Expanding Brackets — Interactive Lesson (Year 8)

Do your students forget to multiply every term? This 37-slide interactive lesson teaches expanding brackets from single brackets to the box method.

Mastering Expanding Brackets in Year 8 Maths

Students learn to expand simple algebraic expressions, expand and simplify expressions with two or more brackets, and expand using the box method. They start with single brackets such as 4(2x − 3) = 8x − 12 and x(x + 5) = x² + 5x, including negative multipliers, then simplify expressions such as 3(x − 4) − 2(x + 5). Double brackets follow, with the box method used for (y + 3)(y + 5) = y² + 8y + 15, and area and volume problems apply the skills.
