About this activity

Eight long sentences reduced to their core: the very tall, friendly dog that lives next door ran quickly across the big green yard becomes the dog ran across the yard; my grandmother, who loves to bake, made a chocolate cake for my birthday party becomes Grandma made a cake; the loud thunderstorm that started after dinner knocked out the power on our whole street becomes the storm knocked out the power.

How to use it in a session

Ask what the sentence is fundamentally saying rather than which words to cut. Who did what to what is the question, and the answer produces the core sentence without any decisions about deleting. This is the reverse of expansion and it is genuinely useful for a student who loses the thread of long sentences in reading — finding the main clause is how a complex sentence becomes readable. Ten minutes covers the eight.

What to listen for

Watch whether the main verb is retained. A student who reduces to the dog next door has kept a noun phrase and lost the sentence, which shows they are cutting words rather than finding the proposition. Notice the sentence with an opening phrase — on Saturday morning — since students often keep the first words out of habit rather than importance.

Carrying it home

Long sentences in reading are the material. Asking who did what, when a sentence gets tangled, is a five-second comprehension rescue that works on any text.

Questions

What grades is this for?
Third through fifth, and it is particularly useful for students who lose the thread of long sentences.
Is it free?
Yes, all eight sentences play with no account.
Why practise reducing rather than expanding?
Because reading requires it. A student who can find the main clause in a long sentence can understand it; one who cannot gets lost in the modifiers, which is a common and fixable comprehension problem.
