We learned how to use perspective to make 2D shapes look as if they are 3D.   We used 5 different 2D shapes with corners and then drew around them. Then we used ruler skills to draw straight lines from each corner to a dot in the middle of the page.  We pressed down quite hard with a coloured pencil to add a deep colour to the  face of the shape then used lighter pressure to shade the other parts of the shape.
