I have received another Email from the classroom with 3 pictures in it

I am curious about:
1) the third picture
the pieces have been softly folded and I would like to ask about the significance of this?
2) the middle picture
the fragments on the yellow ground again some of the mark making has a folded/furled look, others are more rhythmic, are these an exploration of randomness?
3) in picture no. 1
I see girls at work and both elements on the table, so this tells me they are related in some way, I would like to ask the children how they are related?

Looking forward to your answers…. :)
