KSP Алгебра 8 grade: Формулы сокращённого умножения

This short-term lesson plan for algebra in Grade 8 focuses on the formulas of abbreviated multiplication. It aims to help teachers organize structured lessons and enhance students' understanding of the topic.

The lesson's objective is to develop students' skills in applying formulas of abbreviated multiplication to simplify algebraic expressions. Expected outcomes include recognizing formulas, independently transforming expressions, and applying them to problem-solving. The lesson begins by reviewing polynomial operations to refresh prior knowledge. Then, three core formulas are introduced: square of a sum, square of a difference, and difference of squares. Students engage in transforming expressions like \((a+b)^2 = a^2 + 2ab + b^2\) through guided examples. Teaching methods include explanatory-illustrative approaches combined with problem-based learning in pairs, encouraging discussion of different transformation options. To reinforce learning, students practice identifying which formula applies to given problems from the textbook. The lesson concludes with reflection where students summarize new insights. Assessment at this stage is verbal and formative, focusing on understanding without emphasizing control.
