The Signing Math Picture Dictionary (SMP) is an illustrated, interactive 3D sign language dictionary with 563 math terms defined in both American Sign Language (ASL) and Signed English (SE). The SMP is one in a series of fully animated, illustrated, and interactive 3D signing dictionaries. The SMP is designed for grade K-4 students who are deaf or hard-of-hearing and use American Sign Language (ASL) or Signed English (SE) in the classroom.

The SMP supports access to standards-based math content among lower grade elementary students and is a great resource for teachers and parents!

The SMP will link to definitions in our Signing Math Dictionary, Signing Science Dictionary, and Signing Science Picture Dictionary, all three of which can be found on iTunes.

Our 3D character, or avatar, can be zoomed in or out and rotated to give you the best vantage point for every sign. YOU the user have full control of the placement of the character!

Use the controls to choose the character and type of sign language you prefer; view the illustration; speed up or slow down the signing; and send the character to his or her "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.

The SMP also features an audio version of the dictionary pages. You can click on the sound icons and hear each part of the text spoken clearly as you read along.

Use the Quick Start Guide in the app to walk you through what the SMP has to offer. For a full description of how to use the SMP, go to www.signingapp.com.
