RatioEdge is a standalone HTML app designed specifically for classroom teaching, providing a fast, reliable, and highly engaging way to demonstrate ratio concepts.

Please view the screenshots and video preview before purchase to ensure the app is suitable for your classroom setup and teaching style.

Built for real classroom use, RatioEdge allows you to model concepts visually while also demonstrating formal methods alongside, helping students connect visual understanding with standard written approaches. Its clean, structured design makes abstract ideas clearer and easier to access for a wide range of learners.

You can move seamlessly between teaching and gameplay, using the app both as a clear demonstration tool and as an engaging classroom activity. The 1–2 player mode introduces a competitive element, encouraging participation and making practice more memorable.

Every interaction is immediate and responsive, allowing lessons to flow smoothly and keeping students focused throughout.

RatioEdge is designed to support visual learning, using carefully structured values and interactions so students can focus on understanding relationships rather than getting lost in complex calculations.

As RatioEdge runs as a single HTML file in your browser, you may need to adjust your browser zoom level (+/−) slightly to ensure all controls are fully visible on your screen.

This app is designed for use on desktop or laptop devices and is not intended for use on mobile phones.
