Geometrical steelmodels for school

 

Years ago I invented special geometrical steelmodels for the subject mathematics in school. For more Information or ordering ask at "Lehrmittel-Service H.Späth GmbH" (Ditzenbacher Strasse 26, D-73342 Bad Ditzenbach, Germany). The following two pictures may give You an idea of the steelmodels´ shape.

You can see a pupil of the 6th form with pyramid-parts.

You can see a pupil of the 8th form with other pyramid-parts.
