Two-dimensional drawings like pictures or lines belong to the semi-concrete level, which sits between using real objects and using pure numbers or symbols. This pictorial stage lets learners represent quantities with visuals—pictures or diagrams—so they can see and reason about a problem before moving to abstract symbols. It helps build a bridge from concrete manipulation to abstract thinking by letting learners visualize the concept without needing physical items. Using real objects would be the concrete level, and using only digits or symbols would be the abstract level, while Mastery isn’t a standard stage in this representation progression.
