A song that tells the story of how Mr. R. learned about multiplying by ten...
Don't underestimate the value of learning this simple concept! It's especially important in understanding place value in multi-digit multiplication!

LYRICS
Every time,
I 'timesed' by ten,
Got it wrong,
I'd try again...
Still I couldn't ever get it right,
Times tables trouble,
Day and night...
Old man said,
Hen can fix...
I laughed out loud,
Old man tricks...
Hens don't know,
Their 5's or 10s,
They don't know,
Because they're hens...
Just go give,
Hen a try,
Said the man,
Winked his eye...
I guess it couldn't hurt,
Couldn't hurt you know...
(chorus)
When you multiply it,
Multiply it by 10,
You drop a single zero,
On the end...
When you multiply it,
Multiply it by 10,
You drop a 0 on the end!
When you multiply it,
Multiply it by 10,
You drop a 0,
On the end...
Took my math,
To hen's pen,
Looked at her,
Laughed again,
This was silly,
I knew hens,
Don't know 5's,
Don't know 10's...
Homework said 10 x 6,
I couldn't think of teacher's tricks,
I couldn't multiply,
Multiply by 10...
10 x 6,
Hard for me,
Should of been real E-Z,
Can hen solve it,
10 x 6,
Let's see!!!
(chorus)
Hen grabbed pen,
And hen grabbed pad,
Wrote a 6,
And looked real glad,
She turned around,
An egg she laid,
Right behind the 6,
I was amazed...
Read her answer,
Right out loud,
Old man's hen,
She felt real proud...
The egg made zero,
After 6,
Egg made it 60,
Hen knew tricks...
Then I knew,
I knew right then,
Old man was right,
He was right again,
You should never, never, never,
Never doubt a hen...
(chorus)
I don't know why I'm watching this since I'm a junior in high school.. Or even why I'm asking this but; what if you're multiplying a decimal? I.E. 2.1 x 10.. You just drop a zero? 2.10? Nooooo :)

@alexfs95 that's true Alex- I guess the junior high version would say, just move the decimal one place to the right...

@thesnix thanks- might seem insignificant to you, but means a lot to me- I'm glad he was able to learn something from the vid and hopefully it will help him remember this simple but quite important concept! Thanks again. Mr. R.
