Painting by Negative Numbers

Far simpler than the negative number maze, this can be used with lower ability students but still has some degree of complexity to some questions.Students should be encouraged to work out all their answers first and then to color using the key (you can check their colors first to make sure they haven't gone wrong). Common mistake - students use the key and apply it to the numbers in the image but these refer to the question numbers. This makes an image of the 4 main South Park characters (upside down to avoid any early guesses).
