Review tiers 1–10

Checklists are parent-judged.
Written items: verify against practice set patterns.
Standard text: Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

Practice test scoring
