Mental addition and subtraction with GimmeFive is a workbook and software program (downloadable with the activation code included in the book) designed to encourage the development of sequential composition and decompensation strategies that are involved in the mental calculations of addition and multi-digit subtraction. The volume is divided into two parts. The first part presents the difficulties related to learning mental calculation and describes the environments and functionalities available in the software to support the learning process.  The effectiveness of the educational approach which is centred on the use of the program to distinguish disorders from learning difficulties and to build a path of recovery and skill-strengthening is highlighted. The second part of the book shows the didactic proposal that follows the eight modules presented in the software and that has been expanded upon with activities to be carried out individually, in pairs or in cooperative groups. In this sense, the GimmeFive didactic program constitutes an inclusive educational program for the development mental addition and subtraction skills aimed at all primary school pupils.
