Watch as Farmer Maslow takes us on a tour of his farm by the sea as he plants his new crops. As he plants a field of green beans, he’ll be showing us how to multiply two-digits by two-digits using the area model. Also known as the Singapore Method, using geometric models to show a deeper understanding of the mechanics of multiplication is something that is a regular part of Farmer Maslow’s everyday life.

VERSE ONE
A farmer was planting green beans
in fourteen rows of fifteen.
The area model is how he thought
about the number of plants he 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.

CHORUS
Split up the place values in multiplication.
Multiply the tens to get the foundation.
Then the other place values get multiplied.

VERSE THREE
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’s what he found.
Twenty times five was one hundred, and then,
five times two equaled ten.
He added two hundred, one hundred, twenty, and ten;
the sum was three [hundred] thirty; he checked it again.
So, there were three hundred thirty black beans
in twenty-two rows of fifteen.

http://www.NUMBEROCK.com is a provider of educational videos for kids which was founded by an innovative 5th Grade teacher who envisioned a new kind of classroom where students got energized for math class. Parents of his students even noticed their children singing mathematics songs around the dinner table well beyond school hours.

Seeing his students so enthusiastic when it was time for math was welcome, to say the least! But the epiphanous moment was when students were singing math songs all-day long like they were in the American Top 40!

We dare to believe that these math songs + videos can actually identify with elementary school children’s increasingly finicky perception of what is cool and trendy. While each song is diverse in composition, most fit directly into the modern musical genres that excite young kids: genres such as Rap, R&B, Pop, Hip-Hop and even Reggae!

Our main goal is to make teaching and learning math more fun and more interactive. SchoolHouse Rock! has done this in other subjects for us in the previous generations, and many of us still enjoy watching their YouTube Videos which teach us about Government, Science, and English amongst other subjects.

This video addresses the following Common Core Standards:

4.NBT.5
Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

5.NBT.B.6

Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
