About the Author

Eddy Krajcar is a primary school teacher and the author of the global best-seller New Wave Mental Maths.

At the start of his teaching career in 1993, Eddy noticed that many pupils had gaps (or areas of weakness) in their conceptual knowledge. He realised ‘teachers, and the resources they used, tended to teach one concept at a time. Content previously learnt was going unpractised and eventually was forgotten by the next school year.’

As a result, Eddy set himself the task of finding a solution that could be applied in schools. With a passion for problem-solving, as well as in-depth knowledge of the curriculum from years of research, Eddy’s educational background and experience were invaluable when it came to writing the New Wave Mental Maths series (first published in 1999).

After decades, New Wave Mental Maths is still a global sensation that continues to effectively deliver engaging reinforcement of mathematical content using the time-tested method of spaced learning.

Eddy is enthusiastic about the revised series being integrated into classrooms across the world.
