KSP Алгебра 7 grade: Квадрат разности

This short-term lesson plan for 7th-grade algebra focuses on the topic "Square of a Difference." Students will learn the formula and practice applying it to simplify expressions.

The lesson's goal is to develop students' understanding of the square of a difference formula and their ability to use it in algebraic transformations. Expected outcomes include the ability to write (a - b)² = a² - 2ab + b², demonstrate it with examples, simplify expressions, and solve related problems.
The lesson begins with a brief review of squares and differences, followed by a step-by-step explanation of the formula using examples such as (x - 3)². Students then practice both oral and written tasks, like simplifying (5 - y)² or calculating values for given variables.
Teaching methods include problem-based learning (posing questions about quickly squaring binomials), partial explanation with practice, and group work to encourage idea exchange. Visual aids such as diagrams illustrating the square and its parts help comprehension. The lesson ends with a reflection session where students summarize what they have learned. Assessment is formative and supportive, aimed at encouraging further study rather than control.
