KSP Алгебра 7 grade: Тождественные преобразования

This short-term lesson plan for 7th grade algebra focuses on the topic of identity transformations. The aim is to develop students' skills in transforming algebraic expressions without changing their value.

The lesson goal is to teach students how to apply identity transformations to simplify expressions and solve equations. By the end, learners will confidently perform addition, subtraction, and multiplication of polynomials and recognize equivalent expressions.
The lesson begins with a real-life problem to motivate simplification of expressions. Next, the teacher explains the new topic using clear examples, such as simplifying (x + 3) + (2x – 5). Students practice transforming expressions like 3x + 2(x – 4) through guided tasks. Group work highlights common mistakes for deeper understanding. The conclusion involves independent exercises on identity transformations and a summary discussion.
Teaching methods include problem-based learning, visual aids, hands-on practice, and pair work to engage students actively.
