  2. Today’s plan • Greeting • Mathematical Writing: Review Conjectures • (Return Journals, etc.) • Transformations: Formal Definitions • Homework / Questions • Clean-up

  3. Conjectures: Evaluation • Five groups: • 1, 6, 11, 16, 21 • 2, 7, 12, 17, 22 • 3, 8, 13, 18, 23 • 4, 9, 14, 19, 24 • 5, 10, 15, 20, 25 • Evaluate your five numbered conjectures according to the rubric. • 10 minutes.

  4. Conjectures:Evaluation of Evaluations • Get together with the others who evaluated the same conjectures as you. • Compare your ratings. • Disagreements? Justify your own ratings. • Decide as a group which rating to give each conjecture.

  5. Conjectures:Compare and Choose • Get together in groups of five (1, 2, 3, 4, 5). • Compare the conjectures you evaluated. • Are any of them saying the same thing? • Which ones say it best? • What is best about them? • Optionally, add the best conjectures to your log.

  6. Clean-up / Reminders • Pick up all trash / items. • Push in chairs (at front and back tables). • See you tomorrow!
