Set up the interactive whiteboard by connecting it to a computer in your classroom. Once properly assembled, the interactive whiteboard system will display what you see on your computer screen on your large classroom whiteboard.
Choose the topic about which you want your students to think critically. The best way to learn critical thinking skills is to apply them directly to a concept. These skills can be used on subjects ranging from literature to mathematics.
Display online resources such as news articles, quizzes or videos as prompts that encourage the students to think further about the subject. This could include analyzing the information or using it for a springboard discussion about other issues.
Encourage students to share their ideas with the class. Use your dry erase markers to supplement the information on the whiteboard. This will help drive home concepts and reinforce what you are trying to teach.
