Attention strengthening set for 7 years old. Dgs 7 year old set consists of 3 books. Each book consists of 156 pages. The order of the books should never be perceived as a ranking of difficulty. In each book, easy and difficult exercises that children can do at their age are listed together. Difficult exercises are not given over and over so that children do not get bored and give up on the book. Each book contains sticker exercises presented along with age-appropriate exercises. Sticker exercises should be applied to children through a reward system. As we solve the attention exercises, the next sticker exercise should be done so that our children can study with pleasure.
