Plan phoneme-grapheme mapping lessons, explore speech sounds, and teach letterbox lessons on screen — with supported word lists organized by phonics pattern.
Choose the right words, map sounds to spellings, and move straight from planning to teaching. No student accounts required.
Choose the question that sounds most like what you need today.
Use organized word banks or type your own words.
Use the Phoneme Counter to count phonemes and review phonemes, graphemes, and letterbox mapping.
If you build a lesson list, print the letterbox lesson plan or continue to the interactive lesson screen to teach with drag-and-drop tiles.
Count phonemes in a word, review phoneme-grapheme and letterbox mapping, and build a lesson list when you want to teach those words. Print the plan or send it to the interactive Letterbox Lesson.
Teach a lesson built from the Phoneme Counter using sound boxes, drag-and-drop letter tiles, and check/show-answer controls for live instruction.
Letterbox lessons work best when words map clearly sound by sound. The Phoneme Counter helps teachers choose words intentionally, check the mapping, and move from planning to explicit instruction when they are ready to teach. Explicit modeling, guided practice, and well-chosen words do the teaching; the tools just make them easier to prepare.
Wondering which letter-sound correspondences or phonics patterns to target? Start with a quick check on the Assessments page. Lesson taught? Build practice with the same words — load them into a game, spinner, or flashcards in Build & Play — and when words become sentences and passages, the Fluency tools take over.
