About the song:

The overnight delivery service is scurrying around to get their packages to all of the stores in the city before sunrise. As they drive, they rap and sing about adding and subtracting the decimal values of their various packages. The NUMBEROCK night shift crew line up the tenths, hundredths, and thousandths when adding and subtracting decimals, and so should you!

Ultimately, we hope you find this a fun way to learn decimal arithmetic.

Three hundred one-thousandths minus two-tenths:
line up the tenths, hundredths, and thousandths.
When right of a number there’s an empty space,
writing zeroes can help by holding the place.

The decimal point drops directly below,
so that the points line up in a row.
Subtract each place value to find the difference
equals one hundred one-thousandths.

To find the sum or difference
it just makes sense
to line up the tenths,
hundredths, and thousandths.

To add five-hundredths and six-thousandths:
line up the place values with confidence.
When right of a number there’s an empty space,
writing zeroes can help by holding the place.

The decimal point drops directly below,
so that the points line up in a row.
Add it up, and fifty-six hundredths is the sum;
it feels so good to know this problem is done.
If after you line up the place values,
there are spaces to the right that you didn’t use,
you can choose to write zeroes, and the content
will have a value that is equivalent.

Aligned With:

TEKS Supporting and Readiness Standards
The student is expected to add and subtract whole numbers and
decimals to the hundredths place using the standard algorithm.
The student is expected to compare and order decimals using concrete and visual models to the hundredths.

Common Core Standard
4.NF.C - 4.NF.C.7
Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole.
5.NBT.B - 5.NBT.B.7
Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
6.NS.B - 6.NS.B.3
Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. 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'll be releasing new songs and videos regularly until eventually addressing all the math skills and concepts that a Common Core Curriculum demands from 1st Grade to 2nd Grade, and even 5th Grade to 6th Grade.

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.
