This morning bear was playing the maths games again. There was the game where you have some cards face down and you can turn over two at a time and you remove the matches you make. I get that, and I'm often good at it. The twist on this was that you had to match the shape to the equation. So the card showing a circle matched with a = πr² . I remembered that one. I didn't appreciate being faced with the volume of a cone before I had had a caffeine fix. I looked blankly at the screen, looked at an expectant bear and just said, 'Fluffy kittens.' It was all I could manage.
Bear laughed so much he fell off his chair and was still giggling about it as we went to school. I don't envy his teacher dealing with him this morning.
I'm going to have to pull myself together and look the Khan Academy and Open Learn. I need to learn enough so that I can at least have the sense to say, 'not before breakfast!'
On a sidenote, I texted my brother, who is a whizz at maths, to complain. He replied that the volume of a cone was not loud enough. I gave up.
