To make questions in the Past Continuous, use:

 

Was/Were + subject + the “-ing” form of the verb

 

Singular	Plural
Was I singing? Were you singing? Was he/she/it singing?	Were we singing? Were you singing? Were they singing?

 

Was it snowing yesterday at 5 o’clock?

Were you still skating in the park when Jemma called you?

Were the boys working in the garden when their uncle came round for a coffee?  

 

Note: in short positive answers to the Past Continuous questions we use only full forms of was/were. In short negative answers we can also use short forms of was/were.
