For things like meal times I would provide props in the home corner like a washing up bowl, cutlery etc so the children can play at washing up after meal times, preparing play food etc. that could be a good lead-in to doing it for real. Also providing cooking experiences the chn can help with.
Hope this is of help.
Your idea for packing away is good - also by supporting & praising what they do right here will support the development of these skills.
