Grade 4 - Progress in Mathematics

(Marvins-Underground-K-12) #1
Is Six Times One a Lot of Fun?
Is six times one a lot of fun?
Or eight times two?
Perhaps for you.
But five times three
Unhinges me,
While six and seven and eight times eight
Put me in an awful state
And four and six and nine times nine
Make me want to cry and whine
So when I get to twelve times ten
I begin to wonder when
I can take a vacation from multiplication
And go out
And start playing again.
