About this activity
Twelve sentences using when or while: when the bell rings, we line up; while she cooked, he set the table; while I was sleeping, it started to rain; when the game ends, we'll go home; while the dog barked, the mail carrier waited. The two conjunctions do different jobs — when marks a point in time and while marks a stretch of it — and students use one for both.
How to use it in a session
Sort by meaning before producing. The when sentences describe a moment when something happens; the while sentences describe two things happening at once. Asking which two things overlap makes while's job explicit, which is the harder of the two. Then flip the clause order — we line up when the bell rings — since students meet both orders in reading and produce only one. Ten minutes covers the twelve.
What to listen for
Listen for when standing in for while. When she cooked, he set the table is grammatical and loses the simultaneity, which is the whole point of the sentence. Watch the comma, which moves with the clause — a fronted clause takes one and a trailing clause does not, and that is a writing issue students meet immediately.
Carrying it home
Temporal clauses are easy to model. While I make dinner, you can set the table gives the structure and a real instruction in one sentence — and when the timer goes, we eat gives the other one just as cheaply.
Questions
- What grades is this for?
- Second through fifth, alongside other complex sentence work.
- Is it free?
- Yes, all twelve sentences play with no account.
- What is the difference between when and while?
- When marks a point in time — when the bell rings. While marks a stretch during which something else happens — while she cooked. Students commonly use when for both and lose the simultaneity.
