Expanding & Factorising with Area

Grid-based area model where (x+3)(x+2) becomes a rectangle divided into labelled sub-areas.

Why this tool helps: Expanding and factorising feel like arbitrary symbol manipulation until students see the geometric area model.

Year levels: Year 8, Year 9, Year 10 Curriculum: Australian Curriculum aligned
