Adding Doubles Plus One Poem – Mr. R.'s World of Math

Doubles + 1

adding doubles + 1

Doubles! Doubles!
Doubles are fun,
But much better yet,
Are doubles plus 1!
4 + 4?

You always get 8,
Let’s memorize that,
‘Cause doubles are great!
So 4 + 5,
Is just 1 more!
You gotta’ get 9?
Just check to be sure!

4 + 4,
Plus 1 is 9,
Doubles plus 1,
Saves you time!
Know a double?
Add 1 more!
Doubles plus 1,
That’s the score!
Doubles, doubles,
Doubles are fun,
But much better yet,
Are doubles plus 1!
