Never smile until Christmas

Googeldades eile "rules for classroom" leidsin sellise kirjatüki:Many teachers make the mistake of starting the school year with a poor discipline plan. Students quickly assess the situation in each class and realize what they will be allowed to get away with. Once you set a precedent of allowing a lot of disruptions, it can be very hard to start better classroom management and discipline techniques. However, it is never tough to get easier as the year goes on. While you don't have to follow the adage, "Never smile until Christmas," it does have its merits.
