【Product Name】 Number Reading Cards 【Product Description】 These are handmade educational materials that help children learn the rules of reading numbers and the concept of place value. By arranging the cards aligned to the right, children can learn to read numbers up to four digits. Children tend to grasp numbers up to around 30 easily through counting familiar objects. However, for numbers beyond 30, verbal cues are needed to help them focus on invisible numbers or those they don't usually pay attention to. Once children can count up to around 30, it's beneficial to advance their understanding of the decimal system, as it will be more applicable and helpful in their studies. Let's use these number cards to introduce the rules of reading numbers and the concept of place value, deepening their understanding while fostering familiarity with numbers. 【Contents】 - Total of 36 number cards from 1 to 9000 (Laminated) Size: One 4-digit card is 4cm x 16cm *Case is not included.
