Mr. Ott (@iteach_kidsmath) was a student teacher in my classroom this past fall semester. He was great with the students, very receptive to feedback, and open to new ideas.
Now that he has his own classroom, it's cool to see him continue to grow as an educator. He has fully embraced the power of twitter as a tool for professional development and collaboration. He has also begun to blog about his experiences in the classroom.
Keep up the great work, Mr. Ott. We're glad you're going strong!
