Simultaneous Roundtable Parallel Lines, Angles & Algebra - Advanced

Simultaneous Roundtable -- Parallel Lines, Angles & Algebra - Advanced

Materials:  one set of questions on transparency  one recording sheet and pencil per student

Procedures: 1. Students sit in teams of four and number off. 2. Teammate 1 writes problem 1 on his/her paper, Teammate 2 writes problem 2, Teammate 3 writes problem 3, and Teammate 4 writes problem 4. 3. Each teammate performs task 1, and passes their paper to the next teammate in a clockwise direction. 4. Each teammate checks the previous work, initials it, coaches and/or praises a job done well, and then performs task 2, and passes their paper to the next teammate in a clockwise direction. 5. Each teammate checks the previous work, initials it, coaches and/or praises a job done well, and then performs task 3, and passes their paper to the next teammate in a clockwise direction. 6. Each teammate checks the previous work, coaches and/or praises a job done well, and then performs task 4, and passes their paper to the next teammate in a clockwise direction. 7. At this point, each teammate should have his/her original paper back with the problem completely worked out. Each student should check all the work, and then sign the paper indicating his/her approval of all the work done. Simultaneous Roundtable -- Parallel Lines, Angles & Algebra Period _____
