1. *Sung to the tune of "Yankee Doodle Dandy“
Verse 1:
I can count up to 100,
It's so easy if you try.
I can't believe that since we started school
100 days have gone by.
Now let's all count up to 100
Come on try it once with me
We'll finish up with 99,
And last we'll say 100
Let's start out with 1, 2, 3.
(then count as a group to 100 by 1's)

2. Verse 2:
I can count up to 100,
It's so easy if you try.
But this time instead of using 1's,
I'll try to count it by 5's.
Counting this way is much faster
So it doesn't take as long.
First say 5 and then say 10,
And end up with 100,
Come on and join in my song.
(count as a group by 5's)

3. Verse 3:
I can count up to 100,
Now I'll try it once again.
But this time instead of 1's or 5's,
I'll try to count it by 10's.
Counting this way is the fastest,
It is also lots of fun.
First say 10 and then say 20,
End up with 100,
Our song is almost done!
(count to 100 by 10's)

4. One Hundred Days
One hundred days of learning,
One hundred days of fun,
