The follow chart is based on the amount of money that a class of young children deposited in the space of 6 months into their school bank.
Some of the children had a birthday during that 6 month period, and they are represented by the tall peeks.
A few of the children didn’t deposit much money for whatever reason.
The teacher wanted to keep a record because she was curious as to who would be able to save the most in the 6 months.
What she didn't realise, was the difference between the lower savers and the higher savers. That did make her think why.
The children weren’t shown the chart, so as not to cause any issues among them.
So all you need to do is figure out where this all fits into the grand scheme of things.
Sturdy footwear and trousers are best when going for this cache, brambles and nettles will be plentiful in most of the seasons. Care will be needed if going out with children. You'll see why once there.
I'm not putting a checker on the page as it should be an easy puzzle to solve, but will do if people struggle.
