The following lab is based on the traditional English nursery rhyme:

As I was going to St. Ives,

I met a man with seven wives;

Each wife had seven sacks,

Each sack had seven cats,

Each cat had seven kits.

Kits, cats, sacks, and wives,

How many were there going to St. Ives?

Move back to the original nursery rhyme with 7s meeting 1 man:

1: If each kit wore 7 mittens what is the total number of items?
