# Marble Math

FREE today only – Marble Math. This educational app for 9 – 12 year olds was selected by Apple as New & Noteworthy. Kids solve a variety of math problems as they navigate their way through a series of marble mazes. Concepts included are addition/subtraction, multiplication/division, adding/sequencing fractions with different denominators, factoring, adding/subtracting negative integers and more! The game supports multiple players and it allows teachers to customize specific skills for each player – what a great option! Another great thing about this app – when a player answers incorrectly, he/she can choose one of 3 options: try again, show me, or next problem. Kids earn marbles as they answer correctly and high scores are recorded. This game blends fun with the practice of common core skills. Worth downloading!
