Vusi Ndlela was a maths and science teacher for 12 years. He left the profession in 2005. Now he's invented a much-needed teaching tool called Fraxion Master. It teaches students in Grades 3 to 7 fractions in a simple way. To prove that his invention does work, Vusi needs 200 prototypes in 5 schools. He has located a manufacturor but the mould alone costs R250 000. If you can help Vusi with sponsorship, please phone him at 078 250 8542.
