Semester 3A · Grade 3 mathematics
Seven complete instructional chapters and original cumulative practice assessments.
Seven independently authored instructional chapters follow the public Dimensions Math 3A topic sequence. Chapters and semester assessments have passed internal editorial review. External educator review and learner field trials are still pending. This material is intended for learning and low-stakes practice, not official placement decisions.
Work through the lessons and chapter practice, then use the cumulative review and untimed semester practice examination to identify skills to revisit. Solutions are openly available; these are not secure school placement tests.
