Developed for Mayerson Academy's accredited Orton-Gillingham training programs now offered online, this simple and effective Orton-Gillingham electronic card deck enhances understanding of over 80 common grapheme-phoneme correspondences that form the building blocks for reading and spelling. Each grapheme* card offers the multisensory experience of hearing the corresponding phoneme and key word, watching a video clip showing articulation of the phoneme, and the opportunity to practice the phoneme with a voice recording/playback option.
- Easy-to-navigate, multisensory flashcard approach for in-depth practice or quick review
- User-friendly interface with clean, modern graphics that appeal to children and adults
- Use with Orton-Gillingham based reading programs or in conjunction with any phonics-based curriculum
- Useful literacy tool for educators, university students in education-related fields, reading tutors, O-G practitioners, Speech-Language Pathologists, ESL learners, parents, and children
- Learn the logical sequence of multiple spellings for 21 graphically-represented phonemes
- Select one or more categories for each practice session, including consonants, single vowels, consonant digraphs, vowel teams, vowel + r, short vowel signals, VCe, and common suffixes.
- Toggle easily between controlled and random presentation of graphemes
- Record/playback feature allows users to hear their own pronunciations
- Multiple Spelling Practice gives you the ability to hear and see the sound being dictated, write down the multiple spellings, and check your answer.
- Use the app independently or supplement with a printed version of Mayerson Academy’s O-G Card Deck
- Enhance the multisensory experience by simultaneously tracing/stating each grapheme-phoneme correspondence in a nearby rice tray or on a textured surface

What an amazing app! Students have a practice tool and teachers have a reinforcement tool for correct phonology, as well as a tool for intensifying instruction in the spot for deeper work on the formation of speech sounds! Thank you!

Shuffle feature needed!


I love this app, it's easy and convenient to always have your OG deck with you!

I wish it had a function to shuffle the cards so that the students were not always reviewing the sounds in order.

Amazing resource!


The Mayerson Academy OG Card Deck has been an invaluable resource in my classroom. My students love using it independently and in small groups. A must-have!
