Mobile Montessori is proud to present the Movable Alphabet! After learning to identify and blend the sounds of the letters of the alphabet children are often ready to build words on their own. However, the ability to write them down with paper and pencil may require much more time and practice to acquire. Therefore, Dr. Montessori prepared the Movable Alphabet for children to β€œwrite” words, long before mastering the physical skill of writing. Children can phonetically sound out words, one letter at a time to build words. The app includes over 40 images of simple words, along with audio pronunciations and instructions, for children to practice with. Additional word sets are available via InApp Purchase! One unique feature in this app, are the buttons in the box above each letter. Children can touch the buttons to hear the sound of the letters, giving them the ability to "search" for the sound they are thinking of to build their word! ***** REVIEWS FROM OUR CUSTOMERS: "Thank you so much for the Cursive Edition of the movable alphabet. We've just downloaded it and my son is using it with great success!" ***** About the Word Sets: Once the children begin the process of composing three letter words (consonant-vowel-consonant) with the Movable Alphabet they are encouraged to move on to building four and five letter words. In our experience in the classroom, it is best to follow the CVC words with four letter, CVCC words, which often seems to be easier for the blending of sounds leading up to the actual reading of words. Mastering word building requires lots of practice and repetition. Following this, we introduce four letter, CCVC words and then five letter, CCVCC words. As the children master these skills they often explore the process all on their own and have fun expressing their own ideas using the Movable Alphabet! Word Sets 1 & 2: CVC (consonant-vowel-consonant), three letter words (bat, fin, jug, etc.) Word Set 3: CVCC (consonant-vowel-consonant-consonant), four letter words (fast, bulb, hand, etc.) Word Set 4: CVCC (consonant-vowel-consonant-consonant), four letter words ending with β€œck” or β€œnk” (sack, rink, tack, etc.) Word Set 5: CCVC (consonant-consonant-vowel-consonant), four letter words (clap, flex, spot, etc.) Word Set 6: CCVCC (consonant-consonant-vowel-consonant-consonant), five letter words (drink, twist, slept, etc.) Dr. Montessori observed in her work with children that after working with the Movable Alphabet children experienced an β€œexplosion in to reading!” Our goal is to bring a sampling of this excitement to a large audience via the Movable Alphabet on the iPad! We thank you for your support of our apps and hope you enjoy this one! Visit our website: http://www.mobilemontessori.org App page: http://www.mobilemontessori.org/movablealphabetcursive
