At Hart, nearly all math students participate in Teach to One, which is housed in retrofitted classrooms in the school’s basement. When you walk in, the first thing you notice is the noise. There are the equivalent of about four classrooms of students in each of two Teach to One rooms, but no physical separations between them. Joel told us his team finds when students are engaged in solo or small group work, they hardly notice the commotion; special noise-mitigating carpets and ceiling panels are also used.
