Aravinda,
I think cardboard and pins will work but may not hold up as long. Let me know how it works!

Erika, We use it just as a visual to show patterns in multiplication. There are a lot of “light bulb” moments when you get to the beginning of a pattern and it starts again. Plus it gives them a kinectic activity and a little hint while they are reciting skip counting songs or times tables. We don’t really keep track of the tens or hundreds place. I hope that makes sense.
