Twelve is the number of eggs in a box and of months in a year. This 3rd grade dividing big numbers by 12 worksheet uses it as a divisor in six problems. The numbers to share are 144, 132, 72, 36, 120 and 84, and each one is a division with no remainder, with answers from 3 to 12. A cheerful purple dinosaur sits at the bottom of the page. Page two shows every bracket in full, and this time it also writes each answer on the line next to the problem.
