Dotty Grids - an Opportunity for Classroom Exploration

Exploration based on the simple environment of a dotty grid can lead students to important mathematical insights about polygons, area, coordinates, and vectors. In this feature, we suggest fruitful starting points to explore with your students, together with advice on how the ideas can be developed in the classroom.
