Coordinate Cross is an interactive visual maths app designed to support the teaching and learning of coordinate geometry through modelling, practice, reasoning and games.

The app includes five coordinate grid activities, ranging from four-quadrant Cartesian grids to larger positive-coordinate grids. Pupils drag coordinate tiles to the correct positions, receiving immediate feedback, while teachers can quickly generate new examples.

A dedicated Midpoint activity asks pupils to locate the midpoint between two coordinates, supported by three progressive hints including visual guides and the midpoint calculation.

The Shapes section challenges pupils to complete missing coordinates for squares, rectangles, triangles, rhombi, kites, parallelograms and trapeziums. Optional area display helps connect coordinates with shape properties and geometry.

The Transformation section covers reflections, translations using vectors and function transformations including f(x)+a, f(x)−a, f(x+a), f(x−a), f(2x), f(0.5x), −f(x) and f(−x).

Coordinate Cross also includes:

• Positive and negative correlation generators
• Interactive Line of Best Fit
• 4–7 letter coordinate Anagram activities
• Built-in freehand, straight-line and eraser tools
• A two-player coordinate game including whole-number and half-coordinate targets
• Full-screen classroom display

Suitable for KS2 extension, KS3, GCSE preparation, revision, intervention, tutoring and interactive-whiteboard teaching.
