Let me start by saying, I'm sorry the video is sideways!  I accidentally recorded it the wrong way and it can't be rotated.  (I'll know for next time!) In this video Lexi was using our big floor number line.  All students got a chance to use this.  It helped students to realized they're skipping one number and saying the second number.  For many kids this was a helpful tool in understanding how skip counting works! Keep practicing counting by 2's!
