Math Assistive Technology Devices
Assistive Technology (AT) tools for math are designed are designed to help people who struggle with computing, organizing, aligning, and coping math problems down on paper. With the help of visual and/or audio support users can better set up and calculate math problems.
Types of Assistive Technology Devices for Math
There are many assistive technologies used for math. I will focus on devices used in elementary schools.
Devices to consider:
A talking calculator has a built in speech synthesizer that reads aloud each number, symbol, or operation key a user presses; it also vocalizes the answer to the problem. This auditory feedback may also help a student check the accuracy of the keys he/she presses and verify the answer before he/she transfers it to paper.
Base Ten Blocks
Base ten blocks are popular in elementary school mathematics instruction. They are frequently used in the classroom by teachers to model concepts, as well as by students to reinforce their own understanding of said concepts. Physically manipulating objects is an important technique used in learning basic mathematic principles, particularly at the early stages of cognitive development. Studies have shown that their use, like that of most mathematical manipulative, decreases as students move into higher grades.
Tangrams are used to help students to understand geometric ideas by using a manipulation set. In addition, they create vivid images for visually impaired students. They are used by moving pieces around and combining them together to create other shapes.

The tangrams are generally used for elementary grade students but can be used as manipulative...
