LOVE THIS!! Check out the level of student engagement, the quick transitions, and the effective "check for understanding" at the end of the lesson. Fantastic! From YouTube: Watch Kristin DeWit, veteran Whole Brain Teacher, guide her class through a lively geometry lesson.
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! -by ⚛ Jen Siler's Classroom
