Signing Math Dictionary Signing Math Dictionary

The Signing Math Dictionary (SMD) is one in a series of illustrated, interactive 3D sign language dictionaries and pictionaries. The SMD is designed for grade 4-8 students who are Deaf or Hard-of-Hearing and use American Sign Language (ASL) or Signed English (SE) in the classroom.

The SMD supports access to standards-based math content among elementary and middle school students and is a great resource for teachers and parents!

Our 3D character can be zoomed in or out and rotated to give you the best vantage point for every sign. YOU control the placement of the character - not us!

The dictionary contains 705 math terms and will link to definitions in other dictionaries and pictionaries from our series.

Use the controls to choose the sign language you prefer; view the illustration; speed up or slow down the signing; and send the character to his "home" or default position. The signing will automatically loop until you go back (using the "back" arrow in the top left corner), thereby exiting from the signing page.
