FREE for one day, November 2, 2012  – Marble Math Junior for the iPhone/iPad. Kids solve a variety of math problems as they roll marbles through a series of mazes. There are three levels. Level 1 covers addition to 10, equivalent numbers, sequencing of ordinal and cardinal numbers, and shape recognition. Level 2 covers adding coins to $1.00, addition/subtraction to 20, time to the hour, and comparing/sequencing numbers to 100. Level 3 covers money to $2.00, telling time by 15 min. intervals, fractions (1/2, 1/3, 1/4), multiples (2,3,5,10), addition to 100, and sequencing to 1000. Currency can be customized 5 ways: Australian dollar, Canadian dollar, Euro, British pound, & U.S. dollar. Not only does the game supports multiple players but it also allows you to customize specific skills for each player to practice – what a great option! Another great thing about this app  – when a player answers incorrectly, he/she can choose of 3 options: try again, show me, or next problem. Kids earn marbles as they answer correctly and high scores are recorded. Worth downloading!
