Bilingual Center anyone? If you are looking for a good dual language bilingual center, look no more. This center is simple and practical. Students will match uppercase and lowercase letters to the alphabet mats. After they have mastered this, they can then match the uppercase to lowercase, and lowercase to uppercase. Now they have mastered letter knowledge! NOW they will develop phonemic awareness skills when they are matching the initial sound to the corresponding letter. These initial sound sorting mats are in both English and Spanish and goes with the Gomez and Gomez Dual Language Program. Watch your kids become experts in your alphabet and/or literacy centers! Everything is included (letter tiles).
