This one page could save you HOURS of marking time! Instead of repeatedly writing the same things in lots of books, just write a number. Display the slide in your next lesson and ask them to correct their work. They will have responded to your feedback and shown progress, when all you have done is write a few numbers next to their work. If you really want to be sure they have read the feedback, ask them to copy it and tick off the ones they have corrected. Easy peasy! Enjoy!
