Hi, I'm surprised you even teach third grade. In my school every single scrap of time is dedicated to the textbook and getting them through that exam. Given the opportunity, it sounds like a very kind and useful thing for them. All I can say is MAKE SURE EVERYTHING YOU TEACH THEM IS ACCURATE AND IN LINE WITH THEIR TEXTS AND THE TEACHINGS OF YOUR COTEACHER. The last thing you want is to have to backpedal over an example or explanation you gave.
Always give examples. Suggest certain sentence structures and pass out worksheets with the same information. It may be review for the more advanced students, but especially for the struggling students it will be a lot easier for you to point to the board when they just stare at you like you're speaking gibberish.
Thank you for all your suggestions! :) I really appreciate it.Actually, I was thinking about using High School Musical as the theme for all my classes. Every class, students will watch about 10 minutes of the movie and then based on the clips, we will have a themes (first day of class, extracurricular activities, etc), vocabulary and slangs that we can disucss about. Maybe some times I will have games to go along. What do you think?
