An app to teach kindergarteners Mathematics

Hi I'm making an app that teaches Mathematics,in the app the user answers a series of multiplying mathematic questions for a period of time,for every correct answer there will be additional score,after the period of time it initializes another screen and it will call values from the firebase to check if the score is higher than the scores in firebase and then let user to enter his/her name and then save both the name and the score into the firebase,there can only be 5 highscores too,are there any other tutorials that i can refer to for this
