Welcome to Issue 56 of the Secondary Magazine.

# Contents

From the editor - Alice in Wonderland
As mad as a hatter, grinning like a Cheshire Cat… Expressions like this are almost part of our language – are you surprised that they were written by a mathematician? Read about Alice in Wonderland’s creator and his links with mathematics.

Up2d8 maths - Double yolk
The fortnightly Up2d8 Maths resources explore a range of mathematical themes in a topical context. Have you ever had a double-yolk egg? On 6 February this year, a woman in Cumbria was surprised to find that she had a box of double-yolk eggs which she only discovered when she cracked them to make her scrambled eggs for breakfast. The media presented this amazing story as beating trillion-to-one odds. But is that really the case? In this resource, students are introduced to the double-yolk story and then invited to question the assumptions made in calculating the probabilities.

The Interview - Bryony Black
Bryony is the Regional Coordinator for Yorkshire and the Humber – another ‘musical’ mathematician. Bryony relates anecdotes focussing on her time in Namibia and Singapore.

Focus on - risk and chance
Public perceptions of chance are often confused with external factors such as skill. Here we build upon the ideas in the Double yolk Up2d8 and investigate other chancy situations.

An idea for the classroom - ski graphs
The age of ‘big brother’ is certainly here! New technology enables ski lift passes to record and display all the journeys undertaken in a day. This resource shows the data from two ski days for interpretation.

5 things to do this fortnight
April birthdays include Wiles (11 April), Euler (15 April) and Gauss (30 April). You may want to use the ‘remind me of this’ tool to remind you about them. Interested? Read on.

Real life issues in the life of a fictional subject leader
In this issue, our subject leader struggles to prioritise his workload and ponders the conflicting pressures of operating on a strategic level versus dealing with the day-to-day.
