Week May 2-6

Math:

This week students learned about POLYGONS and how they are classified:
'polygone régulier' - 'polygone concave' - 'polygone convexe' - 'polygones congruents'.

On Friday, we worked on finding the PERIMETER of polygons (concept seen in gr.5) but this time we added a few FORMULAS: 

Square:
P = 4c  (c: côté)




Rectangle:
P = 2L + 2l  (L: longueur    l: largeur)

Science:

This week we continued to study 'air' and its characteristics.

A few demo were done in class to demonstrate characteristic #3 :

Air has pressure

We also continued our presentations of 'Actualité scientifique'.
