Signing Math and Science Dictionaries

For Signing Math & Science, TERC and Vcom3D are using the SigningAvatar® assistive technology to develop illustrated, interactive 3D standards-based sign language dictionaries that offer students in grades K-8 and 9-12 who are deaf and hard of hearing increased access to the same learning opportunities that hearing students enjoy.

Students using the Signing Math and Science Dictionaries on a laptop.

Video versions are available compatible with Mac, Chromebook, and a wide variety of platforms and web browsers and with iPads all at no cost.
