## ‘In it to win it’… Don’t miss the chance to win Olympic tickets!

The ** Out of the Blocks** Maths and Science Series for London 2012 is proving very popular in schools. So if you’re still looking for a STEM Club activity with the prospect of you and your team winning Olympic event tickets, there are still 2 weeks left to enter a team in the Maths and Science Challenge 2012 –

**closing date for entering a team is 15 May 2012!**

The Challenge is for teams of 4 to 6 students to plan a major sporting event in your local area, using their maths and/or science skills to create a great presentation for STEM Challenge local-area judging between 21 and 30 May.

**So effectively you have until almost the end of May to come up with a winning project! **

## Rugby World Cup Maths: FREE Activity to download

The **Rugby World Cup** is upon us. There’s a lot more mathematics to rugby than you might think, and we’ve created a bespoke *Beast Index* to prove it.

Keep your class on their toes with these **AO1** and **AO3 problem-solving questions** on averages & range, and using formulae:

## Evariste Galois: the 20 year old mathematician who fought a duel

Some stories you just couldn’t make up. **Evariste Galois** was a young French Mathematician, who wrote his most important work on algebra and symmetry, now known as **Galois theory**, the night before dying in the strange symmetry of a pistol duel. And that’s without mentioning Galois’ involvement in the **1830 Revolution**, his imprisonment, and his unrequited love affair.

Our thanks to **Republic of Mathematics**, which brought these two videos to our attention. The first is a TED talk by Marcus du Sautoy on Galois and symmetry, the second is a short documentary on Galois’ life.

Sometimes it’s hard to engage students with the lives of great mathematicians. Have a go with this one. The ingredients are remarkable.

## SHERLOCK HOLMES MATHS COMPETITION – Episode 3 Solution…

Our congratulations to the **Episode 3** winners of our **Sherlock Holmes Maths Competition:**

**VIKY LAWSON & EMMA BRIGHTWELL FROM GLOUCESTERSHIRE COLLEGE…**

…for successfully working out where Holmes and Watson must go next.

**AND THE ANSWER IS:**

**…BOROUGH MARKET!**

We’ll be sending the winners a free **Sherlock Holmes DVD** (the 2009 Guy Ritchie version) and a **tin of Cadbury’s heroes.**

**OUT OF THE PAN AND INTO THE FIRE:**

**Discover what happens on Wednesday when Holmes and Watson arrive at Borough Market in Episode 4 to face a BONFIRE NIGHT challenge.**

Here is the winning solution to Episode 3:

4 diamonds = 1684. To work out 1 diamond, 1684 / 4 = 421

Code 2403 is 3 diamonds and 2 circles. 3 diamonds = 421 x 3 = 1263

2403 – 1263 = 1140.

1140 = 2 circles. To work out 1 circle, 1140 / 2 = 570.

Code for hatch is 1 diamond and 3 circles = 421 + (570 x 3) = 2131

Therefore code for hatch is 2131.

To work out the route of the thief, the probability has been worked out for each potential route:

Fractions have been turned into decimals to make it easier:

Angel Islington – University College: 0.5 x 0.25 = 0.125

Angel Islington – British Museum = 0.5 x 0.05 = 0.025

Angel Islington – House of Lords = 0.5 x 0.7 x 0.07 = 0.024

Angel Islington – Imperial War Museum = 0.5 x 0.7 x 0.5 = 0.175

Angel Islington – Smithfield Meat Market = 0.1

Angel Islington – St Pauls Cathedral = 0.4 x 0.25 = 0.1

Angel Islington – Bank of England = 0.4 x 0.75 x 0.125 = 0.0375

Angel Islington – Borough Market = 0.4 x 0.75 x 0.625 = 0.1875

Angel Islington – Tower of London = 0.4 x 0.75 x 0.25 = 0.075

From this, the route with the most likely outcome is Angel Islington to Borough Market.

So the thief is at Borough Market.

## Quick reminder…

**Episode 1: “Smash ‘n’ Grab”**

Solve the mathematical clues in this detective story with your students, and help Holmes and Watson to track down the thief of the World’s largest ruby!

This Autumn term, we’re running a **fortnightly competition** to give AQA GCSE Maths classes some FREE practice of **AO2 and AO3** questions. Each Episode is presented as a two-page entry from Holmes’ own case notes:

And here’s the accompanying worksheet:

**How the Competition Works:**

1. Download the full Episode, and the Worksheet, by clicking on the 2 images above. Print these out for your classroom, or project onto your whiteboard. They contains the narrative of the story with Maths challenges, testing AO3 problem-solving skills. You may find it helpful to use the map of London, which we published **in an earlier post**.

2. The solution to the Maths challenges is** the next location Holmes and Watson must go to.** Submit your solutions, *together with an explanation*, either by leaving a comment on this post or by sending an email to **SherlockH_221B@yahoo.co.uk** Deadline: **5pm on Tuesday 28th September, 2010.**

3. You can send the solution on your own behalf, or on behalf of your GCSE Maths class. If the latter, please specify the name of the class. If you have more than one class, you can make more than one entry.

4. The winning solution will be chosen at random from all correct solutions, and published next Wednesday, 29th September. We will send this prize to the winner: **a DVD of the 2010 BBC Sherlock Holmes series and a tin of Cadbury’s Heroes!**

5. There will be six episodes in total – teachers can join this competition at any stage. There’s no need to register and you can send solutions for as many, or as few, of the Episodes as you want. You can keep up-to-date with every Episode on **this dedicated page of our blog**.
