My daughter takes 30,000 steps - she is called "Smallsteps" after all! :D
She also moves a lot. I got to about 12,000 the same day (just checked).
Counting steps is a bit silly, but we have made a game out of it for Smallsteps, so she likes checking the numbers and thinks about why it is lower on some days than others.
Probably a great math lesson too, applications of large numbers and quick calculations with lots of zeros. Experiential learning. Nice!
