My world of maths experience

Today my class and I had joined room 6 & 7 we had World Of Maths for the morning in the whare, there were lots of activities to do and we were put into 15 groups, each group had members from a different class, my group had two from room 6 and one from room 7. we did an activity where you have a pile of circles with a hole and a small pole going through it was pretty difficult but we got a bit of help and then it was pretty easy.
