The Tens Tree

There was a sign,
On a tree,

You must be 10,
To play on me!
You must be ten,
To climb up high,
You must be ten,
To reach the sky!
I was only 9,
Couldn't wait,
'Til I was 10,
Right there and then!
I sat and thought it out,
And a plan began to sprout,
I decided,
It was time for little sis...
She was 1 year old,
And the truth, I had been told,
Is that 9 + 1,
Would go a bit like this...
The sum of 1 and 9,
Is a 10 every time,
And 10 is what we used,
To fool that tree...
With little sister there,
My smile filled the air,
And the 10 we made together,
Set us free...

 Math Challenges If there are 9 seeds and 4 of them sprout into trees, how many seeds did not sprout? If the sign in the poem said I have to be 14 years old to climb the tree, how many more years would I have to wait to climb it? (I'm already 9) If a tree is 18 feet tall, and grows another 7 feet, how tall is the tree?
