A Froebel star (German: Fröbelstern) is a Christmas decoration made of paper, common in Germany.
[3] The three-dimensional Froebel star is assembled from four identical paper strips with a width-to-length proportion of between 1:25 and 1:30.
[5] The star can be considered a form of origami,[6] because it is made of identical paper sheets and assembled without glue.
[3] The Froebel star carries the name of the German educationist Friedrich Fröbel (1782–1852), founder of the Kindergarten concept.
He encouraged the use of paper folding in pre-primary education with the aim of conveying simple mathematical concepts to children.
