A set of NaviLens codes designed to make the numbers 0-15, math symbols, and a math problem "speak for themselves” in 35 spoken languages and "sign for themselves" in ASL (American Sign Language) is now available free from Teachers Pay Teachers thanks to the generosity of the wonderful people of NaviLens.

These dual-purpose NaviLens codes can be added to flashcards or other materials to help students learn math braille and/or sign language.


Both ”Try its” below work with both NaviLens GO and NaviLens. Use the NaviLens GO app if you’re an ASL speaker or learner. Use NaviLens to listen to both codes in the language of your phone. NaviLens will speak what's on the code including the braille needed for it (Nemeth for this set of codes).

Try it #1: Scan the NaviLens code on the image above. You'll need to display it on a computer or tablet or print this post to scan it. If you scan it with the NaviLens GO app, you can experience a short ASL video for the number 12 after changing Preferred Content to Sign Language using Settings (the blue gear). The ASL math video for ”12” is one of 500+ available in ASL and SEE in the Texas Math Sign Language Dictionary, which they share with a Creative Commons license*. You can learn more about how this library was created here on their About page*. If you appreciate this awesome resource, be sure to share your thanks with the creators & supporters of this phenomenal resource using their Contact page*. [* = Links coming]


 

Try it #2: Scan the image above, which is of a 3” x 5” flashcard that I handwrote the math question ”How many are 3 dozen?” and added a 1” (25mm) square NaviLens code to. If you scan it with NaviLens, NaviLens will display the text of the question and speak it in the language of your phone. If you scan it with NaviLens GO, then you can experience the question asked in ASL by Dr. Bill Vicars, Professor of American Sign Language and Deaf Studies at ”Sac State” (California State University, Sacramento). and president and owner of the Lifeprint Institute, a consultation business focusing on technology-enhanced delivery of ASL Instruction (and more!). Dr. Vicars gave me permission to use this one of his ASL videos.

Soon, I’ll add another code to this set with the answer to this question. This tag would be added to the reverse side of this card. When scanned with NaviLens GO, it will answer the question in one to many sign languages (ASL, BSL, CSL, SSL, etc) giving the complete answer ”Since 1 dozen equals 12 then 3 dozen equals 3 times 12 which is 36.”. When scanned with NaviLens, it will display the answer above in text or be spoken in any of 35 languages.
