The educational poster series is designed with bright colors and friendly fonts as the core, targeting children's cognitive characteristics. Each poster adopts an intuitive layout combining images and text, such as "MY BODY" uses rounded fonts to mark body parts, and "SHAPES" uses colorful illustrations to distinguish geometric shapes. The multiplication table with soft tones avoids visual fatigue, and the weather poster uses corresponding colors to strengthen the memory point. The currency unit is visually presented through the physical illustrations of silver coins and green banknotes, which intuitively presents the combination logic.
