The present invention relates to a math learning tool using a circular figure puzzle which enables diverse learning activities associated with math including areas, symmetries, similarities, congruences, etc. of figures using a figure puzzle formed in a circular shape. A math learning tool using a circular figure puzzle according to the present invention includes: a taegeuk (yin-yang) figure puzzle (10) in which twelve or more puzzle pieces are formed by dividing a square body (11) with a predetermined size into four areas with the same size using a central horizontal line (12) and a vertical line (13), dividing the square body (11) into a circle (15) inscribed in the square body (11), and dividing the square body (11) into four semicircles (16) having a diameter ranging from a central point (C) at which the horizontal line (12) and the vertical line (13) intersect to points at which the horizontal line (12) and the vertical line (13) cross respective corners of the square body (11); and a leaf figure puzzle (20) in which twelve or more puzzle pieces are formed by dividing a square body (21) with a predetermined size into four areas with the same size using a central horizontal line (22) and a central vertical line (23), dividing the square body (21) into four diagonal lines (24) connecting each point at which the horizontal line (22) and the vertical line (23) cross respective corners of the square body (21), and dividing the square body (21) into a circle (25) inscribed in the square body (21). Accordingly, a math learning tool using a circular figure puzzle according to the present invention is provided to learn various math concepts including areas, symmetries, similarities, congruences, etc. of figures using one puzzle set. |
