What it is
Summary
AI-generated from vendor-published content · May 23, 2026
The Number Line Device is a tactile math tool designed to help students who are blind or have low vision build a concrete understanding of number line concepts — positive and negative integers, fractions, and basic operations — through hands-on manipulation rather than visual representation. A student who struggles to grasp abstract numerical relationships on paper can use this physical device to literally feel the position of numbers relative to each other. It's a self-contained tactile kit, not software, so no screen or computer is required. APH no longer includes the companion CD-ROM with current versions of this kit, so if supplementary digital activities were part of your lesson plan, you'll need to source those separately.

- A teacher of the visually impaired (TVI) or math educator familiar with tactile learning tools should integrate this into structured math instruction.
- Coordinate with the student's IEP team to align use with specific math curriculum goals.
