Geometry assignment; 10/22

We worked through 4 different review examples today before starting on the chapter 3 review packet.  The students then spent the last half of the period finishing the review packet and preparing for the test tomorrow.

Assignment:  Chapter 3 review packet

Inductive and Deductive Reasoning Page

1.  Inductive reasoning;  based on a repeated pattern of experiences
2.  Deductive reasoning;  based on a single fact that her father told her earlier
3.  Deductive reasoning;  based on a single fact that the teacher had stated about showing no work
4.  Inductive reasoning;  based on observation of paycheck patterns and early projects completed
5.  Inductive reasoning;  a pattern of different ties is observed and a conclusion is made as a result
