Methods for solving two-variable linear systems, including substitution and elimination.

For students, these exercises provide a clear benchmark. Solving a "Shestakov variant" is often considered a rite of passage for 13-to-14-year-olds preparing for higher-level mathematics. Resources like Vedantu's NCERT guides and Open Up Resources offer similar structured approaches for international curriculums, emphasizing the importance of and geometric reasoning at this age.

Deepening the study of linear functions and introducing the properties of quadratic functions.

The "Shestakov method" is praised for its . Most independent works are divided into multiple variants (варианты), allowing teachers to give different versions of the same test to students sitting next to each other, ensuring academic integrity.

Today, many of these classic independent works are available through digital educational platforms. Sites like Scribd and various Russian educational portals host digitized versions and "GDZ" (готовые домашние задания—ready-made homework solutions) to help students check their work.
