This is a fund raising event. Please make a donation if you possibly can. $10 from every participating school would train 2 more teachers in disadvantaged communities. $30 each would mean AIMSSEC would have bursaries for 6 more teachers.

Even if every child donates 10p, 10 cents or 10 euros, we would raise $4,000 for our partner cause, whose founder has helped coordinate this world record and helped with the resources. The cause is AIMSSEC – empowering children in disadvantaged communities to Rise Up from poverty through excellent, sustainable education. You will find a donation link and more information at
