Created by a parent and a primary-school teacher, CrazyMinute is a fun math quiz on basic facts with a myriad of problem variations and a unique interface. iPad users also have an additional game variation to choose from: see the companion app MathNight, exclusively for iPad. This 60-second quiz incorporates playful sound effects along with the unique digitBar™ interface for easily entering answers. With one finger or thumb dedicated to the ones place and one for the tens place, students can quickly enter and correct answers while reinforcing an important understanding of how numbers are built. Created for everyone, there is no text used anywhere in the game: all interaction is stripped-down to the essential meanings of numbers, math symbols, and a few colored buttons, making it perfect for early readers and parents worldwide. Each game reviews skills in addition, subtraction, multiplication or division; players can choose quizzes from a range of random values (from 0 through an upper-bound) or against a fixed value (to focus on just “your 8s” for example). Designed for positive reinforcement, problems simply remain on the screen until answered correctly, so there is no penalty other than lost time for typos or incorrect attempts. Whatever skill level you work on, practicing basic math facts helps all math students create a solid foundation for working easily with all types of mathematics, and will help students progress quickly through the “Mad Minute” quizzes given daily in many schools’ early grades. How many can you answer, before time runs out?
