Who we are

My name is Barbara Schindelhauer.

I have a university background in Business, Psychology and Communication. After several years in Sales & Marketing, my new (and I guess always meant to be) career started during parental leave: I volunteered in my children’s kindergarten, and in 2004 came across Numberland …

Numberland just had this incredible impact on my children Tom (rising 5) and Tina (3) – way beyond numbers!

I wanted to contribute to spread this lovely concept among teachers so that all children of any background had equal chances. The same year, 2004, I founded the ifvl.

Ever since, I have been accompanying many projects and trained many hundreds of teachers, in Germany and internationally. In 2011, I became co-author of the German best selling Numberland handbook (60k copies sold by 2019 and still reprinted!).

I am filled with gratitude for the positive feedback from the field, the international impetus, above all the difference Numberland makes to children!

My name is Dr. Gerhard Friedrich.

I hold a PhD in Pedagogics and teach General Didactics at the University of Bielefeld, Germany. My scientific research focuses on developing didactic concepts for early childhood education. Before, I used to be a teacher for maths, technics, pedagogics, and psychology

From 2003 to 2006, I led a research project on early maths education, initiated by the Ministry of Culture of Baden-Wurttemberg/ Germany. The objective was to develop a concept based on brain research, and early childhood development.

My son Lutz, then 4, was among the first children to shape Numberland. Today, my granddaughter Toni helps to develop new ideas.

Musician Viola de Galgóczy wrote the Numberland stories and composed the songs.

Our Vision

  • Mathematical knowledge and literacy are crucial for education and can only develop on a thorough foundation.
  • Children have a right to grow into their life according to their natural development.
  • Children have an inborn desire to learn and do so by playing in a context relevant to them.
  • Adults are in charge of providing rich and stimulating environments in which children can creatively flourish.
  • We must consequently take the children’s perspective: What do they need? How do they see the world? What can they build upon?

Our Mission

  • Contribute to a joyful, motivating, and successful development of children of all backgrounds.
  • Close educational gaps and ensure equal chances when entering school.

Our Goals

  • Make Numberland available globally and applicable to any environment.
  • Equip teachers with an efficient, down-to-earth tool so they can fulfil their curriculum without compromising children’s needs.
  • Provide a buffet of ideas so that everyone can choose according to their individual needs.
  • Network with professionals everywhere to find and combine ideas for the best impact on children.


A glimpse of international Numberland travellers – and a wonderful proof that children enjoy the same things everywhere and that maths is a global language!
Numberland is also popular among international schools because of their children’s bilingual background.
