I believe that progressive learning of English is possible through fun interactions with the kids, but I never forget about discipline.
The definite article is only licensed if the noun is known to the speaker and listener. This can be done by
(1) general knowledge "The Moon is bright" - we are all aware of the Moon.
(2) previous reference (I saw a boy. The boy was tall) or postpositional reference "The boy was tall. Apparently, he was the son of the blacksmith."
The directs the listner's/reader's attention to a specific noun: one that is described or defined.
Without "the", "kids" = kids in general.
In your example, "the kids" indicate a specified group and the nature of that group must be known to both the writer and reader/listener.
In your example, you have not described any group, so "the" is wrong. Your audience would ask "Which kids?".
It may be that you have mentioned and defined/specified this group of kids in an earlier part of the speech/article if so then "the" would be appropriate.
