Primary Magazine Issue 24A proof from Euclid's elements that, given a line segment, an equilateral triangle exists that includes the segment as one of its sides. The proof is by construction: an equilateral triangle ΑΒΓ is made by drawing circles Δ and Ε centered on the points Α and Β, and taking one intersection of the circles as the third vertex of the triangle

Editor's extras
Interventions, transitions and standards – details of all are in this issue of the magazine with personal reflections and national news updates.
 
It's in the News!
In Issue 22 we looked at earthquakes following those in Haiti and Chile, and we revisit that geographical, scientific and mathematical theme again as we consider the volcano that brought silence to our skies! The slides provide opportunities for work with such mathematical concepts as measurement, coordinates and ratio.
 
The Art of Mathematics
This issue explores Egyptian art with activities that include scaling – brilliant if you are doing an Egyptian project! If you are, see also the Egyptian number system in Issue 4 of the magazine. 
 
Focus on...
From 11 June to 11 July, football fans around the world will be hoping their team makes it through all their matches to win the World Cup 2010. Our focus in this issue is on that long-awaited event.
 
A little bit of history
We look at a potted history of Euclid who is purported to be the most significant of the earliest of the world’s mathematicians. He was the author of the most influential mathematics books of all time, The Elements.
 
Maths to share - CPD for your school
We continue our series on mathematics subject knowledge by exploring subtraction. For this session you may find it helpful to make the NCETM Self-evaluation Tool available for staff to use. 
 
ICT in the classroom
In this issue, we look at ways to make teaching calculator skills and using them in the classroom fun – by coding and encoding messages.
