+++ Dyslexia Quality Award Winner 2015 +++ This entertaining and educational matching game app helps you practice your German grammar and spelling in a fun way. Whether you need to brush up on parts of speech, conjugation or declination, tenses and types of sentences - no matter what you need, the various grammatical areas can be combined with each other and practiced. With one click, the appropriate themes are chosen, easy as pie, and you can start right away. Matching pairs must be found, either by purely assigning terms to the proper categories (intelligent = Adjektiv | Ich werde spielen = Futur 1) or as a concentration-enhancing matching game. THE GRAMMATIK DUELL HELPS YOU PRACTICE YOUR KNOWLEDGE IN A FUN WAY Both the number of card pairs and the number of players are, of course, variable. Depending on your wishes, the cards can be read aloud, and the length of time in which the cards are revealed is adjustable. The difficulty level of the app increases with the number of card pairs and the chosen area of grammar. It is aimed at all students who are not yet entirely comfortable in their use of grammatical terms or who want to practice for their next grammar lesson in a fun way. You can also work on improving your spelling. STRONG MOTIVATION TO LEARN GRAMMAR On your own in a race against time or against a challenging opponent - who will use the fewest number of moves to find the matching pairs? Who will collect the most stars and end up the winner in this grammatical duel? The beautiful visual presentation of the playing cards, the acoustic sounds of success, the pleasing voice that reads aloud, the game variations, the pedagogically sophisticated content and the strict limitations of only relevant content make this app a truly worthwhile learning aid.

tabDo! is an innovative app and teaching method for learning music—notes, scales, and playing melodies—on tablets. tabDo! helps the learner develop an inner feeling for notes. During music lessons children actively discover the world of sound by playing well-known melodies, modifying and transforming them, and improvising their own tonal sequences. In the beginning basic melodic skills are trained with solmization—from four-note motifs to the pentatonic scale, then on to the chromatic scale. From listening and playing to reading notes. tabDo! is perfectly suited for all levels of classroom music activities. In this app three different functions are integrated, each of which can be used by either one or two children: The “Guidonian Hand”; a vertical ordering of tones similar to that of a glockenspiel; and a horizontal display of the notes as they are related to the notation. In all three functions the root tone or tonic can be freely varied. Up to 7 levels or degrees of difficulty are available, offering a broad range of notes which can be accessed by students. tabDo! can be adapted to any and every level of learning. The teaching units in tabDo! are ideal for 15- to 20-minute exercise sequences. The flexible app can be used independently of any particular course or song book. With headphones students can also practice exercises and learn music during quiet periods in class. A separate Handbook of Methodologies (HELBLING) offers a wide spectrum of ideas about how to integrate the app into teaching lessons. It shows how easily and effectively tabDo! can be used to train music-listening and note-reading abilities. It also contains a wealth of suggestions about lesson planning and exercising musical skills. What tabDo! offers, in a nutshell: ►Develops audiation skills (comprehension of music notes and their relationships) ►Trains and furthers basic music listening competencies, as well as social skills ►Enhances individualized learning—adapting to the student’s learning speed and level ►Introduces musical notation so that children associate notes with their sounds ►Promotes music-making in the classroom right from the start
