Erste Anleitung für Kinder mit Zahlen umzugehen, um sie in etwas zum Kopfrechnen vorzubereiten
An 1797 German primer by Johann Melchior Möller, published by Beyer und Maring, teaching children to handle numbers as preparation for mental arithmetic. The two plates show circular number arrangements with numerals scattered around rings, and a row of dice-pip patterns grouped by value under the heading 'Zur Seite 23 gehörig'. A designer could take from them the idea of numbers as arranged, countable patterns, with the dot groupings and ring layouts offering simple modular structures for diagrams or pattern systems.
