Yenka Technology is a powerful, but easy-to-use, simulator for systems and control. It lets you design circuits, with a vast library of digital and analog electronics, and convert them to PCBs for manufacture. You can program PIC or PICAXE chips, and model the circuit in full 3D, with mechanical inputs and outputs.

Yenka Mathematics lets you experiment easily with 3D mathematical models, to learn about statistics, probability, geometry and coordinates. It can be used as a flexible demonstration tool - for example, on a whiteboard. Alternatively, students can use Yenka themselves, to learn by experimenting in Yenka's 3D world.

Yenka Programming is a new, exciting way to introduce computer programming. It lets you use simple flowcharts to control either human characters or on-screen animations. It's a novel way to teach about control, starting with the basic concept of a sequence of steps, and moving on to loops, variables and functions.

Yenka Science is a highly interactive virtual lab, which lets you model physics and chemistry experiments safely and easily. It brings together the features of Yenka Physics and Yenka Chemistry. Simulate experiments however you wish: design circuits and optical systems, model reactions using over 100 different chemicals, investigate wave propogation or accelerate masses. Poweful graph tools let you follow your experiments' progress.

Our Sumdog maths games website is designed to help you practice your mathematics - in an enjoyable way. All of Sumdog's games are free to use at home or in school. Each one covers 100 numeracy topics across 10 levels, and most are multiplayer - letting you play with other students around the world.
