Mathematics is one of the subjects taught since elementary school education. Geometry and measurement are aspects of basic competencies found in elementary school mathematics learning ranging from class I to class VI. To make a child have good geometry measurement skills, the teacher (parent, teacher or family) must have a means or media that can train children's geometry measurement skills in an interesting and fun way.
