: The GDZ is intended as a tool for self-checking rather than just copying. It helps students identify specific gaps in their logic before formal classroom testing.
The primary feature of the (specifically for grades 7–11) is its structure, which mirrors the textbook's multi-level differentiation . These solutions are designed to support a curriculum where tasks are categorized by difficulty to accommodate different learning speeds. Core Features of Ershova's Geometry GDZ : The GDZ is intended as a tool
: Focuses on basic constructions, the Theorem of Thales, and properties of triangles and parallel lines. the Theorem of Thales
: Transitions into stereometry (3D geometry) and complex calculations involving volume and spatial figures. : The GDZ is intended as a tool
