Developed by a former national university-affiliated teacher, this is the Harappa method of calculation for early childhood and first-grade special needs education. ⭕️ This is educational material for children who dislike math or want to understand it better. ⭕️ The Harappa method allows calculation without using fingers (using fingers for calculation will make it difficult to keep up with math learning in the future). ⭕️ The 4-step process based on math theory is patent-pending. This is exclusive Harappa method material. ⭕️ By manipulating coin illustrations, children develop a sense of numbers. Using 5-yen coins also allows them to understand the logic of the abacus. - Contents: Patent-pending calculation cards up to 10 (addition) ○ Calculation cards (2) ○ Coin card (1) ○ Instruction manual (manga version) ○ Card rings (4) - Target age: Educational material suitable for elementary school students - Theme: Educational material for learning calculation in a fun way ✳︎ Limited sample sale.
