About this activity
Ten sentences shown active and passive: the dog chased the ball becomes the ball was chased by the dog; mom baked the cake becomes the cake was baked by mom; the wind blew the leaves becomes the leaves were blown by the wind; lightning split the tree becomes the tree was split by lightning. The transformation moves the object to the front, which is what makes passives hard to understand as well as to produce.
How to use it in a session
Ask who did it after every passive sentence. Comprehension is the real target — students meet passives constantly in textbooks and misread who acted — and producing them is secondary. Cover the passive version and let the student build it, then check. The wind blew and lightning split are the two with irregular past participles — blown, split — and are worth doing last.
What to listen for
Listen for reversed agents in comprehension. A student who reads the ball was chased by the dog and says the ball chased the dog has taken the first noun as the actor, which is the default strategy and the reason passives cause comprehension failures. Watch the past participle, which is where production errors cluster: was blew rather than was blown.
Carrying it home
Passives are everywhere in written instructions and news. Asking who did it, when a passive comes up, is a five-second comprehension check with real transfer.
Questions
- What grades is this for?
- Fourth through seventh, where passives appear regularly in academic text.
- Is it free?
- Yes, all ten pairs play with no account.
- Should students produce passives or just understand them?
- Understanding is the priority. Passives are common in textbooks and rare in speech, so comprehension has the higher return — production practice mainly serves to make the structure visible.
