Here are the numbers one through nine on a diagram we call a number line
They're represented by lengths that mark with points spaced equally apart
Now if we extend this number line, one whole number to the right we'll find
The next number that we'll mark is ten. Now let's extend it again and again
Twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety
Then my ride ended at one-hundred, but the pattern continues forever ahead
There are many instances where numbers are shown as distances
Represented on a number line helping us find sums and differences
Woah, woah, oh, oh, Woah, woah, oh, oh, Woah, woah, oh, oh
We can jump forward on number lines to solve problems with addition signs
Let's add eleven to twenty-nine, jump one and then ten, forty is the sum we'll find
And we can subtract eleven to rewind, which will take us back to twenty-nine
We can jump backwards on number lines to solve questions with subtraction signs
Let's subtract twelve from twenty-five, jump back ten and then two, thirteen is the difference we'll find
Now add back twelve to thirteen and we will arrive at a sum we've seen, twenty-five
There are many instances where numbers are shown as distances
Represented on a number line helping us find sums and differences
Now here's just one last remark about the distance between each mark
Which we can call spaces to be literal
But their correct mathematical name is interval
There are many instances where numbers are shown as distances
Represented on a number line helping us find sums and differences
Woah, woah, oh, oh. Woah, woah, oh, oh. Woah, woah, oh, oh
