Gratitude notebooks are a tool of Positive Psychology. The aim of this project is to teach Elementary school children to make a notebook that encourages the habit of giving thanks daily; a space for reading, writing, and drawing. The construction of the notebook carries with it the transformation and awareness of the person in the positive, in what we can thank for each day lived, in what is a gift and we take it for granted. We review the activity progress after one month. the notebooks will be analyzed statistically by us to quantify the words that most children appreciate, such as family, food, play, school, teacher, among others; As well as define the degree of acceptance of the exercise by the children and their teacher in order to obtain data that help us in the application of new exercises using the notebooks as a means of expression. The notebook could become a dynamic of sharing among children, their peers, their parents and their teacher.
