Exit Ticket

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.

QUESTION 1
What does a prefix do?
It attaches to the beginning of a word and changes its meaning, like 'un-' making a word mean its opposite.
QUESTION 2
How can a suffix change a word?
It attaches to the end and can change meaning, part of speech, or tense, like '-ful' meaning full of.
QUESTION 3
How do affixes help you read?
Recognizing a known prefix or suffix helps you figure out the meaning of an unfamiliar word.

Create: build new words.

Have students pick a root word, add prefixes and suffixes to build new words, and define each one, so affixes become a tool for meaning. A printable prefixes-and-suffixes worksheet is in the English Language Arts library.
