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

Keep a Lookout:

Try it on your ownTry it on your own

Work out the problem independently as we will take a class poll for the answer

Work together from the get-go

Work out the problem independently & then share your work with your partner

Learning Goal #4: LOGICObjective: Recognize and analyze a

conditional statements

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.

Hypothesis and Conclusion

• If it is sunny outside, then it is hot.

Kfed:

• If you give Kfed money, then he makes an awesome album.

– Hypothesis-– Conclusion-

you give Kfed money

he makes and awesome album

• 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.

NO HOMEWORK FOR A MONTH!• 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.

When you negate the hypothesis and conclusion of the converse of a conditional statement, you form the contrapositive.

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.

Sum it up for us:

Conditional statement

Converse

Inverse

Contrapositive
