Active Maths

We had lots of fun during an outdoors investigation this week, learning how to find the approximate age of a tree. We had to measure 1 metre up from the base of the trunk and then use a tape measure to find out the girth of the trunk. As 2.5cm is roughly equivalent to one year of aging, we worked out that we had to divide the girth (in cms) by 2.5 to find out the age of the tree. Did you know that there are lots of trees in our school field older than 100 years?!
