Die Thurmuhr: eine Rechen-Fibel für kleine Kinder

A picture-and-rhyme primer that introduces the numerals one through ten by pairing each number with a brief verse and the image of a clock strike, then reinforces learning with simple arithmetic problems, Roman numerals, and basic fractions. Each number is illustrated with everyday scenes or moral reminders and followed by exercises in addition, subtraction, multiplication patterns, division and equitable sharing. Visual prompts and worked examples show halves, quarters and eighths, counting with objects, and short word problems designed to make early numeracy concrete and practice-oriented for young children.
