In Ershova's 7th-grade manual, the year is split into two main "stories": 1. The Algebra Story: Expressions and Equations The goal here is to move from simple numbers to variables ( The Geometry Story: Lines and Triangles : Learning

: For geometry specifically, YouTube tutorials can show you how to set up equations from geometric diagrams, which is a major part of the 7th-grade curriculum. The "Story" of 7th Grade Math (Key Concepts)
