Line ‘em Up by Classroom Focused Software is great for teaching your child about number order. With this app, your child drags number tiles into their correct order. One down side is that this app has very simple graphics, so some children may lose focus quickly. It is free to download and there are no in-app purchases, so it won’t hurt to try it out. It is compatible with the iPhone, iPad, and iPod touch.
