CS Unplugged: Image Representation - Colour by Numbers
Use the Colour by Numbers offline activity to explore how a B&W image is made up of pixels, shown as black or white dots which are represented by either a 1 or 0. Using a 0 or 1 to represent a white or black square students create an image on a grid. They supply the coded message for someone else to recreate. Support your teaching and learning with video clips and other related resources.
