Maths investigation

Year 6 spent all morning outside trying to solve a maths puzzle.

They were told they had to plant 10 trees in 5 rows with 4 trees in each row. This resulted in lots of head scratching and puzzled looks.

Everyone then went outside and tried different ways to solve the problem. After about an hour, a bright spark asked whether the rows could cross. 'Yes', they were told! Then, someone else asked whether the rows could be diagonal. Again, 'yes' they were told.... Finally, I offered them a few more nuggets of information such as ' none of the lines are perpendicular'. This seemed to help rather a lot. Here are some photos of the class trying to work out an answer, along with our winning pair, A and R, who were the first to solve the problem.
