One little trick I have to help out the new intake is to give them batshit directions. Last year a small group of worried faces appeared at my lab door "...sir...we are looking for the chemistry lab..." - ah ha, no problem, grab a bit of paper, make a note - go back the way you came, down the stairs, left along the corridor, out of the double doors, across the courtyard, in the double doors, up the stairs to the fourth floor, along the corridor, down the stairs to the first floor, along the corridor, 5th door on the right.
Off they go, to which the technician comments that is an odd route to get to the room next door to the one that we are in.
This establishes 4 things, bonding between the group of 5 children who will almost certainly get lost, a working appreciation of the discipline system as they will be late (but let off because its only week one), a grasp of the labyrinthine school layout, and the fact that the bloke who teaches physics is a nutter!
All good.
Its amazing that by the end of week 2 all the little terrified year 7's are in the main well adjusted to, and enjoying secondary.
