Hi,

On Number Line Pratice, the questions are replicated some times....
On my first pratice on Addition, I see a little random questions, but it's not happen on Number Line.

What happens was that: It's ask twice to move yellow point to number 4 and the ask 3x to move yellow point to -4.

I'm just want to inform to better this pratice

see ya
