Vocabulary in Primary School: How Parents Can Help

Vocabulary is the knowledge children have about words and their meanings. It includes words they understand when listening or reading, called receptive vocabulary, and words they use when speaking or writing, called expressive vocabulary. Children also develop depth of knowledge, such as a word’s different meanings, associations, grammatical roles and meaningful parts.

Vocabulary matters because children need word knowledge to understand classroom explanations, discuss ideas and make sense of texts. It is one part of reading comprehension, alongside accurate word reading, fluency, background knowledge, language comprehension and the demands of the text. Teaching vocabulary can improve knowledge of taught words. Transfer to broad standardised comprehension measures is usually smaller and less consistent, so vocabulary practice should sit within a complete approach to oral language and literacy.

How vocabulary develops

Children learn many words incidentally through conversation, play, reading and learning across subjects. They also benefit from explicit teaching of selected words. Effective instruction does more than provide a dictionary definition. It connects a word with familiar ideas, examples, non-examples, word parts and repeated opportunities to understand and use it.

Vocabulary varies across families, cultures, interests and languages. A child may know sophisticated words about sport, music, Country, technology or family life that are not captured in a classroom task. Multilingual children build knowledge across languages. Using and developing the home language supports communication, identity and family relationships. Learning English should not require families to abandon the language they use most naturally and richly.

Choose useful words

A common teaching framework describes three broad tiers:

  • Tier 1: everyday words that many children learn through ordinary interaction, such as shirt or happy.
  • Tier 2: useful words that appear across school subjects and written texts, such as contrast, reluctant or consequence.
  • Tier 3: specialist words linked with a topic, such as photosynthesis or denominator.

These tiers are a selection guide, not a fixed universal list. A word that is familiar to one child may be new to another. Choose words that help the child understand a current text, topic or conversation and that are likely to be useful again.

Teach a word richly

Try a short sequence rather than asking a child to memorise a definition.

  1. Say and show the word. Pronounce it clearly and show it in print.
  2. Give a child-friendly meaning. “Reluctant means you are unsure and do not really want to do something.”
  3. Use it in context. Connect it with the book, lesson or situation in which it appeared.
  4. Explore examples and non-examples. Ask which situations show the meaning and why.
  5. Notice word parts. Link roots, prefixes and suffixes when they help, such as predict, prediction and predictable.
  6. Use it actively. Invite the child to complete a sentence, explain a choice or use the word in a new context.
  7. Return to it. Revisit the word over following days and weeks in speech, reading and writing.

There is no evidence-based number of exposures that guarantees learning for every word and child. Concrete words may be learned quickly, while abstract words with several meanings require more varied encounters. Review should respond to what the child remembers and can use, rather than a rigid quota.

Use morphology to unlock word families

Morphology is the study of meaningful word parts. In unhelpful, the prefix un- changes the meaning of help, and the suffix -ful creates an adjective. Older primary school children can use roots, prefixes and suffixes to infer meaning, connect related words and support spelling.

Keep this practical. Ask, “What part do you recognise?”, “What does the prefix change?” and “Can you think of another word in the same family?” Morphology is a useful component of literacy teaching, not a replacement for phonics, reading connected text or learning word meanings in context.

Read and talk together

Shared reading creates opportunities to meet words in meaningful sentences. Pause for a word that matters to understanding, give a brief explanation and continue the story. After reading, return to one or two useful words. Too many interruptions can make reading feel like a test and reduce comprehension and enjoyment.

Rich conversation also matters. Discuss how something works, compare characters, explain a recipe, recount an event or wonder about a new topic. Use precise words naturally, then explain them when needed. Open questions such as “What makes you think that?” encourage children to organise ideas and draw on vocabulary without requiring a polished answer.

A practical weekly routine

Choose a small group of words from school learning, a book or the child’s interests. The number should fit the child and the available time.

  • First encounter: explain the word, connect it to the text and discuss an example.
  • Word detective: notice the word, a related word or a meaningful word part during the week.
  • Compare: sort examples and non-examples, or compare the word with a near synonym.
  • Create: use the word in a sentence, drawing, short explanation or story.
  • Review: ask for the meaning in a new context and decide which words need more practice.

Keep correction specific. If the child’s use is partly right, acknowledge the accurate part and refine it: “You have the idea that it means angry. Furious usually means extremely angry.” Avoid praising advanced words merely because they sound impressive. The goal is accurate, flexible communication.

Support multilingual children

Talk, tell stories and read in the language in which the family can offer the richest interaction. Discuss how an idea is expressed across languages and notice shared or different word parts when this is meaningful. A child may know a concept in one language before learning the English label.

Vocabulary differences caused by learning more than one language are not, by themselves, a language disorder. Assessment should consider all languages used, opportunity to learn, cultural and educational experience and change over time. Families can ask whether a school or clinician uses culturally and linguistically responsive assessment practices.

Work with the school

Ask which words and topics are being taught and how the school expects children to use them. Share what helps the child remember and communicate. If a child struggles to understand instructions or texts, clarify whether the main difficulty involves word reading, vocabulary, broader oral language, attention, working memory, hearing, background knowledge or a combination.

Home practice should reinforce school learning without recreating a long lesson after a tiring day. Five focused minutes in conversation or reading may be more useful than a large worksheet completed with conflict.

When to seek further advice

Speak with the teacher if vocabulary or language difficulties are persistent, increasing or affecting reading comprehension, writing, classroom participation or friendships. Ask what has been observed, which teaching has been provided and whether the child is progressing with support.

A GP, audiologist, speech pathologist or psychologist may be involved depending on the pattern of concern. Hearing should be considered when a child frequently misses spoken information. A speech pathologist can assess oral language, while a psychologist may explore learning, attention and broader development. Assessment should answer a clear question and integrate history, observation and information from home and school rather than rely on one vocabulary score.

What the evidence can and cannot tell us

Meta-analyses and systematic reviews support explicit, active and repeated vocabulary instruction, particularly for learning directly taught words. Effects vary by age, learner group, teaching approach and outcome measure. Some studies concern English learners in settings outside Australia, and many interventions are delivered by trained educators rather than parents.

This means families can use the principles of clear explanation, meaningful context, active use and review, while avoiding claims that one word list, number of exposures or commercial program will suit every child. Progress is best judged by whether the child increasingly understands and uses useful words across real tasks.

How Quirky Kid can help

The Increasing Focus and Managing Attention workshop may help adults build routines that support engagement with learning. Tell me a Story provides prompts for oral language, imagination and family storytelling.

If persistent language, reading or learning concerns are affecting your child, explore educational assessments or contact Quirky Kid to discuss an appropriate next step.
