Formative Assessment Classroom Challenges are aligned to the Common Core State Standards. Students in Kamaljit Sangha's middle school math class were learning about geometry when she incorporated this challenge on length and area. The lesson helps students reason abstractly and quantitatively, construct viable arguments, and critique the reasoning of others while addressing the mathematical concepts of length and area. This video presents different phases of the lessons and activities in context and includes excerpts of discussions between Sangha and the school's math coach, Sally Keyes.
