• Transum,

• Click on the small green button below the rectangle to see the shaded areas line up in the lower third of the diagram. Was that a revelation? A similar transformation can be applied to the circular pattern. Pupils could be challenged to devise a similar pattern that shows two fifths shaded. It would be wonderful to see what they come up with.

• The problem is that students can get the correct answer with a misconception by counting the number of shaded pieces out of the total number of pieces regardless of their size.

[Transum: Thanks Katie. Maybe we should add that students have to explain how they got their answer. That might help highlight the misconception.]

• Hi, I can't find the green button for the solution to the fractangles problem?

[Transum: Sorry for the inconvenience Steve. The animation was originally written in Flash so it wouldn't work on certain devices and browsers. It has now been rewritten without using Flash so you should be able to see the green button just below and to the right of the rectangle.]

## Hello World

You are buying a (driverless) car. One vehicle is programmed to save as many lives as possible in a collision. Another promises to prioritize the lives of its passengers. Which do you choose?

Welcome to the age of the algorithm, the story of a not-too-distant future where machines rule supreme, making important decisions – in healthcare, transport, finance, security, what we watch, where we go even who we send to prison. So how much should we rely on them? What kind of future do we want?

Hannah Fry takes us on a tour of the good, the bad and the downright ugly of the algorithms that surround us. In Hello World she lifts the lid on their inner workings, demonstrates their power, exposes their limitations, and examines whether they really are an improvement on the humans they are replacing. more...
