Expanding Double Brackets with Surds - Using the Grid Method WORKSHEET DESCRIPTION
This worksheet introduces students to expanding double brackets involving surds using the grid (area) method.
It begins with scaffolded examples where grids are partially completed, guiding students step-by-step through the multiplication process. This structured approach is perfect for learners encountering surds and expanding brackets for the first time, as it helps them visualise how each term is distributed.
As the worksheet progresses, the level of support gradually decreases, encouraging students to apply the grid method independently. Later questions involve more complex expressions and require simplification of surd terms, reinforcing key skills.
The progression ensures that students move from supported practice to confident application, making it a valuable resource for building fluency in expanding surds.
