Throughout the year, math teachers work side-by-side with students to help them build their mathematical reasoning skills. We aim for each girl to learn at a pace appropriate for her, a pace that challenges her while giving her the time she needs to build enduring understandings. In the classroom, girls work individually and in collaboration to solve real-world math problems. Longer class periods allow for guided practice and deeper connections between former understandings and new concepts. During the middle school years, neurological development, exertion of effort and finding a teaching approach that works best for each girl are three forces that, in concert, lead to girls’ success in math.
