Addition Facts To 20 Flashcards

Calculation skills are the foundation of mathematics. We designed this set of Addition Facts to 20 Flashcards for addition and subtraction within 20 with one clear goal: to help children build strong foundational skills through fun and engaging activities, making mental arithmetic feel natural and automatic.

Our Addition Facts to 20 Flashcards design follows the principle of "small steps, quick progress." We begin with the most intuitive addition and subtraction within 10, using illustrations of apples, balls, and other familiar objects to help children develop number sense. Then we gradually move on to addition and subtraction within 20 without regrouping, and finally to the more challenging addition with carrying and subtraction with borrowing. On key cards, we include problem-solving tips, such as visual guides for the "making ten" method, clearly illustrating the thinking process so children can understand it at a glance and no longer feel intimidated by complex calculations.

We place great importance on product durability. The cards are made of thick cardstock that has been repeatedly tested by our experienced craftsmen. They are sturdy enough for a child to hold with one hand without bending, and the edges do not fray even after repeated use. One elementary school math teacher ordered 400 sets for the entire grade at once. At the end of the semester, she sent us photos. Although the cards had been handled hundreds of times by students, they were still in excellent condition. She said, "The quality of your cards is even better than the textbooks I purchased!"

Our factory is BSCI certified, and our products meet international child safety standards. You can confidently market them in demanding European and American markets. Whether for bulk purchases by kindergartens or as supplementary teaching aids, we ensure that every card is safe, durable, and beautifully printed.
