Ratings and Reviews



This app is just okay. My son is 5 and can do simple addition but I've never really taught him about the number line. We have been using manipulatives. As far as the number line concept goes this is good. As a parent you still have to explain the game and sit next to your kid because the instructions aren't great. The robot voices can also be hard to understand. I don't know I would buy this game again. It's basic and not that great and hard to understand the robots talking. My son gets kind of bored with it easily.

Doesn't work

GCCA mom

The app allowed me to enter a players name and create their robot. Then it got stuck "blasting off" and I had to close out. This happened repeatedly. Waste of money!! Very disappointed we were not able to use a single feature on this app. It should be removed from the App Store :(

Developer Response

Dear GCCA mom Thank you for your feedback regarding our app Robo Math Number Line Galaxy back in 2016, sorry not to have gotten back to you sooner but the 'reply to reviews' feature is new to us, and is incredibly helpful! I'm really sorry you have had a problem with the game. Your feedback alerted us to the problem with the update on these devices, we updated the app further and have not had any reports of problems since. Your little one is probably much bigger now and doesn't need number line practice any more but if you do go back and give it a try again do let us know how you get on! Apologies again and do feel free to contact me further at Thanks again for your feedback, its so very helpful, Vicky Carpenter Teacher & Director of MadeByEducators

Gets stuck


My kids cannot play this as it gets stuck on creating the robot. I do not recommend.
