Around the oak tree

How many hand prints is needed to go around the bench under the oak tree?

We measured the distance around the oak tree with a piece of string.

We then measured the length of the string using a meter ruler. (ans 11 and 1/4 metres)

The number of hand prints that would fit on a meter ruler is 7 and a 1/2.

The number of hand prints that would fit on 2 meter rulers is 15.

Finally our 3 bright mathematicians worked out the answer by using number strategies like counting in ones, counting on, doubling numbers and adding two halves to make a whole.
We found that 82 and 1/2 hand prints is needed to go around the oak tree.
