These Differentiated Centers of Triangles Task Cards are designed for classroom use in pairs, small groups, or by individuals. They are a great way to differentiate instruction as they have multiple difficulty levels. The first examines student knowledge of vocabulary regarding the various segments and their points of concurrency, the second level requires students to visually identify various points of concurrency, lastly, students are required to solve problem using the knowledge they have gained. The task cards come with QR codes embedded to allow students to use personal devices, if you wish, to check their answers. A second set of task cards is provided without the QR codes, if you prefer these. For your further convenience, a student answer sheet master is provided. The cards are suitable for laminating for many years of use. Also included is a teacher answer key.
