Note:
The benchmarks for mathematical processes articulate what students should
demonstrate in problem solving, representation, communication, reasoning
and connections at key points in their mathematics program. Specific
grade-level indicators have not been included for the mathematical
processes standard because content and processes should be interconnected
at the indicator level. Therefore, mathematical processes have been
embedded within the grade-level indicators for the five content standards.
