We've been reading a couple of books on collective nouns here and there. Through these books such as the one above, N learnt that words like 'sheep', 'fish' have no plural erm, words? He also learnt that the plural for words like 'mouse' is 'mice', 'child' is 'children'.
As a follow up to what we have read, i prepared some word cards, one set on collective nouns and another set on animals. I place one set on one side and the second set randomly on the other side.
N matches them accordingly.
