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
