Working with... Squares

 Creating an abstract drawing with squares:

1. The teacher will write on the whiteboard 10 numbers in cm., for exemple: 9,3,7,2,1,4,5,2,6. These numbers are the square's side size. 
2. How to draw a square knowing its side.
3. Each student will draw the square wherever he/she wants. 
4. Once all the squares are drawn, the student has to decide wich one is going to be on top or beneath the other. The lines that will not be needed will be erased.
5. Colour the composition.
