Grade 5 · Reading · Lesson 7

Play word-building challenges

Big words are not magic — they are built. Most long English words are made of three pieces snapped together: a PREFIX (front), a ROOT (middle), and a SUFFIX (end). When you can spot the pieces, even a scary-looking word like DISAGREEMENT or UNLOCKABLE breaks open in seconds. Word-building challenges turn this into a game.

What this lesson teaches

1Combine a prefix, root, and suffix to build longer words
2Recognize how each prefix or suffix changes a word’s meaning
3Spell built words correctly when parts are joined
4Use newly built words in clear sentences
