File this term's under 'bin' in the holidays. Like you say, no point marking them now. For next time read out the answers immediately at the end and get the children to self or peer mark. Then file their own sheets in a folder or book. Then in July they file the folder under 'bin' in their own house. I'd never have bothered with all the AF nonsense! But yes it does sound like the sort of thing I would think I 'ought' to do as well.
