Hi Reid,
ReplyDeleteWhat a great activity! Where was the tree stump that you found? Once when I went on holiday in Northland I saw a tree trunk that had started growing in 1100 and was cut down in 1960! How old was that tree? Remind me when we get back to school, and I'll show you a photo.

Hi Reid
ReplyDeleteIt's great to see you are using your learning about concentric circles out and about in the community. There are many different examples of maths shapes in nature. An example of a concentric circle I found was when I cut an onion in half. Can you think of any other examples of concentric circles?
