Counting helper

This is a tool to help the young start counting above 10. Created it for my daughter now when she is staring school. Ass you see on the GIF, you slide in from end to end and numbers from 0 to 99 If you glue the 2 “foots” to the bar, it stays in place better on the number plate It's not an original idea. Have seen this in versus versions online fore years.
