The materials clearly contain both required components. Adult-level explanations of complex grade-level concepts appear through unit/lesson/activity narratives and curated essays addressing challenging topics like fraction division (with justification for invert-and-multiply), order of operations, and equivalent fractions [E2][E3][E6][E9][E12]. Adult-level explanations of concepts beyond the current course are explicitly curated—IM states articles show 'where concepts lead beyond the indicated grade level' [E1], including the number line K-12, trigonometry as an example of angle concepts beyond elementary, and the Number System 6-8 progression for K-5 teachers [E7][E12]. This structural design (named scholarly articles by McCallum, Lahme et al., plus Progressions mappings) intentionally supports teacher content knowledge of both grade-level and beyond-grade-level mathematics [E11].
