Deca-… Jan. 2020

Hello everyone,

Welcome back to school! I hope you enjoyed your time off, whether it was long or short. On January 1st we celebrated the new year… but it was also the start of the 2020’s. It is the start of a new decade!

Deca- is an English prefix that means x10. For example, at the Tokyo Olympics there is an event called the decathalon, which has ten sports. When we talk about time, a decade is ten years.

It is common to use decades in English conversation. I enjoy sports, so I might say “Michael Jordan was the best basketball player in the 90s,” or “I grew up in the 80’s in Vancouver.”

Last decade saw the rise of the smarthphone around the world. What do you think will happen this decade? Let’s find out together!
