Usually the children start acting up when they are done/bored of eating. Since children really enjoy listening to stories, you might want to have a teacher or principal tell an entertaining story towards the end of the lunch period. You also maybe could ask trivia questions once in a while instead of a story. It could be on the Parsha, Yom Tov, Halacha ect. This facilitates learning in a relaxed atmosphere and also captures the students' interest.
All of this depends on size of the group eating lunch and the various ages.

On March 6, 2012 a History Timeline of Purim was added to the Chinuch.org materials. It was contributed by the St. Louis Teachers\' Center and created by Dena Granick. A graphically appealing poster with the events of Purim clearly outlined in Hebrew- it\'s a great teaching tool for your classroom.

Wow, sounds like a great idea! The Walder Education Pavilion of Torah Umesorah is currently working on a multilingual feelings program. You can contact them at teacherscenter@waldereducation.org to see what they have available or perhaps they can recommend some great resources.

I would recommend using Microsoft Publisher. Since it is a Microsoft program, it is setup like Microsoft Word and very user friendly. It\'s not exactly a graphic design program, but it was programmed to create appealing documents and therefore has many visual add-ins.

Divide a section of the classroom into a few parts. (You can divide it with materials that would be used for each center- like bookshelves.) Think of centers that the children can use by themselves with a little monitoring- library, house, blocks, coloring ect. Once in a while you can create a special center- like water or rice tubs. These special centers should be part of your classroom curriculum and should be done in small groups with teacher supervision. Either create center time and/or when the children come in they can play at the centers.

How does one deal with students that have negative attitudes? Should I ignore them or should I answer their remarks in a positive way? Does anyone have any tips?
