Grade 4 - Progress in Mathematics

A LOT OF KIDS

There are a lot of kids

Living in my apartment building

And a lot of apartment buildings on my street

And a lot of streets in this city

And cities in this country

And a lot of countries in the world.

So I wonder if somewhere there’s a kid I’ve never met

Living in some building on some street

In some city and country I’ll never know—

And I wonder if that kid and I might be best friends

If we ever met.
