4th Grade Vocabulary Words: 120+ Words With Meanings, Sentences and Stories
Fourth grade is when reading changes. Children stop learning to read and start reading to learn. Textbooks, chapter books and test questions suddenly fill up with words like evidence, predict, habitat and reluctant. A child who knows these words reads faster, understands more and writes with more confidence.
Below are more than 120 vocabulary words for 4th graders, grouped so they are easy to teach: describing words, action words, feelings, science and nature, and the "school words" that appear in every subject. Each has a meaning a 9-year-old can understand and an example sentence. Click any linked word to read a short illustrated story built around it. Children remember a word far better after meeting it in a story.
In the UK, 4th grade is roughly Year 5 (ages 9 to 10). The same list works for Year 4 and Year 5 pupils.
How to use this list
- 5 words a week is plenty. That is 180 words across a school year.
- Read, say, use. Read the word's story, say the word aloud, then use it in a sentence that day.
- Revisit. On Friday, ask your child to explain each word in their own words. A word is learned when they can use it, not when they can spell it.

Frequently asked questions
How many vocabulary words should a 4th grader learn each week? Around 5 to 10 new words a week is realistic. Five words learned deeply, so the child can explain and use them, beats twenty words memorised for a spelling test.
What reading level is 4th grade? Most 4th graders (ages 9 to 10) read chapter books and non-fiction texts with many subject words. That is why words like evidence, habitat and summarize matter so much at this age.
What is the best way to teach vocabulary to a 9-year-old? Let them meet words in context first, through a story or a book, then talk about the meaning and use the word straight away. Repetition over several days makes the word stick.
Is 4th grade the same as Year 5? Roughly. A US 4th grader (age 9 to 10) is the same age as a UK Year 5 pupil, so this list suits Year 5 well. It also stretches confident Year 4 readers.
Where can my child practise these words? Every linked word above opens a short illustrated story on Vocabulary Stories, and the app adds quizzes so children can check what they remember.
