One and Ones: Choosing Without Repeating
By the end: I can use one and ones instead of repeating a countable noun.
Try the activities, then check your answers.
Start here
Imagine choosing between two bags in a shop.
Read each explanation, say your answer aloud, then open the model and try again. You may write your answer if you prefer. Use invented personal details whenever you like.
Useful preparation: Singular/plural countable nouns, demonstratives and simple adjectives; basic comparatives are optional support.
Allow a first attempt before opening the model. Start: 3 minutes. Learn and You say: 18. Practice: 8. Listening: 9. Quiz and correction: 8. Speaking: 11. Recap: 3.
Choose a play button when you are ready.
One replaces one countable thing
Use one when a singular countable noun is already clear: Which bag? The blue one. One means bag here. Keep the adjective before one. This one and that one can also identify a single object.
I like the blue one.
That one is mine.
Choose from the two bags in the recording
“I want the blue one.” Here, one replaces bag. The colour identifies the bag the speaker wants.


Ones replaces plural things
Use ones instead of a plural countable noun: Which shoes? The black ones. Match is or are to the meaning: The blue one is small. The blue ones are small.
I like the black ones.
The small ones are in this box.
With plural shoes, use ones
Ones replaces shoes.
The colour distinguishes the two pairs.
Replace the noun and keep the size and place
Boxes introduces the plural noun.
Ones refers to boxes; are agrees with the plural.
Ask which one or which ones
Ask Which one? for a single object and Which ones? for plural objects. Use one/ones only when a countable noun is clear. It does not replace uncountable milk itself; name a bottle or carton if that is the thing you mean.
Which one do you want?
Which ones are yours?
