This paper examines the pedagogical structure and practical application of the "Lesenka" (Сборник задач и самостоятельных работ / Collection of Tasks and Independent Works) for 9th-grade algebra authored by A.G. Merzlyak, V.B. Polonsky, and M.S. Yakir. It analyzes how the resource facilitates differentiated learning and assesses the utility of associated solution manuals ( reshebniki ). 1. Introduction
Conversely, when used responsibly, a solution manual serves as an indispensable tool for independent study. Advanced pedagogical frameworks suggest using them for: This paper examines the pedagogical structure and practical

The term "ladder" derives from the multi-variant structure of the book. It usually features multiple variants of identical difficulty levels (e.g., Variant 1, Variant 2, Variant 3, and Variant 4). This allows teachers to distribute different variants to adjacent students to prevent copying, or use them for repeated testing and correction of mistakes. 3.
