Filling in the Missing Letter

SKILL: Writing

DIFFICULTY: 1/5

LEVELS: 12 based on word length and position of the missing letter

BRIEF RATIONALE: This treatment is a step toward spelling words using reading skills to aid writing.

In Filling in the Missing Letter, you will see a word that is missing one letter and drag the missing letter tile into place. The treatment auto-adjusts in difficulty based on performance.


HINT: A hint button is available in the lower-left corner of the screen to reveal the correct letter in the first available space. Using the hint will mark the item as incorrect (as it was not answered independently), but may help you complete the word.

FOR THE CLINICIAN: This treatment involves phoneme-to-grapheme conversion (PGC), meaning the patient must convert a sound to a letter to complete the word. The purpose of this PGC task is to improve spelling and writing abilities.
