TWISTERTWISTER
TWISTERTWISTER Directions: 1)Each student picks a circle with a color (red, blue, green, yellow) from a bag. 2)The teacher spins the spinner (either on Smartboard or homemade) and a color is revealed. 3)The teacher reads the first word of that color (yellow 1). Each yellow student has two minutes to write a definition of that word. 4)The teacher collects the definitions and reads them aloud without saying the student’s name. 5)The rest of the class votes on the best definition. The students get a point for each vote they get. 6)The students with the most votes after all words have been read is the winner.

TWISTER conclusion
Is the part of a conditional statement following the word then. back
TWISTER Paragraph proof
Paragraph proof Is a style of proof that presents the steps of the proof and their matching reasons as sentences in a paragraph back
TWISTER conjecture
Educated guess A statement you believe to be true based on inductive reasoning back
TWISTER inverse
Is the statement formed by negating the hypothesis and the conclusion back
TWISTER negation
The negation of a statement p is “not p”, written as ~p back
TWISTER Flowchart proof
Flowchart proof A second style of a proof which uses boxes and arrows to show structure back
TWISTER polygon
Polygon Is defined as a closed plane figure formed by three or more line segments back
TWISTER Conditional statement
Conditional statement Is a statement that can be written in the form of “if p, then q” back
TWISTER Inductive reasoning
Inductive reasoning Is the process of reasoning that a rule or statement is true because specific cases are true back
TWISTER contrapositive
Is the statement formed by both exchanging and negating the hypothesis and the conclusion back
TWISTER Truth value
A conditional statement has a truth value of either true (T) or false (F). False – when hypothesis is T and conclusion is F back
TWISTER polygon
Is defined as a closed plane figure formed by three or more line segments back
TWISTER Biconditional statement
Biconditional statement Is a statement that can be written in the form “p if and only if q” This means “if p, then q” and “if q, then p” back
TWISTER hypothesis
The part of a conditional statement following the word if. back
TWISTER quadrilateral
A four-sided polygon back
TWISTER converse
Is the statement formed by exchanging the hypothesis and the conclusion back
TWISTER Deductive reasoning
Deductive reasoning Is the process of using logic to draw conclusions from given facts, definitions, and properties. back
TWISTER hypothesis
The part of a conditional statement following the word if. back
TWISTER definition
Is a statement that describes a mathematical object and can be written as a true biconditional back
TWISTER proof
Is an argument that uses logic, definitions, properties, and previously proven statements to show that a conclusion is true. back
TWISTER triangle
Is defined as a three-sided polygon back
TWISTER counterexample
To show a conjecture is always true, you much prove it. To show a conjecture is false, you have to find only one example in which the conjecture is not true. back
TWISTER Two column proof
Two column proof In this proof you list the steps of the proof in the left column and matching reason for each step in the right. back
