Features
Read full description

An abacus is a tool used to perform mathematical calculations and is widely accepted as a helpful learning aid for students. However, the learning curve can be challenging not only for many students but also for teachers and parents. Practice2Master Abacus helps address this learning difficulty by making abacus learning an interactive experience. This app allows students to take lessons, practice skills, and monitor their progress by completing quizzes and drills, all at their own pace. The Practice2Master Abacus app can be used as a supplement to classroom instructions in which teachers can assign practice tasks or drills to students. It may also be used as a self-learning tool that includes systematic instructions and practice to help students start from the basics and become proficient abacus users. Not only is this app a great tool for students, but it can also be used as a reliable reference for teachers and parents who need to refresh themselves on abacus calculations. Features/Benefits: • Twenty-two progressively ordered short lessons on how to use an abacus to do addition, subtraction, multiplication, and division • Abacus operations that are explained in great details using purposefully chosen examples • Patterns of hand and finger movements that take into consideration the learning characteristics of young students and students with visual impairments • Full compatibility with screen readers; high-contrast colors and large print letters and numbers • The ability to practice what you learned in lessons using app-created problems or problems created by your teachers • Dynamic assistance from the app during practice • Progress monitoring through lesson quizzes and drills • Quiz or drill reports for personal reference or to send to teachers • Customized problem lists that teachers can create and send to students for practice or drill. • On-screen abacus for calculation operations
