How old are you?


We usually give our ages in years, but that isn't very precise is it?  In this activity students find their age in days, hours and minutes.  First students take two minutes to estimate their age in days, hours and minutes.  When they make their estimates, consider sharing and recording estimates as a class. Even though students will slightly vary in age, their estimates should be in the same relative range.

This is a great opportunity to discuss estimation and reasonability.  Follow this estimation & discussion with actual calculations.  Students can use any method that makes sense to them.  Depending on grade level, you might use this activity as a way to introduce or review unit conversions (see the example from the Arizona CCSS flip books below):

Finally, students can double check their estimates & calculations using this TI calculator:
