Can share how you get your P1 child to do homework and revisions while you are at work? I have tried so many monitoring methods and they do not work well with my boy.

Depend on the childs language of love. For my child it's gifts. I would give them tokens if they have done their homework or assessment books WELL (Not for doing only else they might just give me sloppy work)or full marks for tests. The tokens can be used to exchange for stuff.
