Sherlock Holmes Episode 1 solution…

September 29, 2010 Leave a comment

Our thanks to everyone who’s taken part in Episode 1 of our Sherlock Holmes competition: The Mystery of the Devil’s Eye!

In Episode 1, Holmes and Watson are called to Harrods by a frantic Inspector Lestrade: the world’s largest Ruby, the Devil’s Eye, has been stolen and he doesn’t know where to go next.  There are just a few cryptic clues that only a master of deduction, and mathematics, could solve…

AND THE ANSWER IS…

THE LONDON EYE! 

Our congratulations to this week’s winners: CLASS 10 Set 3 from Sutton Grammar School in Surrey.

Here’s their answer:

If you work out the volume of the ruby; (area of rectangle + area of trapezium) x length

((10 x 3.5) + (7 x 2.5)) x 11 = 577.5 cubic cm.

The Mass is density x volume;     so 4 x 577.5 = 2310 g

If we split the answer 2310 in to 2 parts we got the co-ordinate (23, 10)

This is THE LONDON EYE

{and the thief keeps talking about eyes at the start of the note}

[We also worked out the thief got through Door B;   if you draw the lasers as lines on the graph, all the doors are blocked except B]

We’ll be sending the winners a Sherlock Holmes DVD and a tin of Cadbury’s Heroes in the post! 

DON’T MISS OUT ON WHAT HAPPENS WHEN HOLMES AND WATSON ARRIVE AT THE LONDON EYE IN EPSIODE 2:

NEXT WEDNESDAY, 6TH OCTOBER

And remember, you can join this competition at any time.  There will be six Episodes in total, with a prize to the winner of each one.  You can keep up-to-date with all details of the competition on this page of our blog.

Back in the depths of August, we published the teacher resources for our AQA Functional Maths 2010 series: a Teacher Guide and an ActiveTeach DVD-Rom.  Both resources cover Levels 1 & 2.  They fit hand-in-glove with our Functional Student Book, with which a lot of our readers are already familiar.

The Teacher Guide and ActiveTeach are, of course, awesome.  But don’t take our word for it, here are some samples:

AQA Functional Maths ActiveTeach: presents the Student Book on-screen with access to video clips, audio files and interactive content. Click to access FREE online demo.

Quick note on the Teacher Guide contents: its chapters are matched to the Student Book, and it offers lesson plans, teacher notes, extension material for brighter students, and guided practice for weaker students. The Guide also contains Level 1 and Level 2 practice exam papers, written bespoke for the new 2010 spec.
