• Hello, this was easy peasy but we enjoyed it, particularly Tamera who says she has a room at home shaped like that.
We love a good starter, especially on a Monday morning. x
• Lewis Paton, Carnoustie High School.
•
• It was shapetastic.
• 7abM3 Maths Class, King Alfred's College OXON
•
• Today's starter sparked off a good chat about shapes. Eventually most of my class could see how to get the answer.
• Transum,
•
• So when the answer is realised there is typically a sense of amazement that the calculation is so simple. As a follow-on activity pupils might be challenged to draw another seemingly complex shape that has a simple calculation to calculate the perimeter. This is a useful activity which helps provide a sound background for geometrical problem solving in general.
• Winnie, London
•
• My year 6 class just loved this puzzle.
• Mrs Walker, St.James' School
•
• My class had a discussion about this perimeter puzzle and I was then able to teach my class using this problem. A great morning starter.
• My Class, Lord Grey School
•
• AWESOME!! It took us a while but we got it in the end.
• Mr Lloyd, DSLV 5TL
•
• Some of the class got this straight away, but the rest of the class couldn't see the answer.
• British International School, Moscow
•
• My class found this problem angleastic!!!!!
• Lloyd Entwistle, Salford City College
•
• Loved this problem. Students first complained that they did not have enough information but then slowly realised that they could solve it!

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...

 Teacher, do your students have access to computers?Do they have iPads or Laptops in Lessons? Whether your students each have a TabletPC, a Surface or a Mac, this activity lends itself to eLearning (Engaged Learning).
