3-7MR.1.0 Students make decisions about how to approach problems:
3-7MR.1.1 Analyze problems by identifying relationships, distinguishing relevant from irrelevant information, sequencing and prioritizing information, and observing patterns.
3-7MR.1.2 Determine when and how to break a problem into simpler parts.
3-7MR.2.0 Students use strategies, skills, and concepts in finding solutions:
3-7MR.2.1 Use estimation to verify the reasonableness of calculated results.
3-7MR.2.2 Apply strategies and results from simpler problems to more complex problems.
3-7MR.2.3 Use a variety of methods, such as words, numbers, symbols, charts, graphs, tables, diagrams, and models, to explain mathematical reasoning.
3-7MR.2.4 Express the solution clearly and logically by using the appropriate mathematical notation and terms and clear language; support solutions with evidence in both verbal and symbolic work.
3-7MR.2.5 Indicate the relative advantages of exact and approximate solutions to problems and give answers to a specified degree of accuracy.
3-7MR.2.6 Make precise calculations and check the validity of the results from the context of the problem.
3-7MR.3.0 Students move beyond a particular problem by generalizing to other situations:
3-7MR.3.1 Evaluate the reasonableness of the solution in the context of the original situation.
3-7MR.3.2 Note the method of deriving the solution and demonstrate a conceptual understanding of the derivation by solving similar problems.
3-7MR.3.3 Develop generalizations of the results obtained and apply them in other circumstances.
