If you follow us over at Smart Apps for Special Needs, you have probably heard of the Tiggly Shapes before. These are fun little shapes that interact with the iPad. Not only does Tiggly create these fun, interactive toys, but they also make FREE apps! We thought it was time to share what everyone is talking about in one handy list. So below, we have all seven FREE apps offered from Tiggly. Preschoolers can practice shapes, colors, numbers and more in these creative apps. (Note, the toys are not required to play, but can add a fun, additional hands-on element).
