Japanese Bonsai artwork

LI: to write a complete blogpost by using a fact about Japan.

I learnt about the Pinus Silvestris,by Stefano Frisoni

It is a Japanese Bonsai art. It is the 4th greatest bonsai artwork.

I searched up on google greatest bonsai trees and Jack and I found a site which had the top ten greatest bonsai trees in the world.

Instead of picking the 1st one we picked the 4th one.

I learnt about Number bounds with the whole class. After Mr Wong told us to make a video in WeVideo.
