KC Lawler (mathematics co-lead teacher) teaches mathematics at Loomis Chaffee in Windsor, CT. She has taught in boarding and day private schools in the US and one public school in Ghana where she was also the emissary to a small NGO. When not in the classroom, KC spends time with colleagues collaborating in Critical Friends Groups as the lead facilitator, writing problem-based curriculum with other math teachers, or working with peers to develop competency-based learning, grading, and assessing strategies. She loves watching her students light up as they co-construct their knowledge and understanding of mathematics with her and uses researched neuroscience to support her teaching and learning strategies in the classrooms. She is excited to be part of the Klingenstein Summer Institute and give back to a program she enjoyed so much herself so long ago. When not steeped in teaching and learning, she can be found cycling quiet New England roads, dabbling in writing poetry, gardening, upcycling junk to become useful objects, or playing with her mutt.
