Problem Solving |
| A problem solving heuristic is a series of generalized steps that is helpful to think about when solving problems.
|
Begins and follows through solving problems with a heuristic.
- Identify a problem in different contexts.
- Use a heuristic (generalized pattern/strategy) to solve problems.
- Use metagcognition during the process.
- Identify the words in a problem that describe the mathematical relationships and operations.
- Accurately explain a problem in their own words.
- Identify information needed to solve the problem.
- Identify unneeded information in a problem.
Select a strategy to solve the problem.
- Try a different strategy when one appears to be at an impass.
- Solve the problem.
- Try to solve the problem in a different manner to gain confidence in your answer.
- Reflect on what was learned and how it might be used in other contexts. the process and the accuracy of the solution.
- Share the process, strategies used (successful and unsuccessful), attitudes, and solutions.
|
Develop a generalized pattern/strategy (heuristic) to solve problems. |
Use a heuristic when confronted with new mathematical situations that related to their lives. |
Problems can be solved with different strategies.
Strategies for solving problems are:
- Work a simpler problem
- Trial and error, guess and check
- Work backwards
- Use smaller numbers
- Systematic steps
- Look for patterns
- Physically acting - out the problem
- Use a graphical representation - model, drawing picture or diagram
- Problems can be solved with models. Organize data to look for patterns sequence, chart, table, making a graph,
- Venn diagrams
- Process of elimination or process of identification
- Write an open sentence
- Use algebraic reasoning
|
- Apply and adapt a variety of appropriate strategies to solve problems;
- Use manipulatives to represent objects and actions in the problem.
- Act out the problem.
- Use models as a strategy to think.
- Draw pictures as a strategy to think through a problem.
- Break a problem into two related problems and solve the original problem in two steps: one for each problem.
- Use trial and error, guess and check.
- Recognize and describe patterns.
- Categorize information to find relationships and patterns that will assist reasoning and proof.

How many pockets are there on the indoor clothes of the students |
- Do students come up with their own strategies for solving problems, or do they expect others to tell them what to do?
- What do their strategies reveal about their mathematical understanding?
- Do students understand that there are different strategies for solving problems?
- Do they articulate their strategies and try to understand other students' strategies?
- How do students use materials to model a mathematical situation to find solutions?
- How do students keep track of and record their work? Is it difficult for them to talk, draw, and write about their work?
- Do they solve mathematical problems in ways that make sense to them?
- How do they work with peers cooperatively, participate in whole class discussion and share ideas, materials, creations? Learn form the thinking of others
- How do they work independently? Rely on their own thinking
- When given choices what do they choose? The same, different, stay in one place, move comfortably, move around a lot...
|
- Reflection is
- Metacognition helps to solve problems.
|
- Monitor and reflect on the process of mathematical problem solving
- Use self talk, group discussion, to talk through a problem and problem solving process to reflect on all the decisions that are possible to better insure an accurate solution.
|
|
|
| The more problems I solve (persistence) the easier it is to solve problems and use mathematics.
Following a heuristic is helpful to think about what you know or have done and what you need to find out or do. |
Build new mathematical knowledge through problem solving; |
Using provided story problems, students will high light the necessary information and cross out extraneous information. |
|

Reasoning and Proof |
Reasoning and Proof |
- Every idea in mathematics has to be proved (skeptical) before it can be used as a mathematical idea.
- For a proof to be valid every change or every step has to have a reason that justifies its accuracy.
|
Recognize reasoning and proof as fundamental aspects of mathematics;
- Use data to support a mathematics idea.
- Asks others to explain their reasoning
- Desires to explain their understanding, reasoning, and procedures.
- Rejects solutions that have insufficient evidence and lack reasonable explanations.
|
|
|
- A conjecture is a conclusions based on insufficient evidence.
- Conjectures are ideas used to reason on evidence (which provides no doubt) to a conclusion.
|
- Make and investigate mathematical conjectures;
- Makes generalized statements from specific examples.
|
|
|
| A mathematical arguement that is used to prove a conjecture must have a valid reason for every change (or every step) from what is in question to something that is know or has previously been proven mathematically. |
Develop and evaluate mathematical arguments and proofs;
- Explains how a problem was solved.
- Interpretes and explains other students' solutions as accurate, inaccurate, or not sure.
- Looks for addition examples for justification.
- Sove problems in different ways to justify accuracy.
- Recognize that a proof has to justify every possible example.
- Uses concrete representations to justify all examples of an argument and proof.
|
|
|
- Mathematical ideas can be proven by manipulating a representation of the conjecture.
- Mathematical ideas can be proven by manipulation of symbols based on previously proved manipulations.
|
Select and use various types of reasoning and methods of proof from the following:
- Uses concrete representations to justify all examples of an argument and proof.
- Uses models to demonstrate and justify reasoning.
- Use symbols to represent all possibilities when proving a conjecture.

Communication |
- Mathematical ideas can be communicated.
- Written and spoken words, pictures, manipulatives, symbols, and movements help communication.
- Charts and graphs can be used to see relationships.
- Different ways to communicate mathematically iclude speaking, writing and drawing, use manipulative objects, acting it out, pictures, and symbols.
|
Organize and consolidate their mathematical thinking through communication;
- Seeks new vocabulary, because of the power it provides by representing a grouping of specific ideas.
- Speaks, manipulates, draws, and writes to collect, organize, chart, and interpret mathematical ideas.
|
|
|
- Mathematical ideas can be communicated more accurately by matching the kind of communication to the intended audience.
- Mathematical ideas can be communicated in virtually every medium known.
- Mathematics is most often communicated orally, in writing, and through graphic representations.
- The closer the communcation is to accurately describing the mathematical ideas, the more likely the communication will be understood.
|
- Communicate their mathematical thinking coherently and clearly to peers, teachers, and others;
- Writes, draws, uses manipulatives, and animates objects to represent externally their internal understanding.
|
|
Acts out problems when solving.
Develops methods for recording numerical information: pictures, words, and/or numbers |
| People think in different ways so it is important to be open minded to understand what other people mean mathematically. |
- Analyze and evaluate the mathematical thinking and strategies of others;
- Uses other peoples oral and written ideas.
|
|
|
| I can use mathematical language or ideas to communicate better my ideas to other people.
When other people use mathematical ideas that I understand, it helps me understand what they mean better. |
- Use the language of mathematics to express mathematical ideas precisely
- Uses mathematical concepts, representations, vocabulary, and, symbols to explain parts of data, whole sets of data, mathematical processes, proceudures, examples, and solutions orally, in writing, pictures, using models, symbols, and acting/demonstrating real world problems.
