While in every-day, spoken English, 'amount' and 'number' may be interchangable, this is not true in Academic Writing.
There is no synonym for the word 'number', just like there is no synonym for the word 'children'. IELTS Writing checks if you can use paraphrase, which is not exclusively limited to using synonyms. Paraphrase is an element of writing that helps make the content more progressive and coherent, rather than repetitive and mechanical.
