2:36A song. A few new discoveries.
Arrange biscuits into equal groups and discover factors, factor pairs and numbers with lots of ways to divide evenly. Start with 12, try 24 and 36, then find out why 60 and 360 are such useful numbers.
The record-breaking numbers in this song have more positive factors than every smaller positive whole number.
Made for curious kids around ages 6–12 and the grown-ups watching with them. Music and animation created with AI tools under Mike Sego’s direction. YouTube’s video description includes the release notes and credits.

Smarty Party!
Welcome to the No-Leftovers Club.
We take arranging biscuits very seriously.
Twelve little biscuits, how shall we arrange?
One row of twelve is long and rather strange.
Two rows of six, three rows of four,
Turn them round! We've found some more!
One, two, three, four, six and twelve,
Those are twelve's whole factors, put them on the shelf!
No leftovers! Everybody fits!
Make another row of our little biscuit bits!
No leftovers! Nothing left behind!
A factor makes equal groups, what a tidy little find!
Twenty-four has plenty: two times twelve will do,
Three times eight, or four times six, another lovely view!
Thirty-six makes six by six, a biscuit square so neat,
Sixty splits in fives and tens. Don't eat the counting sheet!
No leftovers! Everybody fits!
Make another row of our little biscuit bits!
No leftovers! Nothing left behind!
A factor makes equal groups, what a tidy little find!
Three hundred sixty, seven hundred twenty,
Five thousand forty! Now that's biscuit plenty!
Some numbers break the record for the factors that they've got,
More than every smaller number. Oh, that's a useful lot!
Sixty seconds in a minute, sixty minutes make an hour,
Three hundred sixty degrees go round, that's dividing power!
No leftovers! Everybody fits!
Make another row of our little biscuit bits!
No leftovers! Nothing left behind!
Who ate one?
We are now the Eleven Biscuits Club.
Much less flexible.
