Intuitive
This is an excellent teaching tool. I’m a math tutor, and it’s definitely one of my more often used apps. I do wish I could make the number line vertical though. I can imitate it by rotating my iPad, but that makes the numbers harder to read, and some of my students are dyslexic. Also, if there were an option to pay a couple of dollars to get an add-free version I would. The ads aren’t too intrusive, but I’d be happy to support the developers and get a cleaner version.
