Outcome: F20.2 Demonstrate understanding of inductive and deductive reasoning including: • analyzing conjectures • analyzing spatial puzzles and games • providing conjectures • solving problems. Indicators: Note: It is intended that: • proofs NOT be limited to the two column proof style • analysis and conjectures related to spatial puzzles and games be incorporated throughout the course. a) b) c) d) e) Make conjectures by observing patterns and identifying properties, and justify the reasoning. Provide examples of how inductive reasoning might lead to false conclusions. Critique the following statement "Decisions can be made and actions taken based upon inductive reasoning". Identify situations relevant to self, family, or community involving inductive and/or deductive reasoning. Prove algebraic number relationships, such as divisibility rules, number properties, mental mathematics strategies, or algebraic number tricks using deductive reasoning. f) Prove conjectures using deductive reasoning. g) Analyze an argument for its validity. h) Identify errors in proofs that lead to incorrect conclusions (e.g., a proof that ends with 2 = 1). i) Solve situational questions that involve inductive or deductive reasoning. j) Determine, explain, and verify strategies for solving puzzles or winning games, such as: • guess and check • analyze a pattern • make a systematic list • create a drawing or model • eliminate possibilities • solve simpler problems • work backward. k) Create a variation of a puzzle or a game, and describe a strategy for solving the puzzle or winning the game. Level Scale Pre-Requisite Knowledge 1 B - Beginning There is a partial understanding of some of the simpler details and processes. Prior knowledge is understood. 2 A – Approaching No major errors or omissions regarding the simpler details or processes, but assistance may be required with the complex processes. Descriptor Indicators Students who are not able to be independently successful with level 1 questions will be given an E. Recognise and describe patterns. Knowledge and Comprehension Students who are successful with level 1 questions or those who are successful with level 1 or 2 questions with assistance will be given a B. Applying and Analysing Students who are able to be successful with level 1 and level 2 questions, or those who are successful with higher-level questions with assistance, will be given an A. Number and geometry facts. M – Meeting No major errors or omissions regarding any of the information and/or Evaluating and Creating Students who are independently successful with Identify situations relevant to self, family, or community involving inductive and/or deductive reasoning. I understand the meaning of and difference between Inductive and Deductive reasoning. I can identify examples of inductive and deductive reasoning both inside and outside school. 3 Student-Friendly Language Make conjectures by observing patterns and identifying properties, and justify the reasoning. Provide examples of how inductive reasoning might lead to false conclusions. Critique the following statement "Decisions can be made and actions taken based upon inductive reasoning". Prove algebraic number relationships, such as divisibility rules, number properties, mental mathematics strategies, or algebraic number tricks using deductive reasoning. Prove conjectures using deductive reasoning. Analyze an argument for its validity. Identify errors in proofs that lead to incorrect conclusions (e.g., a proof Inductive Reasoning: I can identify and explain patterns. I can make conjectures based on those patterns. I can find examples where patterns do not continue which shows that inductive reasoning can lead to false conclusions. I can critique statements like statement "Decisions can be made and actions taken based upon inductive reasoning" Deductive Reasoning: I can use deductive reasoning to prove algebraic number relationships, such as divisibility rules, number properties, mental mathematics strategies, or algebraic number tricks I can use deductive reasoning to prove conjectures. I can analyze the statements of an argument to see if they are based on correct reasoning. processes that were explicitly taught. This is the target level for proficiency. level 3 or level 4 questions are given an M. 4 In addition to level 3 performance, indepth inferences and applications go beyond what was explicitly taught. Students successful at level 4 will receive supplementary comments specific to their achievement in addition to the M. that ends with 2 = 1). Solve situational questions that involve inductive or deductive reasoning. Determine, explain, and verify strategies for solving puzzles or winning games, such as: • guess and check • analyze a pattern • make a systematic list • create a drawing or model • eliminate possibilities • solve simpler problems • work backward. Create a variation of a puzzle or a game, and describe a strategy for solving the puzzle or winning the game. I can identify mistakes in proofs that lead to incorrect conclusions (like 2 = 1). I can solve problems involving inductive or deductive reasoning. I can use reasoning strategies to solve and explain the solutions to puzzles and games. • guess and check • analyze a pattern • make a systematic list • create a drawing or model • eliminate possibilities • solve simpler problems • work backward I can create my own puzzles and games and describe the strategies needed to solve or win them. I can search challenging puzzles to solve using inductive and deductive reasoning strategies. I can design and produce a challenging game.
