Not only can the educational tablet provide all the courses studied during the past year, facilitating revisions and allowing exercises to be redone at leisure, but it can also be loaded with modules specific to summer learning, creating the link between the program of the past year and that of the year to come. A specialized educational tablet specifically designed for school use such as the NovaPad tablet can also be loaded with specific modules and exercises decided and/or designed by the teacher and adapted to the specific level of the child and his particular review needs. The game as a learning tool Summer is more conducive to differentiated and gentler learning than in a school environment. Thus, educational games are particularly suitable for bringing out new concepts, or reviewing notions already studied.
