    • Teacher's Instruction
    1. Teachers should teach simple mathematical sums - sides and angles of shapes before giving this exercise.
    2. Use the exercise to reinforce children’s understanding of basic shapes. Relationship between the length of various sides in various shapes. Challenge the students to draw a Rhombus or Parallelogram. Challenge them to draw a triangle other than an equilateral triangle. If the children know Pythagoras theorem, you can have them draw a right angle triangle and figure out what the hypotenuse will need to be. This will help them understand the shapes better.
    3. Points to Ponder: Observe that to draw a regular polygon with N sides, you will need to turn 360/N degrees. Why? The sum of the interior angles of a N sided polygon will always be (N-1) * 360 starting with triangles and quadrilaterals. You can help students understand that.
