Work in pairs. Practise the dialogue.
Sammy: I’m looking for jewellery for my mum. What do you think of this pendant? It’s real gold.
Grace: Oh, it’s nice, but it’s quite small.
Sammy: I like the size of it, but it’s a bit too expensive.
Grace: Wow! It’s, like, £70! I mean, it’s not as nice as that silver one.
Sammy: Oh yes, I much prefer that one. It’s Mum's style.
Sammy: OK, let’s see. Right, the silver one is much less expensive. It’s only £30.
Grace: Well, get that one then.
