A two-page A4 worksheet on Babylonian numbers and base 60 for ages 9 to 14.

Page 1: students convert 12 numbers (for example 125, 276 and 2026) to base 60, writing each place with modern digits from 0 to 59, with space to show their working.

Page 2: a separate answer key with the answer to every exercise.

Ready to print, with no preparation needed. It works well alongside place value lessons, as a history-of-maths starter, or as a way to explain why an hour has 60 minutes. It pairs with the free interactive Babylonian numeral converter on Goofer Games.
