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. Objective: Recognize and analyze a conditional statements
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. Kfed: you give Kfed money he makes and awesome album Hypothesis-
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. * TRUTH VALUE?
Conditional- If a figure is a square, then it has four sides.
Converse- If a figure has four sides, then it is a square.
* Not all four sided figures are squares. Counterexample: Rectangles also have four sides.

9. Rewrite the statement as a conditional statement, then find the converse.
All teenagers are lazy.
Conditional-
Converse-
If you are a teen, then you are lazt.
If you are lazy, then you are a teen.

10. 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.

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

12. 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.

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