Objective

Students will convert between many units of time.

The goal is to get students thinking about what makes sense. Practice estimating. Practice interpreting numbers. There are so many directions you could take this.

Inspired by a question asked in Accessible Mathematics.

Steps

  1. I announce that I've just turned 341,640 old and ask students to determine which units make the most sense.
  2. I provide a little scaffolding, showing why months is a very unlikely unit.
  3. Then, I ask students to determine how old I am in Saturn years.
  4. After revealing my findings, I ask a final question: how many flies' lifetimes old am I?
  5. I reveal my answer and then open the door for students to use other unusual units of time to express my (or their!) age
