Teaching sign language to the Mexican population is the best way to integrate more than 2 million deaf people into society. But with only 10 teachers in the entire country, it is an almost impossible task.

That’s why, on National Day of the Deaf, we launched TikTok Teachers. A completely organic challenge that took us from 10 teachers to 3.4 million teachers live. We became trending for four days and created the first sign language dictionary on TikTok, gathering in a single hashtag 1,300 words that make up the original dictionary.
