning. Photo relates to light; that clue alone does not explain photosynthesis. Record an accurate definition and worked example in a curriculum knowledge organiser. Return to the term during explanations and subject questions.

Try a short word-family routine by showing predict, prediction and predictable in sentences from the unit. Identify the base they share, then explain how the endings change each word's job.

Ask learners to choose the form that fits a new sentence and explain what it means. Word parts give clues, so check them against the full sentence.

Worked lesson: words in Year 5 science

A short vocabulary plan can include technical words and the language needed to use them. For this water-cycle lesson, select evaporation, condensation and compare. The first two name processes, while the third tells learners how to relate them. These steps are teaching examples, rather than a tested intervention.

‍

Prepare clear meanings and examples

Explain evaporation as liquid water changing into a gas. Explain condensation as water vapour changing into liquid water. Match evaporation to a wet cloth drying, and condensation to drops forming on a cold mirror in a steamy bathroom. Keep each example beside its meaning.

Ask learners which process explains each observation, and why. If they think evaporation always means boiling, return to the drying cloth. If they think the mirror produces water, trace where the water vapour came from. Use the response to choose the next explanation.

‍

Teach the instruction as well

Model what compare asks learners to do: “Both processes involve water changing state. Evaporation changes liquid water to a gas. Condensation changes water vapour to liquid water.”

Underline the shared feature, then the difference. Learners can rehearse the comparison using two labelled arrows. A later question can show a drying puddle and water drops on a cold surface. Ask learners to name and compare the processes.

A response that only defines evaporation needs a prompt to include condensation. Correct spelling alone does not show that the comparison is understood.

‍

Worked lesson: words in Year 8 history

In a lesson about industrial towns, combine a subject term with a word used for reasoning. Teach urbanisation and consequence together, then ask learners to explain a change using the unit's evidence. This keeps Tier 2 and Tier 3 teaching connected to the same history task.

‍

Keep the subject meaning precise

Explain urbanisation as an increasing share of the population living in towns and cities. This follows the United Nations demographic glossary. A town getting bigger is not enough evidence on its own. Compare information about where people live, rather than treating a picture of new buildings as proof.

Choose a short passage from the planned unit describing a change and an outcome. Retain its date and source details. Ask learners to mark the change, then the consequence described in the passage. Do not ask them to invent effects the text does not support.

‍

Check the link between ideas

Model a sentence structure: “One consequence of this change was… The passage supports this because…”. Learners complete it with information from the text. Ask them to explain why the second detail supports the first. Two vocabulary words in one sentence are not enough if the causal link is wrong.

Return to consequence with a different historical change later in the unit. Keep the reasoning demand, but change the example. If a learner explains a sound connection in everyday language, acknowledge that understanding. Then model how the new vocabulary can make the explanation more precise.

‍

Make meanings clear across subjects

Agree where each subject will teach and use shared words. In maths, evaluating an expression can mean calculating its value. In history, evaluating an explanation involves judging it using evidence. Show learners both tasks and name what they need to do in each, while keeping each subject's meaning clear.

The Education Endowment Foundation (2019) warns that a word can mean different things in different subjects. It highlights this in its secondary literacy guidance. Our guide to disciplinary literacy across subjects explains how vocabulary links to reading and writing. Agree who will introduce each meaning, where it will be used and when to check it.

Use the pack's word map for those decisions. If your school already uses Word Aware, connect the map to its routines. The Word Aware STAR approach explains that programme's structure. The shared pack supports planning; it does not replace programme materials.

Complete one row before extending the map. Record the word, its meaning in this subject, the first lesson and a later application question. For evaluate, keep separate maths and history entries. Give colleagues the actual task beside the definition, so the expected use is clear.

‍

Review vocabulary in ordinary classwork

Plan a later question that requires the meaning. After teaching consequence in history, ask learners to explain an outcome in a different part of the unit. A short retrieval practice task can check remembered meaning. Follow it with application, so a memorised sentence is not the only evidence.

After two weeks, review a few pieces of classwork with colleagues, with names removed. Check whether the word fits the subject meaning and whether the explanation makes sense. Record what to teach next when it does not. Choose a small word list you can revisit, and adjust it to what learners need.

‍

Fix common vocabulary teaching problems

Choose the next teaching action from the response, rather than adding the same support for everyone. In Year 5 science, a copied definition and a wrong process label reveal different needs. Check the idea, the example and the language separately. The examples below show how to respond.

‍

Definitions are copied without understanding

Show an example and a non-example, then ask learners to explain the choice. For condensation, compare drops forming on a cold surface with liquid water freezing. If the choice is wrong, revisit the change of state. Copying the definition again does not expose that difference.

‍

The idea is clear without the word

Accept “the water turned into a gas” as relevant understanding. Connect it explicitly to evaporation, then ask for another example. Give learners a chance to use the new term in speech or writing. Check accuracy before expecting a longer response.

‍

The word list is too long

Return to the next task and identify which meanings it depends on. In a comparison of two water-cycle processes, teach those names and the instruction word first. Explain other unfamiliar words as they arise. Plan later encounters with the selected words instead of rushing through a larger display.

‍

Limitations of vocabulary tiers

Word teaching is one part of reading instruction. Elleman et al. (2009) found stronger comprehension effects on custom measures than on standardised measures. Cervetti et al. (2023) found no overall positive effect on vocabulary breadth from the word-meaning interventions they reviewed. Do not treat success with a taught word as proof of broad reading improvement.

In practice, teach new curriculum language as an addition to learners' existing language. For example, accept “it wore away” as evidence of a relevant idea, then connect it to erosion. The tiers classify vocabulary use, not children. They also differ from the additional support levels described in a tiered support system.
