What's this?

I use this number line in online lessons.

Students must adjust the slider according to the position of the number on the line.

This can, for example, be helpful when rounding numbers.

The svg is integrated with the HTML tag. The number line can be defined with the parameters value (number on the slider), min (left value), max (right value) and tolerance (placement accuracy).
