About this skill
A prefix goes at the start of a word and changes its meaning. Knowing prefixes helps children work out unknown words.
How to teach it
- Use each new word in a sentence out loud.
- Revisit words over several days — spaced practice beats cramming.
- Link new words to ones the child already knows.
Mistakes to watch for
- Memorising definitions without using the word in a sentence.
