This is a task on the concept of Proving a Quadrilateral is a Parallelogram.
This is a 6 page team task. In this task students will take turns as "Team Mathematician".
Students will determine if they can prove that the given quadrilateral is a parallelogram based on the given information? Explain.
Students will use color-coding, and answer guided questions to complete 2 two-column proofs on proving a quadrilateral is a parallelogram.
Students will make the given statement true using always, sometimes or never. Justify your reasoning.
* This task will have your classroom rich in mathematical discourse.
*** My "Team Tasks" are created to be completed in Teams of four. Each student is a team member: Team Member (A), Team Member (B), Team Member (C), and Team Member (D). Each team member is required to participate regularly throughout the "Team Task" as Team Mathematician. My cooperative learning "Team Tasks" require the students to be actively involved throughout the entire "Team Task". The Role of "Team Mathematician" alternates throughout the "Team Task". My "Team Tasks" are designed to elicit mathematical discourse within the teams.
Included are blackline masters. (There is no answer key. There are various answers that will be acceptable. This is a task rich in student reasoning).
