Bear's maths folder (provided by the school) won't fit in his book bag. The school sell the book bags. I have spoken to my friend eBay and the standard book bag is 37 centimetres long - or roughly half a centimetre too short for the dratted maths folder.
The maths folder is a lot longer than the paper it contains. All the sheets of paper in it are A4 (@ 30 centimetres long). It would probably be inappropriate for me to start grumbling about the free folder that bear has been given.
I spent several pounds on bear's book bag. It is red, his favourite colour, and has his first name on. It is not fancy and it isn't a 'brand' so it should, in theory, have been able to last all through primary school. However I spent most of today failing to find his maths homework today and the easiest way to make sure it has a good chance of going in when it should is getting a bag that fits the folder. Besides, the folder is awkward and fiddly to carry, and I suspect it leaks in the rain. I suppose I could just use a carrier bag. Of course, bear would probably then be the only child using a carrier bag.
Grumble, grumble grumble. Why couldn't they just use a slightly smaller envelope folder? There are some very pleasant ones on eBay for a very reasonable price.
I'm going to see what he's got already in the base of his wardrobe before I commit to anything more.
