Grade 4 - Progress in Mathematics

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.
