Trialed using a late slip for students who couldn't hand in assessment or a project on time. I find that you can spend much time in conversation with students explaining why they cant hand a piece of work up and when they will be able to hand it up.
I came across this idea many years ago - I believe maybe at a Bill Rogers talk....or some other PD I went to.
If is a small form that students fill in stating their reason and when you expect to receive it. The pros about this is that it is like a receipt. It also means their explanation is in writing and this can be referred to in Parent Interviews. I haven't really had an opportunity to use them before, but have found it useful recently. They are handy just to have some blank copies in your folder ready to go.
