Placing a point on a grid, drawing lines, drawing figures as proposed by this application can appear as simple and easy. This is not the case and this application that makes it possible to work on the problems of axial and central symmetry is very rich. The "Free Drawing" part full of possibilities practically covers the field of Euclidean geometry: point, line, flat geometric figures, areas, mediator, diagonal, angles etc. Everything seems feasible and the initiation to fractions is even possible which makes it possible to divide a given line or figure into equal parts.

What will I find? ============== • Three ways of enjoying the same story: 1 For the child who still does not know how to read and needs to discover the world through simple words. 2 For the child who can read with more precision and wishes to explore more details of the story. 3 For the child who already knows how to read and is capable of fully undertaking the adventure of discovering the pleasure of reading. • Seven languages so you can switch between languages, familiarize yourself with a new one, or simply practice two mother tongues. • Reading comprehension activities tailored to each level. Learning to read is about more than pronouncing the phonemes in the alphabet and spelling words. • “Achoo!” What could happen to a ladybug when she is allergic to the plants of the forest where she lives?

I really liked how you could grade content to this book, depending on the level of a child's competency. There are no IAPs or ads, and I would definitely recommend this to families and teachers. K-5 Está muy bien! Parece un cuento, pero es mucho más. Mi hija ha de cinco años mejorado la lectura y disfruta haciendo las actividades. Es genial para después que han aprendido el abc. OPINIONS ON AUCADIGITAL APPS “(…) At the beginning of the stories, there are settings that can be modified to suit the needs of a particular child. It is possible to choose from three different levels of difficulty in the text. The text can be displayed in block letters, in cursive, or in all capital letters, depending on your preference.” (http://www.funeducationalapps.com/) “(…) una de las mejores aplicaciones para niños de iPhone y iPad que hemos encontrado ya que aprovecha al máximo el uso y la posibilidad de los cuentos.” (http://appleweblog.com)
