Word Surgery
- 1Write a word on a strip and cut off the prefix and suffix physically.
- 2Ask what's left in the middle — the root — and what it means alone.
- 3Build new words from the same root: help, helpful, helpless, unhelpful, helper.
- 4Make a silly word with real parts — "unbreakfastable" — and have them define it.
- 5Keep a running wall list of prefixes with their meanings.
If it's too hard
One prefix a week, applied to five known words.
If it's too easy
