Great video! @4:53, you say you go to four when it should be going to 8 and then 4. Just helping you out, as you have helped so many people out.
Any chance you can create a number line video with questions on how to locate say 3/8 on a number line or find which point is greater than -7.5 but less than -2.5 on a number line where not every point was labeled. Say 0 to the first point was not labeled but the second point were 5.
Thanks, Sal!

I think using the old style odometers for demo purposes would work well.
Change the 0-9 to other characters and show it still works..., then do wheels with 16 symbols, then 2. Show the 3 odometers side by side clicking around and how they each represent the miles traveled.

Sal, you're crazy intelligent AND your handwriting could put any 4th-grade homeroom teacher's to shame!
