Free interactive math game: Leap Year Check — Is 2024 leap?. Part of the Units & Time category on MathKite.
Taken from the generator that powers this exercise. A fresh set appears every time the page is opened, and the printable worksheet holds ten of them.
Deciding whether a year has 366 days.
A year is a leap year if it divides by 4, unless it divides by 100 — but century years divisible by 400 are leap years after all.
2000 divides by 400, so it was a leap year, while 1900 was not.
Using only the divide-by-four rule. It gets most years right and every century year wrong.
