It would be very useful to reinforce some of the concepts learned in the workshop, as some children may still be struggling with them. First discuss each of the concepts below and see if children can define them. Then:

Proportion: Draw an object (which the children can see - a real one or a photo) out of proportion - for example, a cup which is too wide or too tall, or simply the wrong shape. Get a child to come up to the board and correct it - not by erasing lines but by drawing better lines over the top. Erasing doesn't generally help - the incorrect lines are useful as a guide to drawing better ones.

Symmetry: Draw an object which is supposed to be symmetrical, without the correct symmetry. Get a child to correct it (as with proportion).

Ellipses: Go over how to construct an ellipse - draw two lines of symmetry crossing, then construct the curves so the overall shape is symmetrical. Now draw incorrect ellipses and get children to correct them. You can draw correct ellipses using the draw function in Word.

                      Ellipses with lines of symmetry

Cylinders: Go over how to construct a cylinder-type object, such as a cup or vase. Let children practise drawing from a real cylindrical object (if you can find enough to go around). They can also try drawing cylinders on their side - in which case the longer line of symmetry is vertical and the shorter is horizontal:

2. Try More Complex Objects

Many objects can be reduced to underlying basic shapes such as spheres, cones, cubes and cylinders. Show the children how an object such as a bottle is made of two cylinders joined by a cone shape. If the children can construct these first it will make their final drawing more accurate. It is generally best to get the underlying shapes right first - checking and adjusting - then do shading and details later.

3. Art Critique

Children can examine each other's drawings and give comments on how they could be improved with respect to line and shape (but also shading and colour). Then the child can improve his or her own work based on these comments.
