Unit 3: Reasoning and Explaining (MP2 and MP3)
3.0.2 Connections Across the Standards
The CCSS for mathematics and English language arts (ELA) work together to create coherence across content areas. This is particularly evident when comparing the reasoning and explaining mathematical practices and the ELA College and Career Readiness (CCR) Anchor Standards . Additionally, there are commonalities with the Partnership for 21st Century Skills (P21) that target critical thinking, communication, collaboration, creativity, and innovation.
