It is important that in setting your timetable that you write it out every morning and timetable in everything, be that your breaks, a walk, reading time.
A timetable of your week’s activities is a good idea too, for both you and the pupils. On a Monday, I give an overview of the lessons we will be doing every day or activities with resources needed beside each one. If there is a specific requirement, especially for art, even if it is just to have toilet rolls collected, giving notice for this is a good idea. This also helps pupils get their own week timetabled and planned out and parents can work around this too.
