Zählen, Rechnen, Messen

Im Lauf der Jahrhunderte haben die Menschen sich immer schlauere Methoden ausgedacht, um unsere Welt besser zu verstehen, Städte zu bauen, den Weg nach Hause zu finden und vieles mehr. Zählen, Rechnen, Messen erzählt die Kulturgeschichte der Zahlen und wie sie die Welt verändert haben.

Wie sollten wir drei Kugeln Eis bestellen? Warum hat eine Minute eigentlich 60 Sekunden und nicht 100? Woher kommt die Null und welche Sprache sprechen Computer?

Zahlen sind überall! Zählen, Rechnen, Messen eröffnet Kindern die faszinierende Welt der Zahlen und erklärt, wie sie uns durch unseren Alltag begleiten. 3 - 2 - 1, los!
