### In the lessons

In maths and history lessons, pupils learn time words: a decade is 10 years, a century is 100 years, and a millennium is 1,000 years; timelines may show several millennia. In science, «over millennia» means over many thousands of years, as rivers carve valleys. Phrases: «a new millennium», «for millennia», «the turn of the millennium».

### Note

Spelling trap: double l and double n: millennium. Plural: millennia (more common) or millenniums. In maths: 1 millennium = 10 centuries = 100 decades = 1,000 years. «Millennial» as a noun means a person born around the end of the last millennium.
