Presto Bingo Shapes is SPUR's shape-finding app for kids featuring the illustrations of Joyce Hesselberth. Available for the iPhone and iPad, here on the App Store.
PrestoBingo Shapes provides an introduction to geometry for children. Circles, diamonds, ovals, rectangles, semicircles, squares, triangles, trapezoids, and triangles are explained and identified. Each screen presents a different shape-finding puzzle and kids are verbally and visually prompted to click on the shapes. Animations throughout the app explain geometric forms concisely, and encourage children to see shapes in a unique way. When prompted for more information, shapes are described in terms that young kids can understand, "A trapezoid is a triangle with the top cut off. It can be a tent in the woods, or a lampshade, or a ship sailing away."
