My name is Tim Brzezinski, and I am middle and high school mathematics teacher at the Engineering and Science University Magnet School (ESUMS) in New Haven, CT. I am also a part-time independent mathematics education consultant (Brzezinski Math = https://www.brzmath.com/). I also served as GeoGebra's former Professional Development Director. Learning mathematics can be very engaging and fun for students, and my hope is this channel serves math teachers and their students with engaging content that helps promote intellectual curiosity, discovery learning, and promote active student engagement with exploring mathematics. I wish you much success on your mathematics teaching and learning journeys!
