Here's yet another free Windows 8 education app from nsquared. Like their other apps (missing card, numbers, and snap), it's ideal for pre-school and primary school children, and is designed to support collaborative learning – allowing groups of students to work together on a single Windows 8 touch-enabled PC or tablet.
nsquared letters is a free form application designed for children to use with or without guidance. It allows students to explore words in virtually any language that uses the Latin alphabet. And because it uses the multi-touch features of Windows 8 devices, it allows for many children to use it at the same time. So you could put a tablet flat on a desk, and have a group of four children around it all using it at the same time. The app is free, and there are different activity packs available as an in-app purchase.
