Warm UP

On your paper write a story that connects the following streams of pictures. (1 sentence per picture)

What is a Proof?
• A proof is a convincing argument that something is true.
• In math, a proof starts with things that are agreed on.
• Properties
• Theorems
• Postulates or axioms
• Logic is used to reach a conclusion
How was the warm-up like a proof?
• The pictures are the “benchmarks” of the story.
• In a proof we call these the “statements”
• The sentences you wrote linked the pictures together to create a full story.
• In a proof we call these the “reasons”
What is a Proof?

Proof = Your Story (pic + sent.). Were your stories convincing argument for why those pictures are connected?

Did you use logic to connect your pictures or did you make up crazy fanciful stories?

Types of Proofs
• Some proofs follow a prescribed form and are called formal proofs.
• Two-column Proofs
• Paragraph Proofs
• Flowchart Proofs
• Coordinate proofs
• Table Proofs
Let’s turn our Warm up into a 2-Column Proof

Picture (Statement)

Sentences (Reasons)

• Timmy and his mom get in the car and start driving.
• Timmy’s mom takes him to the zoo where they see the elephants.
• After the zoo Timmy’s mom takes them to get ice cream.
P.O.E.’s
• P.O.E. stands for Property of Equality
• There is a P.O.E. for every operation
