Double Sandpaper Letters, International Print give children a tactile, lower case letter set on pressed boards painted green and covered in sandpaper, guiding the hand through the exact shape and direction each print letter is written. Every board leaves space on either side so a child ages 3 to 6 can steady it with one hand while tracing the rough letter with the other, building the muscle memory needed before handwriting begins. The consistent green finish keeps a young child's attention on letter shape during tracing practice.
“Free the child's potential, and you will transform him into the world.”
The Double Sandpaper Letters address the complexity of international language systems where digraphs represent single sounds distinct from their component letters. Each sandpaper digraph card creates a tactile pathway that connects the visual symbol to its unique phonetic value, preventing confusion between individual letters and their combined form.
The green background of these double-letter cards distinguishes them from single sandpaper letters, signaling to children that 'ch', 'th', or 'qu' function as unified sound units. Through tracing these sandpaper combinations, children internalize both the motor pattern and the phonetic principle that two letters can merge into one sound. This material bridges the gap between learning individual letters and reading fluently in languages where digraphs are essential. The sandpaper's rough texture against the smooth board creates sensory feedback that strengthens the neural pathways between seeing, feeling, and eventually writing these letter pairs.


Follow the Montessori method of presentation for optimal child development.
Place 2-3 digraph cards on a mat. Sit to the child's dominant side. Have a small tray with paper slips showing words containing these digraphs nearby.
Introduce the first digraph by tracing it slowly with your index and middle fingers while pronouncing its sound clearly
Invite the child to trace while you repeat the sound, watching their finger movement
Present three digraphs using the three-period lesson format
Show word slips containing the learned digraphs, underlining the double letters

Tracing sandpaper letters creates muscle memory patterns that support future writing skills and letter recognition.
Learning double letters as units helps children recognize and produce digraph sounds in reading and spelling.
Introduce digraphs only after the child knows most single letters to avoid confusion
Everything you need to know about this material.
Contact Our ExpertsThis set includes common digraphs and double-letter combinations found in international languages. The specific combinations vary but typically include sounds like 'ch', 'sh', 'th', 'ph', 'qu', and other language-specific digraphs that appear frequently in European and other international languages.
Children trace the sandpaper letters with their index and middle fingers while saying the sound aloud. This multi-sensory approach combines tactile, visual, and auditory learning. The child traces from left to right, following the same direction used in writing, which helps develop proper letter formation habits and muscle memory.
The green background is specifically chosen in Montessori materials to indicate letter combinations or digraphs that create a single sound. This visual distinction helps children understand that these two letters work together as one unit, differentiating them from single consonants (pink) or vowels (blue) in the traditional sandpaper letter sets.
Children should be introduced to Double Sandpaper Letters after they have mastered single sandpaper letters and can blend simple three-letter phonetic words. Typically, this occurs around age 4-5, when children are ready to explore more complex phonetic patterns and are developing greater fine motor control for tracing.
Regular Sandpaper Letters present individual letters (one per card), while Double Sandpaper Letters show two letters together that create a single sound (digraphs). Double Sandpaper Letters are introduced after single letters to help children understand that some letter combinations work together to produce sounds that cannot be decoded by sounding out individual letters.
