dear friends, 

here is a shot from the  presentation SCHOOL RULES

mind the cliches that can help you express the  ideas:

=a student must/should...

=it is not allowed to...in school

=never...while at school

=come on time, do homework in time

=respect smb, keep the rules, obey the regulations

=...smoking is strictly prohibited (запрещено)

= chewing gum (жевательная резинка), MP3 player, mobile phone

=a record-book, an exercise book, a textbook (a student's book), 

=a cloak room (гардероб), change shoes (сменная обувь), 

=to organize the  working place, to look tidy, to behave one's age

=with the purpose to..., with the intention of...ing (с целью)

Good luck, see you on Monday and Tuesday (respectively)
