I had printed out Number Lines long time ago from the Internet but it got torn and the condintion was not satisfying to me after taping it. I sat down and created this set of Number Lines. Now, Nathaniel participates more playing board games whith us and he likes the color Number Line the most.
I printed out few of these lines and I put them in boarding game boxes when they were needed. This way Nathaniel always has it and we don't spend time looking for it in which board game we left it last.
These lines are simple but very effective.
