Our Mission
The problem
Education research studies* have consistently shown that very often students do not understand the tools that they use in geometry and for measurement, such as rulers and protractors. An underlying cause for this problem is that students often have only a limited and fragmented understanding of what it is that they are trying to measure; such as the concepts of angle, length, area and volume.
Our solution
Our mission at OLM is to develop tools and their associated publications that can facilitate deep, flexible, understanding of geometry and measurement by the students who use them.
