Have you ever wondered how many steps you take in a day? The answer isn’t obvious. You might be running all over a soccer field for an hour, then sitting and eating a snack the next. And you’re going to sit around more on a rainy day than a sunny one. But even with all that, scientists have found that healthy kids take about 9,000 steps a day. So what does that come to in a year — or your whole life so far? That’s where math can help!

Wee ones: If you step with your left foot, then your right foot, then your left, then your right…how many steps have you taken?

Little kids: If you took 9 thousand steps yesterday and 7 thousand today, on which day did you take more?  Bonus: If you take 2,000 steps each day, how many do you take in 5 weekdays? Add up the thousands!

Big kids: If you take a whole 10,000 steps a day, how many does that come to in 1 365-day year? (Hint if needed: As a first step, what if you took just 1,000 steps per day?)  Bonus: Now figure out about how many steps you’ve taken in your life! You can round off to years or half-years to estimate. And remember, you don’t start walking at birth!
