36 units, six elementary levels
Practice number sense, place value, arithmetic, fractions, decimals and ratios. Korean units follow the number-and-operations sequence of Korea’s revised 2022 curriculum. Other languages use six elementary learning levels.
Different ways to practice
Multiple choice, balloon popping, card placement and counting activities make each question a little different. Visuals show fractions and number concepts alongside the written problem.
The method before the answer
A step-by-step worked example introduces each new unit. Incorrect answers get another try. After two incorrect attempts at the same problem, a hint explains the method while keeping the answer hidden.
Learning records stay on the device
