For our poster-making activities, we also had some sessions with grades 1-3 students. During the sessions, we watched short movies, did presentations about misinformation, and guided them in making posters about how to avoid and stop misinformation.
We made a poster about 10 ways how to stop misinformation and those are verifying information, checking the source, encouraging critical thinking, being aware of your emotions, reporting false information, being cautious with social media, educating others, reading often, developing media literacy skills, and finally share information responsibly.
