① These cards are for number composition and decomposition for numbers 2-10. By repeatedly practicing with these cards, children can memorize the decomposition of single-digit numbers from 2 to 10. ② In addition problems with carrying over, it's necessary to think about how many more are needed to make 10, and to decompose numbers. If this isn't done smoothly, children will struggle with addition. For example, in the addition problem 7 + 8 =, we think about how many more are needed to make 10 from 8. It needs 2 more to make 10. Next, we think about how to decompose 7 into 2 and what number. 7 can be decomposed into 2 and 5. In this way, we calculate 7 + 8 = 15. The key to solving addition problems with carrying over is being able to smoothly determine how many more are needed to make 10 and to decompose numbers. ③ There are 45 types of cards for decomposing numbers 2-10. You can choose cards that suit your child and practice with them. By repeatedly practicing with these cards, children will memorize the decompositions, be able to decompose numbers smoothly, and improve their carrying-over skills. These cards can also be used for "cherry blossom calculation" (a visual method for addition and subtraction). ④ The front of the cards features illustrations of apples, which serve as hints for finding the answer. The answers are shown in red on the back of the cards, making them easy to understand. The apple illustrations are also printed on the back, so children can check their answers while thinking. (Version 1, which does not have apple illustrations on the front, is also available.) ⑤ There are also 9 types of "How to Make 10" cards, from 1 to 9, which can be practiced repeatedly. ⑥ You can also practice addition and subtraction by covering a part of the answer side (back). ⑦ Printed on paper that is almost the same thickness as a postal postcard, each card is carefully processed with a business card-sized lamination film. They are durable and resistant to dirt, even with repeated use. ⑧ The size is business card size: 5.5cm (vertical) x 9cm (horizontal). ⑨ Although we create these cards with care, they are printed with a home printer, so there may be some slight blurring or minor misalignments in the lamination.
