학생용 플래시카드

Create a set of [number] flashcards for students in [age/grade] who are learning [topic] in [subject]. Objective: [learning objective]. Each card should teach ONE single idea. Design each card with: FRONT * term, question, concept, symbol, or image. BACK * short answer or definition; * one-sentence explanation; * simple example when useful; * small visual aid if it improves understanding. Keep exactly the same visual system across all cards: typography, margins, proportions, hierarchy, and graphic style. Make them easy to recognize and read quickly. Avoid long definitions, secondary information, complex backgrounds, or purely decorative illustrations. Organize them so they can be easily printed and cut out on [A4/Letter]. When finished, check that there are no duplicated concepts and that the [number] cards adequately cover the topic.
