Symmetrical bugs

We love MATHS ART in Room 4.  This week we took notice that insects, bugs and butterflies in nature are often symmetrical.  So we created our own symmetrical bug art work.
We began by folding our page in half vertically and drawing half of our unique bugs with chalk, then going over the chalk lines with black pastel.  But how did we make sure that we made it completely symmetrical?  We folded our bugs back in half again and pressed down hard so that the pastel transferred to the other side.  All we had to do then was to go over the pastel lines.  We coloured our bug in symmetrically and finally dyed the background.  The final products are very eye-catching!
