Dear all,

    APH is seeking teachers to evaluate and test Cosmic Number Lines, a
math game for iOS devices. The app is designed to help early elementary
school students with blindness or low vision—specifically, second and third
graders—learn numeracy concepts and skills through interactive number
lines. Some of the foundational skills your students will learn include
constructing a number line, locating points, comparing numbers, finding
distances, and solving addition and subtraction problems. This app would be
a great supplement to classroom instruction by strengthening all students’
understanding through fun gameplay, regardless of their level of vision.

    Testing will begin in March 2025. If you have an iOS device and are
interested in testing this app with your second and third grade-level
students, please fill out an application form by February 14th, 2025 at:

you for your time and consideration!
