Area Model Multiplication

A farmer was planting green beans
In fourteen rows of fifteen
The area model is how he thought
About the number of plants he'd got
First he multiplied ten by ten
And wrote one hundred with his pad and pen
Then he multiplied ten by five
There were fifty more plants coming alive
Then ten times four equals forty
And just the bottom corner was empty
So he multiplied five by four
And ended up with twenty more

Split up the place values in multiplication
Multiply the tens to get the foundation
Then the other place values get multiplied
Add the partial products up
And check your work twice

Then the farmer planted black beans
In twenty-two rows of fifteen
To find out how many plants he had
He drew the area model on his sketch pad
He did twenty times ten
And wrote two hundred down
Then ten times two
And twenty is what he found
Twenty times five was one hundred
And then Five times two equalled ten
He added two hundred, one hundred, twenty and ten
The sum was three-hundred thirty
He checked it again
So there are three hundred thirty black beans
In twenty-two rows of fifteen

Split up the place values in multiplication
Multiply the tens to get the foundation
Then the other place values get multiplied
Add the partial products up
And check your work twice
