Area, 2D Shapes, Patterns and Sequences
Key Stage: 3 ★
Can you find a relationship between the area of shapes on dotty grids, and the number of points on their perimeter and in their interior?
At its simplest level this problem allows students to consolidate their understanding of how to calculate the area of irregular shapes. The extra mathematical demand comes from requiring students to identify the relationship between three variables.
This resource has comprehensive teachers' notes and resources, linked from the problem page. This includes possible approaches and key questions, as well as possible support and extensions.
