As a school-based occupational therapist, I often see both general and special education students struggle to learn proper letter sizing and placement when writing. HOUSE-mouse Flashcards were designed to assist students with building visual perceptual awareness of letter/# sizing and line placement differences. Children readily understand that a house is "tall" and a mouse is "short" thus this concept has been applied to HOUSE-mouse products. Each letter/# in this flashcard set has a corresponding picture cue for correct sizing beside it. Cut-outs can be glued to the front/back of standard index cards and used for both classroom and home practice activities. This set includes all upper and lower case letters as well as numbers 0-9. Recommendations for specialized verbal cues as well as activity ideas have been included.
