The materials explicitly attend to balancing the three aspects of rigor, with a dedicated 'Balancing Rigor' framing [E1] and an account of activities designed variously for developing a concept, mastering a procedural skill, or applying mathematics to real-world problems—showing all three present independently [E3][E4][E5][E11]. They also engage multiple aspects simultaneously: the materials state the three aspects are 'interwoven'/'interconnected,' with procedural fluency supported by understanding and application requiring both understanding and skill [E3][E6], and anchor contexts used to motivate concepts [E11]. This structural evidence supports both required components (independent presence AND simultaneous engagement) throughout each grade level.
