1 TWISTERTWISTER

2 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.

3 TWISTER Choose a number.

4 TWISTER conclusion

5 Is the part of a conditional statement following the word then. back

6 TWISTER Paragraph proof

7 Paragraph proof Is a style of proof that presents the steps of the proof and their matching reasons as sentences in a paragraph back

8 TWISTER conjecture

9 Educated guess A statement you believe to be true based on inductive reasoning back

10 TWISTER inverse

11 Is the statement formed by negating the hypothesis and the conclusion back

12 TWISTER negation

13 The negation of a statement p is “not p”, written as ~p back

14 TWISTER Flowchart proof

15 Flowchart proof A second style of a proof which uses boxes and arrows to show structure back

16 TWISTER polygon

17 Polygon Is defined as a closed plane figure formed by three or more line segments back

18 TWISTER Conditional statement

19 Conditional statement Is a statement that can be written in the form of “if p, then q” back

20 TWISTER Inductive reasoning

21 Inductive reasoning Is the process of reasoning that a rule or statement is true because specific cases are true back

22 TWISTER contrapositive

23 Is the statement formed by both exchanging and negating the hypothesis and the conclusion back

24 TWISTER Truth value

25 A conditional statement has a truth value of either true (T) or false (F). False – when hypothesis is T and conclusion is F back

26 TWISTER polygon

27 Is defined as a closed plane figure formed by three or more line segments back

28 TWISTER Biconditional statement

29 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

30 TWISTER hypothesis

31 The part of a conditional statement following the word if. back

32 TWISTER quadrilateral

33 A four-sided polygon back

34 TWISTER converse

35 Is the statement formed by exchanging the hypothesis and the conclusion back

36 TWISTER Deductive reasoning

37 Deductive reasoning Is the process of using logic to draw conclusions from given facts, definitions, and properties. back

38 TWISTER hypothesis

39 The part of a conditional statement following the word if. back

40 TWISTER definition

41 Is a statement that describes a mathematical object and can be written as a true biconditional back

42 TWISTER proof

43 Is an argument that uses logic, definitions, properties, and previously proven statements to show that a conclusion is true. back

44 TWISTER triangle

45 Is defined as a three-sided polygon back

46 TWISTER counterexample

47 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

48 TWISTER Two column proof

49 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

50 TWISTER conclusion

51 The part of a conditional statement following the word then back

52 TWISTER polygonBiconditional statement negation proof contrapositive conjecture Deductive reasoning counterexample conclusion definition Truth value hypothesis converse Inductive reasoning conclusion inverse polygon triangle hypothesis Paragraph proof Conditional statement Two Column proof quadrilateral Flowchart proof
