1. 10/2/2014 Foundations:basic logic, writing skills Essential Question: What are the elements of a conditional statement? What is a converse? What does conditional mean? Homework:If-then Comic Strip Analysis

2. Keep a Lookout: Work out the problem independently as we will take a class poll for the answer Work out the problem independently & then share your work with your partner Work together from the get-go

3. Learning Goal #4: LOGIC Objective: Recognize and analyze a conditional statements

4. Conditional Statements • Called “if-then statements.” • Hypothesis- The part following if. • Conclusion- The part following then. * Do not include if and then in the hypothesis and conclusion.

5. Hypothesis and Conclusion • If it is sunny outside, then it is hot. Truth Values?

6. you give Kfed money • he makes and awesome album Kfed: • If you give Kfed money, then he makes an awesome album. • Hypothesis- • Conclusion-

7. The converse of a conditional statement is formed by exchanging the hypothesis and the conclusion. • Conditional- If it is sunny outside, then it is hot. • Converse- If it is hot, then it is sunny outside.

8. NO HOMEWORK FOR A MONTH! NOT! • When you negate (“not”) the hypothesis and the conclusion of a conditional statement, you form the inverse. Example: Cond. Stmt: If is sunny outside, then it is hot. Inverse: If it is NOT sunny outside, then it is NOT hot.

9. When you negate the hypothesis and conclusion of the converse of a conditional statement, you form the contrapositive. NOT!

10. Example: Cond. Stmt: If it is sunny outside, then it is hot. Converse: If it is hot, then it is sunny outside. Contrapositive:If it is NOT hot, then it is NOT sunny.

11. Sum it up for us: Conditional statement Converse Inverse Contrapositive
