8 Mathmatical Practices



Common Core Standards brings to us: The 8 Standards for Mathematical Practice that are being using K-5. These practices place an emphasis on student demonstrations of learning…

1. Make sense of problem solving and persevere in solving them
  • make meaning and look for starting points to its solution
  • analyze what is given and the goal of the problem
  • develop a plan
  • monitor and evaluate progress and change course if necessary
  • check answers to problems and determine if the answers make sense
2. Reason abstractly and quantitatively
  • make sense of quantities and their relationship
  • represent symbolically (equations and expressions)
  • manipulate equations
  • understands and uses different properties and operations
3. Construct viable arguments and critique the reasoning of others
  • understand and use definitions previously taught when justifying results
  • attempts to prove or disprove answers through examples and counter examples
  • communicates and defends their math reasoning using objects, drawings, diagrams, actions, verbal, and written communication
4. Model with mathematics
  • can solve everyday problems
  • can apply assumptions and approximations to simplify complicated tasks
  • use tools such as diagrams, two-way tables, graphs, flowcharts and formulas to simplify tasks
  • analyze relationships mathematically to draw conclusions
  • can interpret results to determine whether they make sense
5. Use appropriate tools strategically
  • can decide which tools will be most helpful (ruler, calculator, protractor)
  • can detect possible errors by using estimation and other math knowledge
  • can make models that enable visualization of the results and compare predictions with data
  • can use technology tools to explore and deepens their understanding of concepts
6. Attend to precision
  • can communicate precisely to others
  • can use clear definitions in discussions with others
  • can state the meaning of symbols consistently and appropriately
  • can calculate accurately and efficiently
7. Look for and make use of structure
  • can look closely to determine a pattern
  • can step back for an overview and shift perspective
  • can see complicated things as being composed of single objects or several small objects
8. Look for and express regularity in repeated reasoning
  • can identify calculations that repeat
  • can look both for general methods and for shortcuts
  • can maintain oversight of the process, while attending to the details
  • can continually evaluate the reasonableness of results.
