Description

Beschreibung. J&e Abdeckbare Rechentafel dient wie die Stautnersche Tausender- igafel der Veranschaulichung des zahlenraumes von 0-1000. Ihre Verwendung findet sie in den Unterstufen an Volksschulen. Bei ätautner sind auf der Tausendertafel 10 Husderterstreifen neben- einander gereiht, jgit Holzstäbchen auß die zu zeigende Zahl ab- gegrenzt werden. Dabei bleibt jedoch der ganze Hunderter sicht- bar. Die Abdeckbare Rechentafel hat den Vorzug, daß die nichtge- wRinschten Biserpunkte der Hunderterstreifen durch das Abdecken vermittels eines Bandes unsichtbar werden. Bei Stautner ist es der Lehrperson nur möglich mit 2 Stäbchen zu arten außerdem leidet die Sichtbarkeit der Zählen auch dadurch, daß die Lehr- person mit ihren Händen in das Zahlenbild greifen muß. Bei der Abdecktafel können die Bmaderterstreifen in beliebiger Zahl mühelos abgedeckt werden, ohne, daß die Lehrkraft einen Teil des Zahlenbildes verdeckt. Damit entfällt die Arbeit des Fest- halten der Stäbehen da die Abdeckbänder mechanisch stehen- bleiben. Schutzanspruch.
