The trend of elementary mathematics education, with the importance of the basic learning market increasing!
The learning environment is becoming increasingly specialized and shifting towards emphasizing quality over quantity.

[5-Step Basic Academic Skills Enhancement Project]

According to the Korea Institute for Curriculum and Evaluation, the proportion of students with an average academic ability of level 3 or higher has dropped significantly, and as a result, basic math skills have declined and the number of students in the upper-middle and upper-middle levels has also decreased.
We provide a solid curriculum from the basics to assessment, from learning keyword concepts to basic word problems for each unit, final assessments, and concept notes at a glance.
