Edge detection (Quick Draw)
Unplugged Shape Detection
Our first activity has students exploring the concept of how a computer can use lines to represent a shape, perhaps a car or an animal. As a whole class, the teacher works with students to look at an image and to talk about the various shapes they see – triangles, circles, rectangles. In the first activity, students copy the first image of the elephant by drawing the shapes over the top of the kangaroo. Students can also take the shapes from this worksheet and work on a number of images, trying to fit the shapes to the image, and seeing whether there are common shapes that occur for the same type of image, for example always having circles to represent wheels on a car.
Happy draw game
