Children know a language when they associate words with images and sounds—this facilitates the assimilation of knowledge. This research uses applications based on augmented reality, which are designed to help teachers who want to teach another language, particularly English. The set of useful terms for the student to learn is defined in various categories such as animals, colors, and things. These terms are stored in a database with different formats such as text, 3D image, audio, and video which are associated with items that contain, in turn, a vocabulary which represents abstract entities, which are necessary to complement the learning of a language. The words are associated with the images and with the corresponding audio so that the students learn to read, write, listen, and, consequently, pronounce the words correctly. This research is projected as an innovative technological support that helps primary school teachers in the process of teaching the English language, and it is expected that in the short term it will become an indispensable basis for this educational dynamic.
