Indicator 1b

Indicator 1b asks whether the majority of class time is spent on the grade's major clusters. The retrieved evidence shows full-length 60-minute daily lessons in Module 5 devoted entirely to fractions (3.NF.1, 3.NF.3c, 3.G.2) — major work of Grade 3 — across multiple multi-day topics ([E1], [E4], [E5], [E6], [E8], [E9], [E11]), with fluency time additionally reinforcing the 3.OA major cluster ([E4], [E10]). Even the end-of-year review module devotes its work to consolidating major Grade 3 skills including fractions, multiplication, and division ([E2], [E7]). This structural design — substantial instructional days allocated to major-cluster standards with full-period lessons — supports the indicator. Confidence is moderate because only Grade 3 Modules 5 and 7 were retrieved rather than the full scope-and-sequence needed to confirm grade-wide time allocation.
