Teaching the Tricky Teens

If you teach Kindergarten (or even first), you know the routine of teaching the "teen" numbers.  It can be a daunting task and has been for me, until I discovered this little gem by Harry Kindergarten on YouTube:

With this video, I have done...

• Movement: song/dance with motions
• Number lines (moving a see through colored chip over the teens)
• Holding up numbers as they are sung
• 10 frames

The kids absolutely love this little rap and request it often, which always cracks me up.  Harry Kindergarten also does other songs- I've used the 2D shape rap, as well as the 3D shape rap, too. 

Any other ways you teach the teens in a fun but repetitive way?
