Standards for Mathematical Practice
The eight standards for mathematical practice describe the “know-how” or habits of mind that we seek to develop in students. These practices define important methods and skills that students need to be mathematically proficient.
-
-
1. Make sense of problems and persevere in solving them.
Students are able to “stick with” problems and will try multiple methods to reach a solution.
-
2. Reason abstractly and quantitatively.
Students understand that written numerals represent real world objects and quantities.
-
3. Construct viable arguments and critique the reasoning of others.
Students are able to explain their own mathematical ideas and strategies and they respond to the thinking of others.
-
4. Model with mathematics.
Students use pictures, objects, numbers, and/or words to express their mathematical thinking and reasoning.
-
5. Use appropriate tools strategically.
Students select the appropriate tools and resources to solve a problem.
-
6. Attend to precision.
Students use detailed and accurate mathematical vocabulary to communicate mathematical understandings.
-
7. Look for and make use of structures.
Students notice attributes and structures in mathematics such as: sorts shapes by the number of sides or recognizes that 4+6=10 and 6+4=10.
-
8. Look for and express regularity in repeated reasoning.
Students identify patterns, make predictions and use repetitive actions that support computation: 12 + 5 is the same as 10 + 2 + 5.
