Expanding Double Brackets Lesson

This lesson introduces students to expanding double brackets. The focus is on the area model and the grid method, using online manipulative algebra tiles to go from the former to the latter.

The starter activity walks the students through an introduction to the grid method for multiplication from an area model, an idea that is then revisited in the lesson. The scaffolded worksheet provides student with an opportunity to practise, and includes questions using negative numbers. Open ended extension questions are given which can be displayed on the board.
