Year 3 Prefixes Worksheet Set – un-, in-, dis-, mis- and re- (919-921)
This Year 3 prefixes worksheet set helps children practise using five common prefixes: un-, in-, dis-, mis- and re-. Pupils learn that some prefixes mean “not”, while others change the meaning of a word in different ways, such as “wrongly” or “again”.
The worksheets are carefully differentiated across three levels: Triangles, Circles and Squares, making them suitable for mixed-ability classes, homework, tutoring or revision. Each sheet builds children’s confidence with prefix meanings before moving towards applying prefixed words in sentences.
Children will practise words such as unhappy, incorrect, dislike, misread, replay, unsafe, incomplete, disagree, rewrite, rebuild, misplace and disappear.
This resource is ideal for strengthening spelling, vocabulary and word-building skills in Lower Key Stage 2. It also supports the type of word knowledge children need for later reading comprehension, grammar and spelling work, including preparation for KS2 SATs and vocabulary-style questions similar to those seen in NAPLAN.

Differentiation
Triangles focus on identifying prefixes, matching prefix meanings, adding prefixes to root words and choosing the correct word in simple sentences.
Circles extend this by completing sentences with prefixed words and matching definitions to words such as misspell, unsafe, rewrite, incomplete, misread and disappear.
Squares provide a greater challenge with more independent sentence completion, definition work and sentence writing using words such as incorrect, misunderstand, disappear, rewrite and unusual.
