About This Worksheet
This Year 3 spelling worksheet helps students explore the prefixes un-, re- and dis-. Students practise noticing how a prefix can change or add to the meaning of a base word and use that knowledge when reading and spelling.
What Students Practise
- Identifying un-, re- and dis- at the beginning of words.
- Connecting prefixes with changes in meaning.
- Building new words from familiar base words.
- Applying prefix knowledge to spelling and vocabulary.
How to Use It
Read the base word first, then add the prefix and discuss how the meaning changes. Examples include happy → unhappy, write → rewrite and agree → disagree. Ask students to explain the meaning of the new word in their own words.
Parent Tip
Use everyday vocabulary to reinforce the pattern. When your child meets a new word beginning with un-, re- or dis-, pause and ask whether the prefix gives a clue to its meaning.
