This is the only icebreaker that I use with my high school science students! I've used it for over 5 years and it is always my favorite day of the year. This icebreaker activity allows you to 1) talk science on day one 2) randomly group students for your seating chart 3) spend time getting to know your students and 4) allowing them to get to know you!
Guess Who? Cards are a simple time-filler activity for those times that you need to fill about 5 minutes before recess or lunch, or the end of the day. This activity also strengthens sense of belonging and community in the classroom. See this blog post for a brief explanation of how you can get started in your classroom.
