Seven one-page worksheets for ages 7 to 18. Each one is filled in with today's numbers from our live tools when you open it, with teacher notes and answers worked out from the same numbers. UK versions print on A4, US versions on Letter.

When you open a sheet, the numbers are taken from the live tool and printed with the time. Print a class set in one go so every copy matches the teacher notes. If a number is not available, the sheet leaves the boxes blank for the class to look up instead: it never prints an old number.
