1. Title of Lesson: Patterns and Inductive Reasoning Section: 1.1Pages: 3-9

2. My Learning Goals 1.Find pattern and be able to justify the logic. 2. Use inductive reasoning to make conjectures. 3. State counterexamples to prove conjectures false.

3. Vocabulary/Formulas 1. Inductive Reasoning: Looking for patterns and making conjectures. 2. Conjecture: An unproven statement based on observations 3. Counterexample: An example that proves a conjecture false. 4. 5.

4. Prerequisite Skills with Practice 1.Evaluate:2.Approximate the square root without a calculator:

5. Notes Finding pattern based on observations. Mobius Strip Activity.

6. Notes Text: Inductive Reasoning- 1.Look for a pattern 2.Make a conjecture 3. Verify the conjecture Problem If this pattern continues, how many squares will be in the ninth figure?

7. Notes Text: More inductive reasoning Problem How many suns in the eighth figure?

8. Notes Text: More inductive reasoning Problem: How many moons in the tenth figure?

9. Notes Text: Counterexamples prove conjectures wrong. Only a single counterexample is needed to debunk a conjecture. Problem: Conjecture – “All prime numbers are odd.” Counterexample - Conjecture – “All birds can fly.” Counterexample -

10. Notes Text: More counterexamples Problem Conjecture – “The square root of x is always less that x. Conjecture – All dinosaurs were green.
